Should I Replace the Pulleys When I Replace the Belts?

[RallyEclipse98]

Thanks for stopping by.

Well I bought a '99 GS with 175,000 miles on it, bone stock. I will soon be replacing the blown head gasket and while the engine is apart, I will be doing nearly all the preventative maintenance I can. My parts list will come to about $500 without tax.

When I do the timing belt, I will replace the tensioner pulley and idler pulley.

Question: When I replace the alternator belt and the A/C, P/S belt, should I replace their respective pulleys as well?

My purpose is to keep the car running as long as possible.

I want the car reliable, but at the same time I am not one to throw money down a hole. Thanks for your insight.

Nope, no need to replace those pulleys. They are actually quite a bit different from the ones your timing belt sits on as they do not have bearings pressed into them.

Nope, they will last a long time

Huh?

Now I may be wrong, but what's that in the center of this 420A p/s & a/c idler pulley?

Check the harmonic balancer (don't know if you have one) for obvious damage. Check the pulleys for roughness (feel it while spinning the pulley) or any up/down wobble.
