Perfect fit
Aisin seems to always make quality car parts. This thermostat fit perfectly and will probably last the life of the cruiser. Price was good can't complain

Worth it to get Aisin *doesn't include gasket
My Water Pump started leaking on my 2005 Tundra 4.7 It was intermittent for a while, so I just kept the coolant topped up. It started getting worse, so I started ordering all the parts. Water pump, timing belt, ect. I hooked up my OBD scanner to see the actual temperature of the coolant, and it was hovering from 205 to 210, which is hotter than ideal for sure. After a long and exciting repair job, everything is back together, and 2 weeks later, the coolant temp stays at 186-187 consistently. I replaced the water pump, radiator, timing belt, tensioner and drive belt, also, but it's good to know the new Thermostat is working perfectly. I would venture to guess the old one was not Aisin/Toyota. I myself was tempted to get a cheaper one, as the parts list got bigger. But the old thermostat was definitely worn out. The rubber parts were all misshapen and definitely not sealing, or allowing flow like they should. Same with the radiator cap, the rubber was stretched out. So, while I replaced most of the entire cooling system, and the new thermostats effect difficult to say, it good to know it's working perfectly. The temperature would swing +/- 10 degrees when driving around before, now it maybe moves +/- 2. Side note, as many have said before, the dash temperature guage is not very helpful with these things. During the whole fiasco, it never read anything but right in the middle. If you hit 230 or 240 degrees, I'm sure it would let you know, but at that point things are getting bad. I use a $20 Bluetooth obd scanner I got here on Amazon, and it's been a great investment. Has helped me solve several issues.

Aisin Quality
From the original part manufacturer Aisin. You really can't go wrong with quick shipping from Amazon either. Grade buy!

OEM without dealer pricing
Was half the price as the dealer! Tested it before installation and the settings were on the money. I will rebuy in 4-5 years when it's time to do a full flush again.
