I have a 2006 toyota tundra SRT 4.7 need to replace the belt and was looking at the complete kit, what is the best choice
Hi What brands are the timing belt and water pump? I assume timing belt is Mitsubishi, and water pump is Aisin, but the info is not in description.
Will this kit work with my 2004 4.7l v8 4runner? also, is this a complete kit with everything included?
It is recommended on the 2001 Tundra to change the timing belt at 75k miles and not to extend beyond 100k miles. I am interested in why the water pump and the timing belt are in one kit. Does the water pump commonly fail at mileages similar to the timing belt?

Highly recommend

After a journey of blood, sweat, bruises and tears, this water pump and timing belt kit fit perfectly on a 2002 toyota sequoia and saved me a ton of money in repairs! Good quality parts.

Exceptional Timing Belt Kit

Exceptional TB kit .... you will not go wrong here. TB maintenance was done on 2004 Sequoia with 187,000 miles, on what appeared to be the original timing belt, water pump, and TB components. Tensioner was NTN, same as factory, both idler and tensioner bearings matched the OEM brand, and water pump appeared identical to OEM pump. Belt was Mitsubishi. Both rubber water pump & thermostat housing O-rings are included as well. Very complete kit, and OEM quality without paying dealer prices. I highly recommend this TB kit.A few thoughts on this job that you might want to consider if you're diving in for the first time ... consider replacing thermostat while everything is apart. The same goes for the serpentine belt, belt tensioner, and idler bearing. On this job, the cooling fan bracket caught me by surprise, as I'd not considered replacing that. It felt fine ... but on higher mileage vehicles, probably not a bad idea to consider replacing while everything is apart. This is a very labor intense TB job. And if you don't have the proper tool for removing the harmonic balancer --- don't scrimp now. Buy the holder! Made a near impossible job without the tool a literal 5 minute job. When you're done with the TB job, feel good knowing you've saved yourself about $700-$900 in dealer labor charges!

Best value for Toyota OEM parts, period.

Hands down, the best timing belt/water pump kit you can buy for your Toyota/Lexus V8 engine.I have a 2006 4Runner with the 2UZ-FE engine and it's getting ready to roll over 200,000 miles. At 100K miles, I took it to the dealer (I know, don't shoot me) and they charged me a tidy $1,400 to change the timing belt and water pump. For 170 bucks and a day's worth of my (or your) time, this kit will save a lot of money.I'm one of those guys that like to use Toyota OEM parts, but not pay Toyota dealer prices. I checked quite a few online stores that sold Toyota OEM parts, and purchased separately, the best price I could get for everything included in this kit was about $400. This is a great--I mean fantastic--price for everything that you need to perform this service.Both bearings are Koyo branded (the same used by Toyota), the water pump is Aisin (same used by Toyota), the hydraulic tensioner is NTN (same used by Toyota) and the timing belt is Mitsuboshi....you guessed it, same as used by Toyota. Everything you see in the picture is included EXCEPT for the square gasket that fits to the top of the water pump. Honestly, I didn't even know this gasket existed since the Toyota manual calls for using FIPG (Form In Place Gasket) for this seal. FIPG is essentially the squeeze type gasket stuff out of a tube. You can get it on Amazon Genuine Toyota Fluid 00295-00103 Formed-in-Place Oil Pan Gasket - 3 oz. TubeThis kit even includes a very nice booklet with directions on how to perform the timing belt replacement. But, I'm guessing if you're buying this kit, you're either giving it to your local mechanic or you're doing it yourself and you've already spent lots of time on the web researching how to do it. Or you're a cracker jack mechanic and you can do it with your eyes closed, with one arm tied behind your back.I haven't used my kit yet, but I know a lot of people looking at this are very curious to know what exactly is included in the kit so I wanted to make sure I at least let everyone know what was in mine. I've included pictures as well for your viewing pleasure.When I do perform this service, I'll post a follow up review and let you know how things go.UPDATE: Sept 2022.Procrastinate much? I just installed this kit 7 years after purchase. The only negative comment I have is the tensioner didn’t fit as well as the original on the vehicle. When tightened down, it was binding and not allowing the tensioner to freely move. Easy fix, I just took the pulley off the new tensioner and placed it on the old one.I would definitely but this kit again. For what it’s worth, my timing belt had 200k miles on it when I replaced it and it literally looked just as good as the new one I installed. That Mitsuboshi is one heckuva good timing belt!

Fits a 2003 Toyota Sequoia.

Good quality kit. Fit a 2003 Toyota Sequoia. I would suggest watching a few YouTube videos and take your time. The only knock I have is that the crank marking on the timing belt didn’t align with mark on the crank. The mark on the belt and the crank was both in the valley, so no matter how the belt went on I was a half tooth off. I aligned the marks on the cams perfectly with the arrows pointing to the front, and the crank mark on the belt was on the passenger side of the crank mark. Everything is running fine. I added a tube of silicone for the water pump housing ( not the pump, it has its own gasket), a new thermostat and gasket, and you’ll need a tool to hold the crank for final torquing of the crank bolt.

Great OEM Toyota parts for low price!

These parts made my timing belt job much cheaper than buying them from Toyota dealer.

OEM quality for 2001 Toyota Tundra 4.7 V8

This was a high quality kit, equivalent to the old stock parts I pulled off a 2001 Toyota Tundra V8. Definitely would use this kit again. You will need to buy some FIPG gasket maker separately for a coolant pipe/thermostat housing.
