Chirping idle after new tensioner?

Recommended Posts

In a recent service on my E46 the main drive belt tensioner and pulley idler were replaced. Now it chirps / rattles quite loud at idle. ... ? Bad install, new parts wearing in or possibly something unrelated... what is the most likely option lol.

Take it back and have them recheck it. Could be waterpump or alternator bearing noise you are hearing

Yep, you're entitled to take it back and ask them what's up.

if you want to track it down yourself you can take off/loosen the belts (making a note of their path and direction of movement) and spin all the pulleys by hand until you find the cranky one.

getting back to this thread really late, but yeah it was just faulty brand new parts (top tensioner belt / pulleys). thanks to the team at Burgers for a speedy warranty replacement.

Was it some lower quality aftermarket brand?
