If it ain’t broke, don’t fix it. I used to think that was my operating principle about many things in life, especially cars and houses. But if truth be told, it’s more like If it still functions minimally, don’t fix it. Case in point: in the last couple of years, my ’66 F100 had lost the following functions: heater and defroster, turn signals, one brake light, instrument panel lights, and any semblance of suspension damping and steering accuracy. In addition to these operating issues, rust had turned the floor boards into Swiss cheese as well as perforated the roof in two places. The windows rattled. Oh, and the battery was totally unsecured. And the windshield leaked. And…
Given that this summer involved a bit more staying at home and the rentals were fairly undemanding, I decided to break my modus (non)operandi, and tackle these issues. It’s really the first time I’ve done anything but just the bare minimum necessary to keep it running. No worries though; I’m not going to restore it. Just preserve it.
#1: Heater/defroster
Two years ago, I was greeted by the unmistakable smell of coolant when I turned the heater on, as well as a puddle on the floor. It was just heading into winter and I just didn’t feel like tackling it. So I bought a couple of rubber hose ends, yanked the heater hoses off the outlets on the engine, and plugged them.
I saw that as a temporary measure, as I was sure I’d hate not having a heater. But it wasn’t as bad as I expected. Our winters for the most part aren’t really cold, with typical January daytime temps around 40-45 degrees F. I don’t use the truck much in the winter, and when I do, they’re short runs to the transfer station, lumber yard or the yard materials outfit. And I had the dog along to generate a bit of warmth.
But when I embarked on this course of corrective measures, the heater was high on the list. So I ordered a core and yanked the old heater out. Yes, it had been leaking. And yes, this wasn’t the original, as there was lots of silicone in places where I wouldn’t have expected it to be, including where the tubes went through the firewall.
But it wasn’t just the core that needed replacing. A large quantity of organic material had found its way into the heater box.
I thought it might have been mice or rats, but it looks to just have naturally accumulated from falling in through the fresh air intake vents in front of the windshield.
I decided to do a bit more investigation, opened the floor fresh air vent (poor man’s a/c), and reached my hand down into the outlet drain in the wall cavity. It was totally plugged up. I slowly extricated a large amount of debris, and as I worked my way down lower, it was more like silt. Once I got it all out, I put a hose in there and flushed the rest out. I finally have functioning vent system drains again!
And I finally figured out why I haven’t been able to flip the lever between Heat and Defrost in quite a few years (fortunately it had been stuck in between, which is a blend of both). It was a stick in there that blocked the mechanism.
I even splurged for new heater hoses!
The original flexible ducting is starting to get a bit brittle and fragile, but it was intact enough to reuse.
The heater now works like new again, and I can actually switch between the various modes. What a luxury! I just took it out today, and it was so nice and toasty in there! I can finally retire the hairshirt.
#2: Battery Hold Down & Cable
I’ve gone through a few battery hold downs over the decades, and after the last one rusted away, I just didn’t bother. I avoid hard braking (or more like it’s incapable of that), and that applies to other G-force maneuvers. So the battery sat there quite politely. But hey, if I’m going to fix stuff, I might as well do this too. I ‘ve found these little anti-corrosion battery post felt things to work well. Oh, and I took the advice of a commenter who noticed that my positive cable had a funky clamp, and bought a nice new cable. I did replace the ground cable a few years back, so that’s got a few decades in it yet.
#3 Repair radiator:
(Some of you are going to moan and groan). Back in 2017, the slow leak in the radiator was getting worse and worse. I replaced the original with a $10 junkyard one about 20 years ago, but those days are long over. I took it to a couple of radiator shops, but their price to essentially rebuild it was shockingly more than a new one. The radiator repair business is history; in fact one of the two places shut down not long after.
So I went to Amazon and found one for under $100. Yes, the kind with plastic tanks top and bottom, with an aluminum core. If I’d looked a bit more and not just grabbed the cheapest one, I could have gotten an all-aluminum one for not a whole lot more, but I didn’t.
And sure enough, this past spring it started leaking, from a tiny crack near the filler tube. Jeez. It fulfilled all the stereotypes of cheap junky replacement parts. So I did a bit of YouTube research, and found that one can weld these. It just takes a soldering iron and some more of the right glass-bead filled nylon. So I bought a hose fitting for a couple of bucks, making sure it had the right kind of plastic. And then I ground away some of the existing material to expose the crack better, and then drilled two tiny holes on each end of the crack to help keep it from spreading. And then welded over it with material from the fitting.
There’s the end result. So far so good. But I’m realistic that it might not be a long term fix.
