Perfect Fit 2004 4Runner V6
I have 2004 4Runner SR5 V6. Needed to replace thermostat and saw they are sold as a set. Perfect fit, good gasket, no leaks, looks like OEM. Great price easy install, quality part. Tom S

Thermostat for a V-6 Toyota Tacoma
I bought this thermostat for my '05 Toyota Tacoma, 1GR-FE motor. It replaced a Toyota brand thermostat. So far, so good; I'm very satisfied with this thermostat. My engine was overheated, I believe the stock thermostat was malfunctioning. This job was relatively simple, but I did lose 2/3 stock nuts that hold the thermostat in place. I had to pick up M6-1.0 nuts and washers from Lowe's. I would definitely buy this AISIN THT-003 thermostat again.

Oem fit
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

AISIN quality
Have had it for about a month and so far it has done its job. Quality seems nice, looked just like my denso one I pulled off during my coolant system overhaul. I also got the Aisin fan clutch for a 2004 4runner and it seems to be working good as well if anyone was curious

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.
