Thermostat Wahler or OEM Nissan

I got a Wahler thermostat once who was the OEM maker for MB, the only difference between the Wahler and the old MB one was that there was a spot where the MB logo was, on the Wahler one that logo was gone, looks like it was there, but someone with an angle grinder scratched out the MB logo so it probably came off the same line that made the MB part.

I have had a car not bleed properly/ run hot (but not overheat) only when using the wrong thermostat. Replacing it with Wahler fixed the issue.

A proper Wahler thermostat is what solved it.

I just put a new Waller in every 8 to 10 years when it comes time to redo the cooling system. Never had a leaking or stuck thermostat but we do live in Southern California, so I think things tend to last longer Here

I've had a Wahler fitted for 1.5yrs and everything's ok so far

Since going with the OEM thermostat, my temp gauge has stayed pinned just below the middle of the gauge, even towing campers and heavy loads on hot days.

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).

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