vs
Thermostat Wahler or Motorcraft
Reviews
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
Your thermostat is probably stuck open. Replace it with an OEM Motorcraft version, not aftermarket.
Pros: OEM Motorcraft version
Cons: not aftermarket
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
I replaced the thermostat from a non-OEM to Motorcraft about a month ago, and the only difference has been the speed at which the dial moves from higher temps to its normal positon.
Pros: faster dial movement

I recently changed the thermostat on my dad's car as well, I went with a wahler, and I'm observing the same things.
Cons: observing the same things
I decided to try another thermostat, this time a Wahler and nothing has changed as the car will still not get up to temperature and no hot air.
Cons: car not reaching temperature, no hot air
Vehicle:
BMW
I changed on mine 2-3 months ago with a new one from Wahler/Borg Warner and now it's leaking through the connector.
Cons: leaking through connector
I have experienced same with Wahler thermostat.
Cons: same problem experienced
Vehicle:
BMW
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.
Cons: leaks after 2000 miles
Vehicle:
BMW
Mileage: 3218 km
