All of my cars are over 100K miles now... What do y'all do, as routine maintenance, to keep your high-mileage cars running? Oil changes are a must, obviously (as is a timing belt about every 60K miles or so, if your car has one), but the other stuff isn't so clear.
I've seen recommendations to change the coolant every 30K miles. I've also had people (who seem knowledgeable) tell me to leave coolant alone, and to only change it if I have to change something else (like a water pump).
I've seen recommendations to change transmission fluid every 30K miles. That seems kind of excessive to me, but I'm really not sure. Are there any tricks for doing this yourself, with limited fuss? Unless you want to drop the pan (which I don't), replacing transmission fluid seems to require either some specialized knowledge, or a rigged-up tool that pumps fluid into your system (as you let it pour out via the return line from your transmission cooler).
I've been told to leave power steering fluid and brake fluid alone, until something warrants opening the system (like, if you replace a caliper, go ahead and flush the system; if your rack and pinion goes, replace the fluid).
How about the oil in a truck's rear differential? 30K miles?
Anyway, what are y'all's thoughts?
