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

Perfect fit on my 04 4runner
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.

Works for 2008 4runner V6
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.

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
