Shim to Correct Chirping Timing Belt on Honda Pilot

A chirp noise from the timing belt area can be caused by a tilted idler pulley. Installing a corrective shim from Honda will commonly correct this issue.

chirping on start, especially in cold weather

When starting the vehicle first thing in the morning, it will give a type of knocking sound or sweaking sound. The idler was mentioned as being the problem.

I had a chirping sound from the belt area which became worse when the vehicle was cold or in humid weather. I replaced the accessory belt, but this didn't stop the problem. I ended up having the dealer replace the timing belt, water pump, and install the shim kit so it doesn't happen again. It's been 6 months now and I haven't heard a problem since.

Replaced alternator 2 moths ago but when I start engine, a squeaking noise persists.

Same here. Have really liked this vehicle but at 60,000 miles it started falling apart. Belt chirping, water leaks, engine tapping, light keep blowing. Not happy.

Chirping noise when idling comes and goes. Dealer said it was just cause it was an older vehicle. Its a 2008!! I have a 1996 tacoma it doesn't chirp.
