1963 Buick Riviera: All The Maintenance The Factory Recommended (And My Modern Maintenance Schedule)

Modern drivers are spoiled by the extended maintenance intervals of their modern daily drivers, and EV owners have it even better with no oil changes or coolant flushes. Back in the 1960s, however, the factory expected that you would keep on top of a dozen or more tasks based on time and mileage. Using my 1963 Buick Riviera as an example, what was expected from an owner in the 1960s, and how might a hobbyist approach maintenance today?

1963 Buick Service Manual Maintenance 1

Luckily, both the factory service manual and the owner’s manual had a comprehensive list of what needed to be done, some of which was almost certainly disregarded. I’ll use the excellent service manual scans from TeamBuick.com to discuss the manual’s first chapter: Maintenance.

It’s worth noting that in 1963, maintenance intervals were relaxed quite a bit. Through 1962, Buick called for 1000-mile lubrication, and on a car like my 1953 Buick Special (seen above), that included well over a dozen grease fittings. The generator needed oiling. The distributor had a grease fitting. The kingpins had grease fittings. Therefore, by the standards of the day, a 1963 Buick needed far less maintenance than cars just a few years older, so keep that in mind as we discuss its maintenance recommendations.

Engine oil is the first thing most people think of when it comes to maintaining their car, and Buick called for 10W30 oil in general, but 20-weight oil was also acceptable. Notice the recommended change interval on page one of the maintenance section: 6,000 miles or 60 days. Few of us, then or now, drove 6,000 miles within two months, so Buick (and most other manufacturers) recommended oil changes six times a year if we assume the owner drove their car 12,000 miles a year (and to be fair, the filter itself only had to be changed every six months or 6,000 miles). How many owners honored that rigid schedule? It might not be as outlandish as you think; the 3,000-mile oil change still has its proponents even today, even if it’s unnecessary.

These days, given my large fleet and relatively low mileage driven, I change the oil every two years, which comes out to less than 2,000 miles. Many old car owners change their oil yearly or even twice yearly, but the only way to know for sure if you’ve gone too far is to send your oil into the lab for analysis (which I’ve never done). Starting an oil debate is outside the realm of my intentions here, but modern oil is far better than anything a Buick tech would have fed the Riviera back in 1963.

Page two shows this handy chart of what to check and when to check it, and it points out the areas on the Big Buick’s X-Frame where a technician will need to look. Notice that there are 6,000, 12,000, and 24,000-mile intervals between checks, nothing like the modern 100,000- and 150,000-mile intervals you’ll see in the manuals for a modern car, but certainly better than a 1953 Buick.

A sign that times have gotten a lot better in terms of automotive maintenance these days is the fact that the service manual outlines a flushing procedure for gunked-up engines. Leaded gas led to some ugly deposits in the oil pan and elsewhere (here’s a picture of the Riviera’s oil pan after I bought the car), so you’re unlikely to find such details in a modern service manual.

Buick recommended checking the battery level every time the car was refueled (which was often considering the thirst of a full-size Buick), something that you don’t need to do these days. I replace the battery every 8-10 years unless there’s a reason to do it sooner; for example, my 1974 Firebird barely started after its winter storage this year, and that battery was only six years old. Checking the coolant isn’t something you have to do anymore aside from checking out the level in the overflow canister, and almost nobody checks their oil regularly anymore. Many cars don’t use oil between oil changes; I know that my 2023 Challenger doesn’t, nor does my wife’s 135,000-mile 2012 Mustang.

The Riviera? Its 120,000-mile Nailhead uses about a quart every 1,000 miles, not too uncommon even back in the day, according to some things I’ve read.

Every 6,000 miles, the owner was, as I mentioned, expected to change the oil (unless 60 days had elapsed first). Then, the PCV valve (a new feature for most 49-state cars) needed replacing, and that’s something I almost never do, because back then, many part numbers were available, and they were tailored to every specific engine. These days, part quality is so spotty and choices so few that it’s best to hose the valve out with some carb cleaner and keep on trucking (in my opinion). Luckily, New Old Stock PCV valves are readily available on eBay if you need one.

The front end components needed a shot of grease at 6,000 miles, and this included tie rods, ball joints, idler arms, and sometimes upper control arms (depending on the make and model). As a comparison, Ford bragged that its 1963 Thunderbird needed lubrication every three years or 100,000 miles. Once again, few people drove 33,333 miles a year back in 1963, so it was more marketing hype than anything, but Ford must have improved the sealing of their suspension joints in 1963. I’ll lube the front end every time I change the oil, every two years.

