Reviews of Wahler thermostat

I have experienced same with Wahler thermostat.

I’ve replaced it twice and it starts leaking from there in about 2000 miles or so. I’m willing to bet that thermostat is a Wahler brand. They are known to leak like this.

The wahler thermostat is either broken or its too cold where i live cause the car never really gets up to temp (or my temp sensor is broken).

Spend slightly extra and get a quality OEM Wahler thermostat.

The Wahler one's are rubbish. Did the same after my fucking brand new Wahner DID NOT work....

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.

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.

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