GREAT BUT 👍
I have been a shade tree mechanic since 14 years old, at 67 years old Toyota wanted $1600 to change out my timing belt and all these components. So I bought this and did it myself and saved a lot of money, thanks to these parts and YouTube !!!!!

Great kit!
Awesome and complete kit! Direct fit for my 2004 Sequoia, just make sure you get gasket maker for the water pump as that's no included.

Fit my 2001 Toyota Sequoia, legit part
I installed this Aisin timing belt kit since December 2023 ( two years ago) and no issues on my 2001 Toyota Sequoia. This product is a legit Aisin with the halogram sticker.

No timing belt sticker as described
Excellent kit. It's what OEM use. Only problem was that it didn't have the Aisin Timing Belt Sticker as it claimed in the description. It had everything else. I looked all over that box for the sticker.

Everything necessary fof timing belt and water pump change. The only thing to remember is that you should also buy a new replacement serpentine belt for the alternator, if you wsng to do a proper job.

Yes this is indeed genuine Toyota components. Just didn't have the Toyota's dealer markup cost. Installed over 20k km ago. Kit was excellent fitment. As to be expected. Good instructions. Installed it myself. It's a weekend long project to do this job yourself. My brother assisted and we knocked it out of the park. Kit dues not include everything you'll need to do this service, you'll need some sealants not included. No fault there just a warning that you need to research before doing this job. Toyota designated specific RTV Silicone engine sealants will also need to be acquired to do this service job. That said, everything in this kit is Toyota quality and fit and finish is "as factory". 4.7l V8 VVTI 2005 Toyota 4Runner I'll be ordering this again when it's due for the next service. My brother has done about ten of these now on various Toyota's and those is there kit her recommended me to purchase. 🤘👍❤️👌

Fit the Toyota tundra 2007 perfectly. Very nice kit Asian is also majority owned by Toyota so you are getting oem product. Skip the dealer if you need this kit.

This Aisin package represents unbelievably great value. These are the very same items sold individually by Toyota dealers, ( in repackaged red and white Toyota livery ) I purchased these very same items from a Toyota dealer, here in Australia eleven years ago for over $600.00 Add free postage from the U.S.A. and this represents fantastic value, unmatched anywhere here in Oz.