Well done with the radiator welding, I tried that on my Subaru but it kept cracking I even used another plastic radiator tank from another dead Subaru as filler rod so it was the same material but nope the leak remained in place, Heaters can be a right pain when they leak I used pepper in an old Holden Commodore not because I couldnt get another heater matrix but because of the difficulty of changing them Holden apparently hang the heater core from a chain and build the car around it and my car had factory AC which makes it worse but a large packet of pepper from a supermarket into the cooling system solved a leak which flooded the passenger floor quite fast and as far as I know was permanent as the heater still worked 6 months later when I sold the car.
You’ve done a nice amout of work to that truck. It looks fantastic, and anyone who says differently has no appreciation for a preserving a good set of tools, rather than replacement. I was going to mention my favorite parts of the restoration, but I can’t find one. And BTW, I have an instrument cluster from a late 90s Taurus in my toolbox that I regularly robbed bulbs out of, then replaced as the “unobtainable” parts arrived. FOMOCO was making serviceable clusters long after everyone else gave up.
It’s always gratifying to correct some LONG tolerated ills in our old vehicles! After successful completion, it kinda makes you wonder WHY you put up with the hassles for so long! And Paul, you got black heater hoses, LOL!!! 🙂
This was so immensely satisfying to read through. Freshening up the old workhorse that’s earned it in spades. And not a high dollar restoration on something that will be carefully driven on nice days, but real practical fixes with noticeable benefits as it keeps working day in and day out.
And that twin I beam looks just like the one on my pair of old Rangers.
Wow, that’s a lot of projects but all hugely satisfying ones that make a big difference immediately. The truck is set for the next 35 years with you now.
Thanks for the shop report, good job!
A couple of random thoughts…
’65 Ford with six may be the first vehicle that used what eventually became universal – cable actuated throttle, instead of linkage.
I deplore rubber hose on the pressure side of the fuel pump, it’s a recipe for fire. If it has to be then the hose condition should be kept under frequent close inspection.
Inspiring reading. Maybe enough to get me to start some long deferred work on my thirty-year-newer motorcycle. But your heater housing experience really struck a chord with me. Even though I’ve never had a vehicle for nearly as many decades as your F100, I do park outside and almost everywhere I’ve lived has had the kind of evergreen trees that drop small leaves and seeds year-round. Plus some deciduous trees that add to that load every fall (well, more like early winter around here). My ‘86 Ranger was bad, our New Beetle was perhaps worse, though the biennial dash top removal to replace the pollen filter provided good access. The Toyota’s have generally been a bit better, though not my 80 Series Land Cruiser. On that ruck, the cowling at the base of the windshield was fairly easy to take out, after removing the wiper arms and a few bolts. The first time I did that, after enduring a winter with very little defrosting ability, I found several pounds of good, moist compost under the cowl. Are these vehicles designed with garage storage assumed to be the norm? Or just for large leaves that don’t get trapped? Coast live oak, pepper trees, jacarandas and birch seed pods all seem to have evolved to have excellent one way access. I’ve actually had live oak seedlings sprout in there.
As for the roof, you’ll want to get some sort of paint over the primer sooner rather than later. Primer doesn’t like to be exposed to the elements.
Rather than trying to color-match the roof paint, I’d like to suggest painting it white. The ’66 Ford brochure on oldcarbrochures.com shows me that *one* of the available two-tone paint schemes was simply body-color paint with a white roof – there’s a truck in a lovely shade of blue with a white roof pictured in the brochure.

White is the easiest color to paint, and you don’t have to worry about trying to match the body color. I might suggest painting it with the Rustoleum roller job. There are dozens of websites and YouTube videos explaining how it’s done. And for the sake of getting it done fast and cheap, rolling paint (as opposed to spraying) takes a lot less masking and a lot less equipment.
As far as paint jobs go, a layer of dirt/dust covers a lot of sins.
Sounds like your efforts were very satisfying. Such a great feeling putting things back in order. Cutting out the rust and welding in new panels is the best way to go. Watch out for moisture that will get trapped under the rubber mat. A bright and functioning set of instrument panel lights is always a nice way to be greeted when turning the key. Nothing like turning back the clock on the suspension too!
Why are the plywood panels oversized? Looks like they go past the recess in the door stamping
Because someone had cut them, for speakers. The hole was one half in the removable panel and one half into the door. Otherwise I would have just tried to find some new panels.
Geez. Never understood why people butcher door skins for speakers, especially metal ones. Nice to see the old girl get so much love.
I don’t think that I’d be able to drive it anymore…Instead of looking at the road, my eyes would be looking at the shiny instrument panel, the new floor, enjoying the more quiet, smooth ride, etc. I think that you will enjoy driving it more, and it should be easier on the Tinnitus as well. I have three projects that I’m slowly working on, and Covid has allowed for extra time on these as well. One is almost the same colour of the truck, but has a red bordello interior!
