## Description

AISIN's Water Pump/Timing Belt Service Kit is the common-sense combo as these components should always be replaced at the same time regardless of which component needs replacement. The work involved in replacing one of these components is about the same as replacing all of them - save yourself time and money in the long run by replacing all components at the same time. AISIN's kit includes OE matched components, just like the ones your vehicle left the assembly line with - no generic parts here, just the brand names you know and trust - AISIN, Mitsuboshi, Toyo, NTN, and more. AISIN is the #1 OE manufacturer of water pumps in the world; each pump features an advanced diecast aluminum housing and premium internal components with carbon ceramic seals for superior durability. Kit includes OE matched components: Water Pump, Timing Belt, Tensioner, Pulleys, Gasket, Seals, and Installation Instructions - all packed in one convenient box, ready to install.

Review: ⭐⭐⭐⭐⭐ What can I say — OEM replacement belt kit that really delivers - I installed this AISIN timing belt kit with water pump on my 2UZ‑FE and it went in smoothly, fit perfectly, and all the parts felt like solid OEM quality. Belt tension and tooth profile were spot‑on and the water pump sealed right up without any drama. 💡 Real 2UZ‑FE timing belt tips that matter: • Mark and re‑check timing marks carefully. Align the crank and cam sprocket marks with the belt marks, then rotate the engine at least two full rotations by hand before you torque anything down to make sure everything lines up exactly — if it doesn’t, take it off and try again. • Replace the water pump with the belt kit. The water pump is driven by the timing belt, and letting a worn pump go can shorten the life of your new belt. • Clean all pulley surfaces before install. Wipe oil and coolant off the crank, cam, idler, and water pump pulleys — don’t let contaminants interfere with seating and timing. • Use a torque wrench on key fasteners. Crank pulley, tensioner, and water pump bolts all have specific torque specs — meet them to avoid loosening or over‑stress. This job isn’t always a quick afternoon — getting into the timing cover can be the longest part — but doing it right will save headaches later. If you’re tackling a 2UZ‑FE belt job yourself, this AISIN kit plus these tips make a solid combo that keeps you confident you did it right.
Review: 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 !!!!!

## Questions & Answers

**Q: 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**
A: Hello there.  I have a 2004 TRD 4.7 and am assuming you need to replace the timing belt.  The serpentine belt is much different.  I do not know if they are the same engine so just double check. But Yes, this kit came with everything I needed to change the timing belt along with the water pump and pulleys. The only thing it does not come with is a small tube of gasket sealant for the upper water pump connection.  There isn't a rubber or cork gasket, you have to make one with the proper gasket sealant. Its not difficult, you just squeeze it along the edge and give it 24 hrs but you will definitely need it.  Otherwise the kit is very comprehensive.  I have not had any issues with any of the components and its been 3 or 4 years now.  Good Luck!

**Q: 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.**
A: It's an Aisin kit, so presumably, it's an Aisin water pump (the original, OEM Toyota water pump that came off of my Land Cruiser - I've always been told original Toyota water pumps are made by Aisin - was free of any identifying marks, just like the Aisin pump that came in my TKT-021 kit.  Therefore, since the kit was put together by Aisin and is listed on their website, that lead me to believe it's an Aisin-brand pump.  Also, the timing belt is a Mitsuboshi (yes, that's the correct spelling, so I have to assume there's no connection to Mitsubishi).Bottom line: since this is a kit specified by Aisin on their website, and since it comes with Koyo bearings and an NTN tensioner, I was comfortable Aisin had put together a premium kit, and that's why I chose to go with this kit over any other brand.

**Q: Will this kit work with my 2004 4.7l v8 4runner? also, is this a complete kit with everything included?**
A: This is a complete kit, it has everything you need to do the job. I cant say whether it will fit your 2004. I used this kit on my 2005 Tundra, everthing worked just fine.

**Q: 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?**
A: The reason for changing the water pump during the timing belt job is not water pump failure....  It is because the water pump is behind the timing belt.   It takes about $500 of labor to access the $50 water pump.  As long as you are doing (almost all) of that same labor to access the timing belt, you might as well do the water pump while you have it open.

### ⭐⭐⭐⭐⭐ Everything thing you need in one package.
*by B***. on February 15, 2026*

Don’t forget to order and changeout the sensors can and crankshaft sensors! I watched a YouTube video that walked you through step by step and this product had everything needed to do the job. My only recommendation would be to order the sensors because it would be a major pain to have to go back if one of those fail or are broken during the job.
