Timing belt AISIN or Mitsuboshi

Paid $500 to a trusted mechanic. Ordered an AISIN timing belt kit and a Bando drive belt for around $250 (including tax and shipping).

Get the Aisin (OEM supplier) Timing belt and water pump w/ hydraulic tensioner kit (TKT021) from RockAuto (good price, authentic Aisin).

I used to be a Toyota parts guy, we used aisin kits for all our timing belt jobs on all the UZ V8s, all of them are the same layout.

AISIN TKT-021 kit has everything you need for timing belt/water pump. The water pump is driven by the timing belt, so always replace it when doing the belt.

I got mine off Rockauto. Aisin pump, Mitsuboshi timing belt, Koyo bearings. Reasonable price, as well.

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

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

Aisin timing belt kit is a few hundred bucks and very nice quality parts.

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.

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