Thermostat Wahler or MotoRad

Thermostat is broken or someone changed non-original thermostat.

Those do not work.

Only working (which is also oem) spare part is Motorad Cold climate zone thermostat 5461-82K.

Other does not work. Tested 10+ thermostat on here skandinavia.

I had a wahler thermostat and my temp range was 93-96

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.

I remembered the old thermostat looking like it did, so I waited a few hours to let the engine cool down then swapped the new thermostat for the old one, turned the engine on and no overheating. I've been driving the car as it is for a while now without any problems other than I can't drive long-distance without it running too hot (ex. I drove 4 hours a couple times a year traveling for college, and in the summer the car sometimes would overheat by the time I got to my destination).

Don't get the Motorad that includes the thermostat housing, because that one is junk, and the thermostat housing is not OEM sized.

The MotoradT25 16psi one worked, but don't trust that company either, motorad aftermarket thermostats are terrible and often run too hot - could be your problem.

If your thermostat is from Nappa and says Motorad on it. Then replace it immediately. They are junk and stick closed.

I noticed mine is a "motorad" and it's the cheapest shittiest one and it's been giving me problems.

I had the same issues, less than 4 moths, this brand doesn't work.
