locate belt tensioner below alternator on pass. side insert 3/8 drive ratchet in center of tensioner pulley rotate to loosen belt remover belt
disconnect battery, remove the serp belt, unbolt the alt, and take off the wires then put the new one in the way the old came off
yes you have to remove the serp, belt to replace timing belt
The serp belt has a spring tensioner. It is not adjustable. To remove the serp belt simply put a wrench on the nut and push it inward to create slack in the belt. Then slip it off.
I just replaced the belt on my 06 and I had to take the tenisoner off to get the belt behind it, once I did that it was no problem.
There is a belt tensioner that is spring loaded and it adjusts the tightness of the serp belt. The tensioner is self adjusting as the serp belt stretches out from use. You cannot adjust the belt tension yourself. If your serp belt is showing signs of cracking on the underside then you should replace it. If you suspect the belt tensioner is not putting enough tension on your serp belt then it should be replaced. I had a 1991 Corsica with the same motor and I had a belt tensioner break. This caused my serp belt to come off.
REmove Upper rad support and rad fans and air box. Remove bolts from alternator and remove serp belt. REmove alternator though gap left by fans and air box.
expect about 2 hours labor and a recommdation from him to replace both serp belts and the timing belt too the serp belts need to removed to access the pump and the water pump is driven by the timing belt and if its gotten wet by the coolant it wont last long and may leave you stranded then its about 2 hours labor to replace the timing belt
If you have replaced all this it may not be a belt. It may be your alternator itself. These have bearings inside them and they do wear out. The only way to check is to remove the belt and spin the alternator to see if that is what is noisy. It may wobble if the bearings are bad. It should turn smoothly if not.
you need a serp belt removal kit that has a tool that you put on a pully which allows you to remove the belt. then get the belt that is the same size and follow the diagram that shows how the belt goes on if there isn't one then draw one on paper then put it on and do the opposite of how you took it off
it has its own belt. it looks like a serp belt but it isnt. its just a ribbed belt.
it is actually a belt but that doesn't matter. remove the serp belt, then the serp belt tensioner (1bolt), then the timing cover (4bolts), remove #1 plug and take it to TDC (top dead center). the timing marks on the crank and cam should be inline with one another. with a timing belt wrench take tension off of the belt and remove. install new belt and repeat in opposite order. that's it pretty easy really. I would recomend that you replace the water pump while you have it apart. it is ran off the timing belt and will fail at some point, and depending on your engine size could cause internal mechanical failure if it does fail. easier to replace while you are there and everything is dissaembled. good luck
Drain coolant from petcock valve on pass. side of radiator. Remove serp. belt. In between the V of timing chain cover is water pump. Four blots hold it on. may stick because of o-ring seal DO NOT pry on timing chain cover. Drain coolant from petcock valve on pass. side of radiator. Remove serp. belt.
