Belt Maintenance on a 2000 Concorde
 

This is a noob question, but what are the different kind of belts in this car and how often should I change them?

different kinds of belts? u mean brand? U change them when they start to crack

No I meant like engine/serpentine etc.

I dont see the relevance of the question go to a parts store and tell them what engine size u have and they will tell u what brands of belts they have to sell you.
Or go tot eh dealer and get OEM ones.

There's 3 belts,the timing belt which according to the haynes repair manual should be replaced at 90,000 miles or 72 months and the drive belts which they recommend replacement at 7500 miles(I replace mine when needed,I still have the original belts).
