It is obvious that whomever replaced the belt did something wrong. Take the car back to the person who replaced the belt.
Check all belts and anything that was removed while changing the timing belt, to make sure that nothing was damaged. If everything is ok, then the timing belt may be loose.
Sounds like the timing is off just a bit ur getting the start of detonation which makes the pinging noise ur hearing. That is the most logical (as or if ) it was not pinging before the timing belt was replaced.
A "knocking" noise sounds like a bad connecting rod bearing. You may be ready to "sling a rod". These engines are famous for it.
chain. if you hear a clattering noise the timing chain and timing chain tensioner need to be replaced they are usually sold as a kit
A Saturn 3.0 timing belt noise can indicate that the belt is becoming worn down. It can also indicate a bad gear.
It is not normal for a timing belt to make any noise. It is whining because something is out of place. It is either under too much tension or there is not enough lubrication.
Possible that the timing belt has been over tensioned.
no timing belt on a GMC Jimmy
The engine does not have a timing belt. If you are referring to the serpentine belt (the long belt that runs around the pulleys), it should be replaced when it shows sign of age. I replaced mine at 65k miles and it looked new. I hear people replace them anywhere from 80k - 90k miles. once
Timing belts are replaced, not reset.
there is no timing belt -- only a timing chain that does not need to be replaced
From 2002 HONDA replaced timing belt with chains ...so no more timing belt hassle.
