I installed a Fail-Safe thermastat.
In 2 weeks, the thermostat malfunctioned, it stated in locked position. My car was not overheat or near overheat that may damage the thermostat.
I called the Motorad company & they denied their "life time warrantee".
Just want to lead you guys know not to buy their substandard product & don't trust their life time warrantee!
It's supposed to be a fail-safe...if your thermostat gets stuck, they're supposed to get stuck open, so coolant still flows. Regular thermostats can get stuck open or closed...closed and you over heat. The fail-safe ones I tried about a year ago failed miserably (2 different t-stats) and locked closed. It's all a hoax, I say. Went back to the el-cheapo t-stat and haven't had a problem since.
Fail-Safe thermostats (made by motorad) are the "premium" brand that are sold at all the Autozone store. They highly recommended them & cost more too.
We need to pass on the message so there will be no more victims from this fail-safe crap!
I dont see the point of this given the fail rate of normal thermostats.

I used a fail safe thermostat once & it failed. It also stuck open with normal engine temps. When winter came along I had no heat. The only thing I recommend is if you open up a coolant system to change parts, I find replacing the thermostat is a good thing.
I also had one stick open with only moderately elevated engine temp, will never buy another one.

I too just bought one, it failed on me also. Wish I had seen this before purchasing it. It never even got over 215. Drove to work at 160degrees. At idle it will not get over 130. Guess im going back to vatozone to get them to give me a new one and a gasket.
Just had one crap out on me, within 1 day. In Florida it's hot. So I thought I'd use a 180 fail-safe. Vehicles running around 220 and naturally it "failed safely" and is not forever in the opened position. Which I assume means you'll never get heat because nothings closed to force fluid into the heater hoses.
