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.
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 belive that there is no adjustment on the serp belt on your lumina. Should be a spring loaded tensioner. If you are having problems with the belt slipping you most likely need to replace the belt/ tenssioner.
yes you have to remove the serp, belt to replace timing belt
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.
it has its own belt. it looks like a serp belt but it isnt. its just a ribbed belt.
You have to pull the pulley up on the left side of the engine, towards the bottom of the serp. belt and then just pull it off. It helps if you start at the top of the belt and then work ur way down to the bottom. You might have to take the motor mount off to put the new belt on, I had a hard time, but I'm a girl, so that might explain the difficulties that i had. lol. Hope it helped.
time for a new serp belt, maybe tensioner
how is the condition on the serp belt and belt tensioner? You should replace these to see if this could be the problem
Possibly a worn belt, seized/partially seized pulley (contacting serp. belt), worn belt tensioner or something melting to exhaust manifold.
locate belt tensioner below alternator on pass. side insert 3/8 drive ratchet in center of tensioner pulley rotate to loosen belt remover belt
Do you mean the "SERP" belt as in the serpentine belt that drives all the power steering. water pump, A/C and alternator pulleys. Hope this helps "G"
usually the serp. belt will shed because it shifts on one of the ridged pulleys. The most common cause of this is a failing pulley or a bad tensioner.
