⭐⭐⭐⭐⭐ 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.

Everything thing you need in one package.
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.

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. problem but 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!!

Quality items in the kit, made in Japan and not China so it fit like OEM. Almost twice the cost of the knock off Chinese ones but worth it IMO, sometimes it better to pay more and have to do it once.

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.

Great kit almost comes with everything, but you need to know you have to buy the thermostat housing gasket if you want to do it with the timing belt and water pump job.
