Timing Belt Tensioner Ticking?? Sign In

2004 Isuzu Rodeo 3.2L 150K mi

Okay so here's the story:

Water pump went out so I purchased everything to do pump, timing belt, tensioner, pulleys. Got them them all replaced and the car ran great until the tensioner started ticking loudly. I was under the impression Auto Zone sold me a bad tensioner so I had it replaced under warranty and installed the new. Well now this tensioner is ticking also. It started ticking within 10 minutes of having the car put back together just like the other one did.

Okay here is the tricky part of the story... My Dad helped me replace the timing belt assuring me that he knew how to do this. I should have known better. We did not turn motor to TDC and align cam with markers. Instead he marked cam gears with white out and also marked heads (created his own alignment marks). We got everything back together and the car runs great just like it always has. So my question is.... could the belt be installed improperly if the car is running fine??? or could an improperly installed belt be causing the tensioner problem?? I am under the impression that if a belt is improperly installed then the timing would be off. Maybe the auto zone tensioner is not calibrated correctly?? I am about to order a factory tensioner but thought I would check and see if anyone has had this same experience.

Thanks so much for any help!!

This is the whole kit for that job..............

You should be able to feel a bad bearing of a tensioner. Could you be, fooled and it's something else entirely?

Yes you can run into a whole bad batch, sticks and not all too common but can happen. Ask for a different brand if you are sure that is it,
