AISIN Timing belt

Re the timing belt, if that has not been done I would get to that immediately. At 350K km it is a ticking time bomb. Use, specify, or supply the Aisin TKH-002 timing belt kit. It is OEM quality

Pros: OEM quality
Vehicle: Honda Pilot
Mileage: 350000 km
Part number: TKH002

AISIN Timing belt

I’ve used dozens of the Aisin TKH002 kits- they come with koyo bearings, a decent tensioner, and a Mitsuboshi timing belt, all very similar to the oem Honda parts. I think the only major difference is the Honda water pumps are usually made by Yamada and the aisin ones are made by aisin… I can’t say I’ve ever had failures with them

Pros: similar to oem Honda parts
Cons: Honda water pumps Yamada
Vehicle: Honda Pilot
Part number: TKH002

Mitsuboshi Timing belt

I bought a Mitsoboshi (not misspelled) from autohauz az a bit ago and it had a more round, but not completely half moon round, tooth profile than I've seen before on Contitech timing belts.

Pros: good rep, big company
Cons: round tooth profile

The timing belt failed kindly early 65k later, so could have been bogus Aisin parts.

Cons: failed early, bogus parts
Vehicle: Honda Odyssey
