A mouse got itself in behind the timing cover on my dad's Tundra. The mouse got et, the engine jumped time. Somehow the valves were OK. New belt and a bit of gore removal and it was back to normal.

Pros: valves were OK

Cons: engine jumped time

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.

Pros: has everything you need

Vehicle: Toyota

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

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

This was the most frustrating repair I've ever done. I've done plenty of timing belt/chain jobs before but this one sucked.

You can't tell if the timing marks are lined up, the belt doesn't have marks on it and no where on line tells you how many belt teeth there should be from one mark to the others to check your work. I buttoned it up and was off a tooth on the driver's side, I could have set the truck on fire. It worked fine after I did the job a second time.

Pros: worked fine after second try

Cons: frustrating repair, hard to align

Vehicle: Toyota 4runner

Pros: chewed up timing belt

Cons: snapped timing belt

Vehicle: Toyota Soarer
