Does the C5 Corvette Require Frequent Tune Ups, or Is It a Waste of Time and Money?

In the old days, tune ups were a part of car ownership, but the C5 Corvette is better suited for preventative maintenance. 

In the olden days, we were often told that cars needed frequent tune ups, which typically involved replacing wear items and performing other sorts of maintenance. Aside from the typical oil change, fluid flush, and tire rotation, this could include replacing things like the air filter, fuel filter, oxygen sensor, positive crankcase ventilation (PCV) valve, and spark plug wires. However, modern vehicles have come a long way in that respect, leading YouTuber Toys4Life to ask and answer the question – does the C5 Corvette, specifically, need regular tune ups?

The C5 Corvette is certainly a more modern vehicle than the ones that people were trained to take in for a tune up every 8k-10k miles, so the process of maintaining it is obviously different than something like a C3. So, to answer this question simply, our host says that the C5 Corvette doesn’t need regular tune ups, at least in his opinion. However, following a preventative maintenance schedule is always a good idea, and that’s also the case with this particular Corvette generation as well.

Luckily, the owner’s manual comes with one of those, and it’s a decent one, though there are also a few things that our host would add to that list. For starters, he recommends checking the oil every time you get gas, or even more frequently if you have leaks or take your car to the track. The same goes for coolant, as keeping tabs on that can certainly prevent major problems as well.

GM says to check tire pressure monthly, even with a TPMS system, and the manual transmission fluid twice a year. Our host adds that one should probably check transmission fluid in general any time the car is in the air, as well as the differential fluid, or more frequently if you suspect you have a leak. Then there are some safety items to check that should prevent the car from starting, such as when the clutch pedal isn’t fully depressed.

From there, we move on to checking the suspension system for leaks or damage, and tire wear – both overall and in terms of uneven wear that could be caused if the car is out of alignment. The exhaust system, brakes, and cooling system are worth inspecting from time to time, and you can also perform a pressure check under the hood and look for any hoses that might be wearing out and in need of replacement.

As far as the timing for all of these checks, the C5 Corvette owner’s manual has a suggested mileage timeline like most cars, with various items needing to be checked or replaced at certain intervals. Luckily, that information is still plenty relevant today, and for the most part, the average Shadetree mechanic should be able to perform these tasks in their own garage, if they please.
