Owner reviews for thermostat

Independent mechanic noticed leak. Dealership confirmed the thermostat was cracked and leaking. Took a week for parts to arrive. Took a day to repair. All covered under warranty.

The OEM Aisin thermostat opens at 185, staying completely closed until 180 where it can open up partially allowing proper circulation and proper temperature control. The engineers at Nissan designed this cooling system to function in a certain way at very specific temps. ONLY USE THE AISIN 185 OEM thermostat in these trucks.

Bypass thermostat yellow arrow Included with radiator upper hose and you should be able to find the bypass by itself.

The Honda thermostat opened probably 50% more than the aftermarket, so lesson learned there.

Forgot to add I test drove her last night to the store, holy $hit it runs like a beast, if I had to guess it feels like it got 20hp back and idles smooth as a new mk7 no shaking no cel lights just butter, it accelerates much smoother and faster then I ever had it. Such a difference it was amaze balls.

I installed a Wahler thermostat a little over a year ago and it's still holding strong.

I have owned my B6 since new and had the thermostat replaced under Warranty around 36,000 miles, at that point the slow warm up was causing the MIL to illuminate with a error that basically said warm up outside specification.

I just be replaced mine for the low regulating temperature, and the snag seemed to improve, but it will still pop up and the car is slow to hit temp, slower than it was last winter at least.

I replace the thermostat and it is not opening…I have let the car run for over half hour, even went for a short drive, nothing, the thermostat is not opening. I was only able to put half the collant in, and the heater isn’t blowing any heat ( makes actually a weird noise when I change settings) is it possible that a brand new thermostat ( rock auto, Brand is Facet) could be defective?

MotoRad thermostat. Lasted less than 6 months.
