You should not have removed the tensioner to install the belt. It has a pivot point that and can be moved in order to release the tension on the belt. Once you install the new belt, leave it off the tensioner until last, pivit it and install the belt oner the tensioner.
How long will it take to replace a belt tensioner unit and serpentine belt in a lexus 1996 sc300?
The belt tensioner on most GM vehicles has either a 15 or 16 mm nut. Put a socket on a long breaker-bar and use it to back off the tensioner.
usually you don't. Use a socket wrench with an extra long handle or "breaker bar". Turn in the direction indicated on the tensioner, and the tensioner will move enough for you to remove the belt. Once the belt is off, you can remove the tensioner if you have to.
there are two tensioners, the serpentine tensioner and the timing belt tensioner. the timing belt tensioner is behind the timing belt cover ;)
there is no repair for a belt tensioner. just buy a new tensioner. remove old belt, remove old tensioner, it is held on with one bolt. install new tensioner. install new belt
The easiest way to test a belt tensioner is to pull upward on the belt. The belt should be tight with very little slack if the tensioner is working.
If the belt is old it may be stretched to far for the tensioner to pull tight but If the belt is new then it could either be wrong belt or the tensioner spring is faulty. Be sure the belt is on properly if it isn't on one of the pulleys it won't tighten, also be sure you are putting it on the tensioner(you have to pull tensioner using a large wrench or breaker bar and slide belt on to it last,after other pulleys) I know it may sound like common sence but I've had friends who tried putting it on the tensioner first attempting to use the belt to move the tensioner.
auto store usually special order for a timing belt tensioner or belt tensioner
u do not adjust belt tensioner if belt is loose, u need to replace belt as tensioner works automatically
Worn belt or belt that has stretched to the point the tensioner cannot keep the proper tension. The tensioner can also be defective. Replace the belt and the tensioner.
make sure you have a diagram, use a long box end wrench to torque the tensioner which is near the top. When you rotate the bolt head, it will relax the tensioner. Remove the belt and then replace around all components except the tensioner. Push on the tensioner wrench again to make room for the belt to go over tensioner.
