Exact fit ! The hardest part was getting that 3rd 10mm nut at the back off/on. Also getting the hose and clamp off/on. Including changing the coolant, the job took about an hour. Temp gauge is now where it should be.

I saved $53 for the exact same OEM part on Amazon, compared to my local auto part store. Amazon is my go to place for genuine & aftermarket parts.

Gave it some time and miles before writing this review. Replace my factory Thermostat at 156,000 miles with this unit and have had no overheating or other issues after about 300 miles. Super easy to change out as its plug and play and does come with a new o-ring as well. Will def buy again when its time to change it out again.

No leaks. It says, TAMA, an OEM supplier instead of Toyota.

Runs slightly cooler than my last one and the plate popped off the plastic guide. Had to use the ole vise to put it back in place but I haven’t had an issue since

Great replacement WITH GASKET for 4runner. Probably OEM at a much cheaper price than dealer.

This part is better than good it's great. The part fit almost considerably more superior than OEM. Worth the money

Brand new product but must be defective because since changing it— I AM GETTING 200KM on a full tank of VPOWER SHELL GAS! That’s not good.The fuel mileage dropped the minute I changed my thermostat. It was fine before that. AISIN, I can change my review to five stars if the replacement you send me works. Please reach out to me.
