AISIN® W0133-1850488-ASC - Automatic Timing Belt Tensioner

This kit was everything the description indicated it would be. All parts were name brand down to the koto bearings. It was packaged perfectly. My only comment for improvement would be the pull pin on the belt tensioner. It doesn't come out all that easily but would if the pin were made of a stronger steel. Thanks TRUCKiD!

All the parts in this kit have the same name as the original parts I replaced. (Can't read the back of the old belt though). The name Aisin is even cast on the front of the 3.0 liter engine above the timing alignment mark for the crankshaft. The original water pump has both names (Toyota/Aisin) on the housing. Quality kit and great service from TRUCKiD, can't do better than this.

Bought this kit and then ordered a new thermostat, accessory belts, seals, etc and it worked out cheaper than most of the full timing belt kits available. As others said the parts in this kit are all like like the originals. And in case you were wondering too, the black circular thing is a new thermostat gasket so you don't need to order a separate one like i did.

I debated on saving a few bucks for some of the cheaper kits out there, but I'm glad I went for this one. I won't have any nagging thoughts of timing belt failures while driving for the next 100K miles with these parts. All the items are of a very high quality; there are no defects in any of the castings or machined surfaces and everything is top notch.

I bought this kit for a 2001 Toyota Sienna which has the 1MZ-FE engine with VVT-i. I am usually suspicious of water pumps supplied by 3rd party vendors, but it turns out that Aisin makes the pumps for Toyota. The original pump even has their name molded into the casting next to the Toyota name. The pictures look as though the driven hub of the pump is made of plastic, but it is actually black-anodized metal. The belt was made by Mitsubishi and the bearings by Koyo. The pump gasket was just like the original, metal frame with neoprene molded at the mating edges for a good seal. I see now that the delivery time is quoted as 1 to 2 months, but my kit arrived in about 10 days from Torrance, CA, a nearby suburb of Los Angeles. The lead time probably depends on production run schedules at Aisin. I am very pleased with this purchase.

Worked fine. Found that my car had AISIN WP after opening. Any how I replaced TB with original Honda one for $45. Still worth it for all the other components. I'll update the review if anything goes wrong over the next two years while I keep the car.