On an older vehicle like yours, the battery cables are replaceable. On many new ones, they are integral with the entire wiring harness for the engine and maybe more. Aftermarket battery clamps are often cheesy, brittle and corrosion prone, so you have to be careful. Fortunately on my cars the cables bolt to the clamps. On many acquaintances’ vehicles, they don’t…crimped to the clamps instead.
I have a really nice spare heater box but it looks like your got yours buttoned up. Spare radiator too but the 65 and 66 radiator support is different. Those front vents are fun aren’t they as you try to twist your hand down into it. Note there is a ledge inside and the drain hole is about 1 x 1/2 ” rectangle so it easily blocks. I’m still working on my front suspension as the project morphed into a 100% rebuild complete with cleaning and painting. I learned as I went and could do it faster a second time. Just need the correct king pins so I’ll do an article on the rebuild and with a king pin quiz around Thanksgiving.
Took shots of everything as I had the camera at home which is why I am so bummed today. Yesterday I saw a 1980-82 Citroen CX 2500 in Yuba City with the black louvers on the rear window in a Wendy’s parking lot. Never seen one in my life but no camera 🙁
Below, under the lip is the drain which could be blocked with one leaf leading to rust out.
It’s very satisfying bringing a run down vehicle back to an enjoyable ride. You might have actually hit the spot of “peak satisfaction”. Everything you tackled was run down so bad it only could get better. I have done similar things to my vehicles. However, none of them was that close to the edge.
Well done!
Nice work, Paul!
Impressive range of tasks and skills.
OOI, how many manhours approx for these tasks?
I really didn’t keep track. I had the time, and I needed something to do. So I just kept at it on and off over a period of a few weeks.
Great stuff, what really warms my heart is the servicability of the old F100. You don’t have to stand on your head for hours to get to the heater core, and you can see a good chunk of the ground looking into the engine compartment. Amazing!
That’s one of the main reasons I’ve kept it all these years. It’s really, really easy to work on. Very simple, and lots of room just about everywhere.
I’ll never forget replacing the core in my son’s 626: brain surgery.
Ever replaced the heater blower motor in a 240 Volvo? You dismantle the car around the heater.
Well done Paul. What a treat to have a ‘new’ truck again. That glow of satisfaction is highly relatable.
At least you’ll get to enjoy the fruits of your labors. Quite often in my past, I deferred things until it came time to sell the car, then I had to hustle to get everything fixed prior to sale.
Great work! It would be cool if the original owner ever saw this truck still running well today!
Kudos! Replacing instrument light bulbs was always one of my favorite jobs – it was really easy and the result was fabulous. I got pretty good at being able to find those light sockets by feel. I probably still have a bunch of light bulbs for dash lights in my garage junk box.
The white paint on the roof sounds like the best solution. You can get big rattlecans of it and its really forgiving. If you can find old fashioned single-stage paint, all the better. You might have to go to an auto paint supplier, who may be able to mix some and put it in a spray can for you. The clearcoat stuff is a PITA when trying to do matching with surrounding non-clearcoated paint. Ask me how I know.
As a fellow past owner of a 1967 Galaxie, I have mixed feelings on IP light replacement. While my car had seen significant restoration before my time with it, I’d swear darn near every bulb was out. Several were quite tricky to get to from under the dash, and the bulb behind the non-existent clock was essentially impossible. Since the car did not have the clock, there was a certain logic to the appearance of the dash, but IIRC, the clock blank shared a bezel with the speedo, so the bezel sort of faded to dark at the right end.
But, I would agree that going from a near black dash to an array of lights certainly made the first night with the new bulbs more cheerful.
The flipside of the “Ackthpthpth, so much work needed; where do I even begin?!” is that every one of these repairs makes the vehicle very noticeably better. It’s much more rewarding than doing the periodic maintenance on a modern car so that it runs and drives just about exactly like it did before.
I can’t fault you for buying the plastic-tank radiator; the alternatives are universal crossflow aluminum radiators that work okeh but look alien and make a nuisance of themselves with relocated hose fittings, or highly excellent but very costly custom-built radiators. That plastic-welding technique is nifty!
My trick for that: once you’ve released all the terminals from their connector block (as applicable), tie a long piece of string or twine round the bundle of wires at the very end near the terminals. Withdraw the old switch, which will pull the string up the column. Untie it or cut it, tie it round the wire bundle on the new switch, then pull the string to guide the new wire bundle down the column without any of the wires snagging and refusing to show themselves at the bottom.
Your experience with LMC Truck matches my own: virtually everything they sell is of very poor quality, and often doesn’t even kinda fit/work.
