there is no tension bolt ! if the belt is loose it is either a stretched belt or the tensioner is bad. the only bolt on a tensioner is the bolt that goes through center of tensioner to hold it to the engine. no adjustment. good-day ! on the tensioner there are a few marks to tell you if it needs replaced, it should be on the center mark if all is ok. if its on any other mark. replace belt or tensioner if needed. the marks are on the front side of tensioner accross from the center bolt. alt, water pump, etc, are all stationary.
There is no adjustment on the spring / Tensioner. You either have the wrong belt are the tensioner itself is bad. Replace tensioner are belt.
Remove surpentine belt,then take out bolt that goes through tensioner to engine.
remove the belt. then in center of the tensioner is a bolt that goes into engine. remove this bolt. then tensioner should come off.
this should be spring loaded self adjusting if not tensioner is bad.
no, unless the tensioner is bad, other than that just the belt.
Should be the tensioner that the Alternator belt goes to
GM tensioners are spring loaded to provide the correct tension on the serpentine belt. If the belt is loose, either the tensioner is bad or you're using the wrong belt.
Yes, a bad belt or tensioner can be related to a rough idle. If it is not tight enough, or worn it is not able to run as smoothly as needed to keep the engine running smooth.
If the tensioner cannot put a full 'load' on a new belt (as shown by the wear indicator markings on the side of the tensioner) - it's likely the tensioner requires replacing.NOTE: some sources recommend replacing it at 60,000A bad pulley (bearing) would be making whining/screaming noises.See "Related Questions" below for more
Possibly that the tensioner is bad or the belt glazed.
yes, if the tensioner is bad it will make a noise at idle, but when you rev it up the chain will get tighter and the noise will go away.
