reminder belts and pulleys

i was on the 401 the other night and alternator belt's tensioner pulley broke.... then belt tore..

i was stranded for some 4 hours. sigh... now ill have to be in the cold garage fixing it myself... i dont even have a garage heater.

in hopes of saving you all from this mess, just thought id remind you to check the condition of your pulleys and belts.

While i have the belt off, any idea how i can check the water pump impeller without removing the water pump and spilling coolant?

Replacing the pully should be a 5-10min job, unless it broke the tensioner too.
Not much you can do about the pump, check for play or signs of leaks...

How often are pulleys supposed to be replaced?

There shouldn't be a need to replace pulleys unless they are damaged caused by something. They are plastic so they can damage quite easily. The tensioner pulley has more components, and can mechanically break so depending on the condition of the tensioner, if salt, or coolant has corroded it, it shouldn't be an issue. They generally are not a wear item. Belts on the other hand are, and should be checked and replaced every so often. Just check them for any cracks, or tears.

The pully on the tensioners has a bearing inside of it, and IS a wear item that will go bad after a while. If not changed in time, it will seize or fall appart, causing the belt to come off...Noise would be the first indication that something is wrong.

Yes, it can go "bad" but it's technically not a "wear" item. It can break from environmental components such as corrosion, etc.

Changed em all up a couple nights ago:

Idler pulley (pulley was missing a chunk, bearings completely worn)
Tensioner Pulleys (Drive one was gouged accross the belt surface, AC one was cracked)
Two new belts.

I can actually feel the smoother drive. and its deff quieter.

You're right. My apologies. I wasn't thinking of the actual bearing in the pulley. I was thinking more of the adjusting components in the tensioner. Anyways, ignore my previous statements. I had brainfarts lol.

Belts should be replaced once you see even the slight cracks develop. Check belts every oil change. Usually belts are replaced every 50k kms.

Pulleys are a wear item (whoever said they shouldnt need replacing is a fool). The factory grease inside the bearings will crap out in about 60k - 80kms for sure.

Also get CAA. Cant believe people still dont have CAA.
