Thermostat Wahler or MotoRad

Big fan of the Motorad SNN-2000-195. Works great.

Just so happens my clearance thermostat is a Motorad which has the VW/Audi p/n cast on the housing!

Spend slightly extra and get a quality OEM Wahler thermostat.

Got the Wahler on my 2008/2011 and it was identical to the MB part except the area that had the MB logo on the original one was ground out.

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.

Had a Motorad Fail Safe a few years ago and it was a POS.

Tried a Gates from RockAuto and it was a Motorad in the box. Installed it anyway, it seemed to hold the temp *lower* than the 170 Stant did, and my engine cooled all the way down to cold when I went down a long grade.

Thermostat was ALSO replaced when the water pump was, with a Wahler unit. Guess I got 10k miles out of it?

I tried a parts store Motorad, failed. Tried a Napa gold stat that turned out to be repackaged Motorad, failed.
