I'm going to be doing some major work on the front of my 93 Aerostar's engine compartment soon.....changing the A/C compressor, radiator hoses, belts, etc. The van runs great at 173,000 miles and I plan on keeping it for quite a while as a second vehicle. Just wondering how long timing chains usually last in that engine, and whether it would make sense to replace it while I'm "in the area".
Wondering the same thing about the AutoZone rebuilt water pump I had to install while on a trip across country about 20,000 miles ago. It only had a 12,000 mile warranty, but is still working fine. I got
145,000 miles out of the original water pump. Are the rebuilt ones usually good for 100K or so?
