AISIN GENUINE TKT-025 Engine Timing Belt Kit with Water Pump - Compatible with Select Toyota 4Runner, T100, Tacoma, Tundra

OEM replacement parts that fit and last.

This is a great kit on a gen3 4Runner. The last kit installed was also an Aisin, and it lasted 120K, (40K past due) not something I recommend. The kit even included a thermostat gasket. Only things missing could be the crank and cam seals, but not everyone replaces those. Everything fit, nothing leaks, best price. I just wish I had done this during warmer weather.

For those concerned about fakes/forgeries of OEM parts, these parts are all in original packaging/boxing inside the Aisin box, looks legit with all the markings on the bearing seals and packaging. Mitsubishi belt, Koyo/NSK roller bearings, Aisin metal waterpump/tensioner, no nameplate on the bonded gasket but it looks identical to my factory gasket that has the gasket bonded into a metal frame so no need for RTV/FIPG. Like others said the waterpump even shows where the OE Toyota name cast into it has been ground off for resale under the Aisin brand. Comes with an Alldata work packet thats helpful for DIYer's but made for mechanics (lol at the 2.5hr flat-rate expected turnaround on this job). My only issue is the original Aisin box wasn't in anything else from Amazon and just opens right up without any seal break so it's possible to have the whole box dumped out before it even reaches you. At least with Amazon returns are still easy but I seemed to have everything shown in the pics and install went well.

Amazing kit! Just installed this kit on my 1998 4Runner everything fits so perfect not like some Chinese garbage kits that you can tell right away are made of poor quality material and the gasket is paper not steel like the one in this kit for people who dont know Aisin is the OE supplier for Toyota parts 100% highly recommend this kit!

I ordered this for my 2001 Tacoma EXT Cab TRD. I don't have much mechanic skills so I took my truck and this box full of goodies to my local mechanic. When I told him I ordered a timing belt kit online he told me I shouldn't have done that and should have ordered through him for a better deal and quality parts. I told him how much I paid and he was even more worried about the quality. Fast-forward a couple days and he called to say my truck was ready. He told me he was surprised to see all the parts were geniune Toyota OEM parts. (Belts say "Made in USA right on them") He told me he was also surprised at how everything he needed to update the area around the timing belt was also included (waterpump etc..). One thing he did suggest and later bought for me was all new "drive belts", he said they were bad and he put on new ones while doing everything else. So that is the only thing you may want to consider. That and mine came with a thermostat in this kit, but now I am not seeing it listed, which is weird. And finally, while I wish I was talented enough to do this myself, I am very glad for this kit saving me a lot of money for parts. Dealership was going to charge $800 to $1000 for the parts and labor. This kit and labor from my neighborhood mechanic came to $450 total. Not bad!!!

This is my second time to buy this kit (or at least one with the same exact parts). They are great parts. Same as stock and I did mine for the first time at 220k miles because the truck ate the AC drive belt and since I was in that deep anyway I did it all. Only reason I am having to buy it this time around is because my mechanic who swapped in my JDM 5VZ FE used parts store junk when changing the timing belt and water pump. It was leaking undetected for an unknown amount of time, but I noticed it around 50,000 miles later because I was overheating from the coolant loss. Do not use cheap, poorly-made parts that are that labor intensive to change, ever. To top it off, the parts store crap I didn't know I was buying until after the work was done probably costed me more than getting OE parts on Amazon. Unfortunately this review only gets 4 stars because my water pump gasket was warped upon arrival. While I know this should not affect its function after being straightened out, that part is the entire reason I am buying the kit this time and it came less than perfect. All that had to be done was store it flat under the water pump, but they placed it on the side of the box with the bearings and they shifted around and bent the gasket. UPS probably was not extremely careful handling the box, but that should always be considered as a possibility when packaging multiple items in one box.

Had this installed for over a year now, working great, no issues

Very nice same as genuine toyota timing belt kit. Asin is the manufacturer of water pump and idler pulleys and Mitsubishi is the brand of the timing belt. All are OEM just not branded for Toyota. For a 2001-2004 Tacoma, take out the radiator, rent or buy the special tools that are separate.... trust me on this. Make sure to match the notches and once the belt is on, turn the crankshaft twice to release the slack built up that you don’t notice is there. Trust me, if you don’t your marks will not match up and you will jump half a tooth and you’ll have to take all back apart. Make sure you fill the radiator and leave the cap off when you restart it. Keep filling it up as it warms up. If not you’ll only have about 1/3 of the coolant and very bad. Also I would buy the 3 drive belts and the gates brand drive belt tension took to measure the tightness of the belts.

I got this kit for my 1999 Toyota landcruiser prado that shares the same 5vze-fe as the 4Runners and tacomas. Came with everything except for a thermostat which was cheap enough to buy an oem one for $50. Everything was well put together and made very well; it was nice to see the idler pulley and tensioner pulley have stamping saying made in Japan. For you prado owners make sure yours has a transmission cooler; I luckily did some research and found out mine doesn’t have one so I had to go out and buy the Aisin water pump without the fitting that sticks out so keep that in mind. An awesome kit overall

fit my tacoma 2002 3.4l. came with everything. Nice kit. My hydraulic tensioner needed to be replaced so i bought this kit, good thing i did because like i said i found that it needed to be replaced. Good kit and good parts.

This is an excellent product,uses all oem parts and the price is right.This fit my 2000 Toyota 4Runner perfect and would buy again.Thanks to Amazon for the great service

Installed two of these and they come with everything. Very good quality parts. Worth getting a thermostat to install with this too.

Used 4Runner with 430000km had sticker for timing belt replacement 20years before at 160000km belt was age cracked and one pulley sounded dry but spun fine and not loose. This kit looks to be the exact same one that was in it very happy. Great price too