The tech was also tasked with checking the master cylinder fluid level and lubing the heat riser shaft in the exhaust. I don’t have to do that last bit because, like most modern collectors, I’ve had the heat riser gutted because I’m not driving this thing on a zero-degree morning (one less thing to go wrong). On the other hand, I flush the brake system every three years because DOT3 fluid is hygroscopic, meaning that it attracts moisture. You can see how discolored the brake fluid becomes after three years; I should really do it every two.

Some owners will switch to DOT5 (silicone) brake fluid, but that’s something that’s better done when you’re replacing a complete brake system, as the two types of fluid don’t mix.

But you’re not done yet. The manual transmission oil needs to be checked (luckily for the tech, few Buicks had manual transmissions), as does the automatic transmission fluid level (which had a handy dipstick back then). Modern cars rarely need the fluid checked, and the dipstick is usually located somewhere that requires a lift and a glove because it’s located somewhere right next door to the catalytic converter. It’s miserable. Don’t forget the steering box or power steering pump level and the rear axle gear oil level. I check the rear axle whenever I think about it unless I notice a drip. Usually, I’ll crawl under and pull the plug every year or two. The Riviera had never had a fluid change when I bought it in 2022, and the oil was disgusting, so I’ve been sucking out the fluid and refilling it every year or two to clean everything up.

Don’t forget the door hinges, hood hinges, weatherstripping, tire rotation, and U-joints/CV joints. For cost’s sake, I’m lucky because the 1963 Riviera’s two-piece driveshaft uses three U-joints. I had them all replaced at the local driveshaft shop when I bought the car, and the technician asked if I wanted grease fittings. I asked for his recommendation, and he replied that unless I was going to grease them every couple thousand miles, I might as well get the joints with lifetime grease, so that’s what I did. It’s a good thing, because lubricating that center joint would be a bear. Other models used CV joints, which are certainly more expensive to replace.

Every year or 12,000 miles, there’s more to do. It’s time for a tune up, including plugs and points and giving everything a thorough check, including the ignition timing and engine compression (I’m sure few bothered). You did have to check the timing after a points change, however, because new points can easily affect the ignition timing. Don’t forget to check the air filter, wash and oil the breather cap, and grease the slip joint in the driveshaft (drat, I’ll still have to do that occasionally).

I’ve switched the Riviera over to a Pertronix system, and with unleaded gas, I almost never replace spark plugs unless I’m tinkering and trying different brands and heat ranges (or something’s run very rich at some point for whatever reason). I still use points in three of my cars, and they usually only need a yearly or biyearly pass with a piece of emery paper. I’d use points in everything if parts quality wasn’t an issue these days.

Every 18,000 miles, you should check the brake linings (they’ll last far longer unless all of your driving is stop-and-go), and you should repack the wheel bearings whenever you service the brakes. That’s something I do very infrequently, and the bearings are generally fine. Once again, I don’t drive the old cars a lot of miles.

Now, we’re onto two years or 24,000 miles, and you’ll need to change that fuel filter. I’ve found that fuel filters rarely go bad unless there’s debris in the tank, so I’ll check them occasionally, but nothing more than that. The automatic transmission needs to be serviced by draining the pan (an easy job on a Turbine Drive transmission), dropping the pan, and cleaning the screen. Back then, you’d fill it up with Type A, but that’s not available anymore, so I use DexMerc (the non-synthetic variety) fluid.

Buick called for antifreeze to be added in the fall and drained in the spring, with straight water with corrosion inhibitor taking its place in the warmer months. I think many of us use some antifreeze mixture these days; I use 50/50 because Michigan can drop to subzero temperatures fairly regularly in the winter. In the Riviera, I use conventional green ethylene glycol antifreeze and drain the radiator and block every two or three years. With some of my other cars, I drain the radiator and refill it at about the same interval, but the Nailhead has easily accessible block drains and the cooling system was very corroded when I bought the car. Clearly, no corrosion protection was used for a long time, but the antifreeze is finally staying relatively clean.

Don’t forget to lube the door hinges!

And all the rest of the little hinges. Dripless oil is your friend here, but honestly, how many gas station jockeys did all of this? How many Buick techs? How many owners?

1963 Buick Service Manual Maintenance 10

Rear axle oil was considered to be good for the life of the car, but Buick never expected that you’d be driving your car for 63 years. Don’t forget the additive if you have a positive-traction rear end.

If you do all this maintenance, your Buick should stay happy for decades; heck, even if you didn’t do most of the maintenance, it might be still kicking around for 63 years and more. Buicks were pretty good cars back in the day, but few today would be willing to keep on top of that much preventative maintenance. We’ve really been spoiled.

But then again, few modern cars look as good as a ’63 Riviera, so it’s worth it.
