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.

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.

Water pump
The fitment is the same as original and so its functionality. This is better than what was on my truck. The impeller on this is metal compared to the plaster was on it before.

OK good but/ missing gasket still- really? and then order Gasket-get FIPG-
OK good but...big but!---missing pictured item consistently!- 100 reviews - 65% say "no square water Punp gasket shipped" w their Ausin Timmg bsmt kit (TKT-021)- yes, technically it is not a pkg. problembut speaks to (imh) lackadaisical attitude on partt of Prime & the vendor ---given the reviews are good and perhaps no loud protests as people try to be balanced and it's well PE Ed item even w/o gasket but I needed it and now it's late to order additional part! .It is still a severe error of omission!--overlooking vendor pictured item in this kit is misleading, at best, and dishonest when it happens repeatedly (with still no correction of picture requires call to customer service as yone reviewer notes ) !-Top helpful verified reviewer pictures shows "water pump gasket missing!"A 4-5 star review doesn't mean "ignore issue"means fix it! So...now need to pay. $15 & wait for gasket, delay repair, as its safety issue!- update got gaske and dogs sebt FIPG ! man twice bitten will ask Brzos rouse FIPG to repair his underwear!if FIPG is a gasket plz tell me by its in picture.. maybe mechanics no FIPG works but I prefer to get parts I pay for.Ordered knowing they might omit part -but was surprised that it's a $14 part- no $14 FIPG tube - what gall! not this vendor so now I have two gripes Love Amazon but need to keep serious kits like this complete or spell out why it's not needed!Update-so the mechanic installed this kit with timing belt water pump and Stent Thermostat 14128 and serpentine belt, and used the "Gastket' that I had to rush to get on time and pay extra 15 bucks (thanks Amazon C.S. for at least paying for expedited shipping but I was non plussedd after talking to you and you not realizing that the so called pirctured missing gasket I thought I was getting was in fact simply FIPG w which my mechanic happily used without complaint-nor saying he preferred the physical gasket-yet back of my mind will always be wondering will the FIPG leak given its NOT the specified part--many far more mechanically inclined than I reviewers say FIPG is same or in couple cases preferred others said on Sequoia its not recommended yet on my LEXUS GX470 2004 it is specified as the pictured smaller gasket that the Obsessive Compulsive in me can not get past it being pictured and NOT IN KIT! I am still miffed that supplier or top notch kids by Toyota's OEM manufacturer AISIN sends all these correct parts yet leaves out a key item-that cost $!5 for FIPG or maybe more if I was smarter and had figured how to get the pictured gasket-I suppose had I griped as a couple of you did and been able to wait for the missing part Amazon would have forced vendor to send it to me--or let me return whole kit then send new one with gasket but I suspect given FIPG can be used and it works-but Toyota is pretty good company and I say they made gasket for reason--if some models its not great fit due to varying fit tolerances then say so and list a kit with it and without it but at least if FIPG is needed say so or put in in with kit as its not something one needs to rush to get when indy mechanic giving me good deal has set aside half a day to do this big job at a price that is half or less the dealer price--so that is it--still leaving at 4 stars-maybe in a year will change it to 5--dont know how or maybe Id make it 4.5 but the gasket is getting a 2 star review at best for not picturing tube of FIPG! SUV running like dream, gas mileage seems slightly up-maybe due more to oil change, but its still a pig with tops 20 mpg combined--now I need a french fry grease converter kit to get me to run on McDs oil for free or some other stuff like Mr. William Nelson PHD in country music has on h is tour bus! KOT!!

Nice!
Great price. Looked 100% legit and genuine as described when I reviewed the kit + my Land Cruiser specialist shop did not say anything to the contrary either. Wish I didn't have to pay the man to do the timing belt job for our 2004 LC (200-series), but low kit pricing made it slightly more OK.

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!
