200k Miles- What Should I Service?

[Bdc101]

At 7 years I would want to replace some of the cooling system parts, like the expansion tank, but if the radiator is only 7 years old, I'd bet it would be fine.

The CCV, you should inspect first to see if you have a lot of sludge. Pop off some vacuum lines to inspect. CT is pretty cold weather, so depending on your use, it would probably be time to change it.

You should also get under the car, remove the stiffener plate, and look for oil leaks. There are a lot of places that could be leaking and it's impossible to know for sure without taking off the plate. Power steering leaks are also super common and can be hard to distinguish from oil leaks, if the fluid is old and dirty. Inspect all eight of the CV axle boots from under the car as well.

Probably a good time for plugs, and change all the various fluids (front and rear diffs, transmission, and transfer case). If you haven't changed brake fluid in a few years, it's definitely time to do that too.


Have you ever replaced or repaired the DISA valve? It's probably bad if not. Get a GAS kit to repair it permanently.

Lastly, whatever records you have, turn them into a spreadsheet so you can track everything. I have a spreadsheet that I built from records the PO gave me, detailing every service ever done on the car, and it has helped save a lot of money by not doing things twice.
