Owner reviews for thermostat

My 2018 Fusion Hybrid SE had a blend door problem and a bad blower motor. After market blower and thermostat, they said to change both, blower motor kept cutting of so I had to use a Ford thermostat. The after market blower seems to be fine now with the OEM thermostat.

I replaced my newly bought Wahler t-stat with my old Mahle but drilled. Temps stays 80-87c.

I had this exact issue with 3 aftermarket thermostats that were opening too early. Bought one from Nissan and my temps went back to normal

I still changed my thermostat to an Aisin unit for peace of mind, so far so good.

a Cummins branded 180 thermostat is the bomb diggity.

I have an 06. Had the same issue. Bought a cheap thermostat which turned out to be no good but acted the same as the old thermostat. Then, I changed EVERYTHING else in the coolant system, lol. Switched to Gates, problem solved.

I have a 1964 Chevy C10 pickup and the thing used to break its thermostats all the time, because it originally had no bypass. I added a bypass and this behavior stopped.

I've replaced my thermostat with a new wahler one and I have the same problem which is that it openes at around 70°C and cools my engine to almost 50°C, from what I understand the thermostat is mechanical and electronically assisted to open faster/wider

I just replaced the original thermostat at 90,000 miles because at highway speeds it would run slightly cold and took a while to warm up from cold. The new wahler replacement takes just as long and will actually run cold intermittently when not on highway. Occasionally it won’t deviate from center on the highway.

My tstat is wahler. People said that it was better than Mahle. But I found it similarly poor.