I had pretty good luck with Rock Auto replacing power window mechanisms in my 2002 Durango. Much cheaper than OEM (if they were even available), and worked fine.
On the other hand, the aftermarket parts I got for the cooling system from one of the major auto chains were a disaster. I had to take every damn one out, and replace them with parts from the Mopar store.
Hit and miss.
My comment was about LMC Truck, who AFAIK aren’t a RockAuto affiliate.
My comments about RockAuto are here.
I still have trouble digesting the idea that the old-fashioned radiator shop has gone the way of the wood paneled station wagon. Going to an old radiator shop where torches glowed and where the floors were sticky with antifreeze, where some old guy could fix anything with a leak – that was something that was always there, until it wasn’t.
As the guy with a complete radiator shop stored in mothballs, I actually noticed the slow fade-away one no-longer-viable operation at a time.
I sometimes wonder what happened to the big time shops that had it all bet on radiator work, as would be seen featured in the trade magazines, which of course thrived on advertising that pushed for more and more investment in radiator work.
It’s both impressive and scary how much organic debris can get into places you don’t want it, and cause plugs or induce rust. Mr. Schafer’s lower fender cleaning in his F-150 hit home as I have an F-150 with the same general era body.
Bringing my mother’s ’95 Grand Cherokee back to life this summer to sell it also brought out the problem of organic infiltration – also through the cowl vent. Significant debris had gathered on top of the vent to the point of turning into a mulch, with rain driving bits down into the system. Shockingly, the AC still worked, and I used it quite a bit. It never did stop spitting the occasional bits of hard brown junk through the dash vents while I still had it.
I’ve done most of those repairs on my old Ford trucks. It’s quite satisfying to finally repair stuff that has been broken, poorly rigged, or bypassed. Rebuilding the column shift mechanism was very gratifying. It was a challenge to take apart and also to put back together, but it gave me the opportunity to understand how it works, and an appreciation for the engineers who figured that out.
My goal, like yours, is to keep my trucks going rather than restore or upgrade them. An exception to this policy that proved satisfying was to incorporate relays into the headlight circuits. It gives the headlights full battery voltage rather than whatever they get from the thin wires routed through the switch. The job was a pain, but my headlights are now nice and bright.
It is a great feeling when a job comes out like that. Turns out that those old vehicles are really not so Wbad to drive. As for your roof paint, why not make it a two tone and do the top in white? Well done Paul
I’m not a “Ford” guy, yet I loved seeing the success of each repair.
I did much the same with the instrument cluster, and replaced wiring through the door-hinge area of my Toronado. Took a heap of organic debris out of the bottoms of the doors, with actual live sprouts included.
Having replaced the ’66 wiring with nice, fresh wires…the damned squirrels or mice or whatever made a special point of chewing the nice, soft, delicious insulation of the new wires while leaving the original insulation on the remaining old wires mostly alone. Damn near caused a fire when the power window wiring grounded to the body.
New wiring insulation supposed to be more organic. To some extent, vegetable-based. Yummy!
I’ll join today’s chorus of appreciative readers–great! Me, I learned some of these kinds of repairs on my grandfather’s hand-me-down ’67 Chevy (power nothing, lots of room under the hood; rusty enough that any body work was a positive step). I can feel your pride and satisfaction. BTW, your confession of being a procrastinator–really?–helped me feel better about things I’d put off for much of 2020 and am finally getting to.
Big thanks as always, Paul!
Thank you for writing and sharing all of this! Really enjoyed reading it and the weather forecasters are calling for a rather wet winter. The windshield might have to be dealt with.
Nice work Paul! There is something soothing about working on a old Ford truck. Back in summer 2019 I replaced the glass run channel and beltline seals in the doors of my ’83 Ranger, with the parts from LMC, and wasn’t too happy with them. But everything else I have bought from them has been just fine. Haven’t checked yet to see if Carpenter has Ranger stuff yet. I too, like the white roof idea.
Good work on the repairs Paul. It is very satisfying to do small repairs that have big results. Like others said, get some paint on that primer. It will rust through. A decent paint shop should be able to mix up an aerosol can that is fairly close to your paint.
When I had my Suburban the original copper brass rad needed replacement. I was going to have the rad shop rebuild it, but even the rad shop owner talked me into a plastic/aluminum rad. For the money to rebuild the original I just couldn’t justify the price difference. Mind you, my burb was old and very high mileage so I wasn’t planning on keeping it forever. That said, I when I did the rads on my old cars, I invested in a copper brass recore job (upgraded for extra cooling though). Radiator rebuilding is a dying trade, so I am glad I got it done before it goes way. Considering the original lasted for 40 years, I expect the replacements will be around at least as long.
