Thermostat Wahler or Duralast
In the past and up to several months ago, I’ve always gone with Saleri (Italy) pumps and Wahler (Germany) thermostats for the M54 and have had great results.
Pros: great results
I had a wahler thermostat and my temp range was 93-96
Pros: stable temperature range
Vehicle:
BMW
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.
Pros: OEM quality, identical to original
Duralast is ok. Does not have to be OEM. It will work just as good
Pros: works just as good
My 2007 MKV 2.5 Jetta is still having overheat problems even after changing the tstat to a OEM (Wahler) and the waterpump to one with metal impeller, which works way better than the original.
Pros: metal impeller works better
Cons: still having overheat problems
Vehicle:
Volkswagen Jetta
