Just so happens my clearance thermostat is a Motorad which has the VW/Audi p/n cast on the housing!
If you want hotter with a thermostat the exact same shape as the genuine VW version, get the Mahle TX1392D. 92 C opening temperature. Keeps the engine warmer and you get a little better fuel economy.
I replaced my newly bought Wahler t-stat with my old Mahle but drilled. Temps stays 80-87c.
MAHLE was the last thermostat put in her… no issues happened since then to this day, continues to runs fine, no fluctuations in gauge, or overheating. The dealership even started to have that issue with other customers until we switch to Mahle, solve all thermostat issues.
The Mahle thermostat arrived today along with all the other bits I think I need to put the car back together. The problem is that the new one doesn't quite match the old one.
I tried a parts store Motorad, failed. Tried a Napa gold stat that turned out to be repackaged Motorad, failed.
Every 6-7 months the cheap garbage scam of a brand Motorrad remains to be the only available thermostat I can access. I do the temp gun test, I verify my sensors are correct. I burp the cooling system. Everything. I’ve gotten so good at the job now. Every brand of thermostat I’ve tried in Canada is a Reboxed Motorrad. Premium to Economy. 7$-25 they’re all the stupid same. Parts source, Gates , Napa , Autovalue , “mopar” from my dealer. All Motorrad at different prices. I know of 2 they make, the standard oe 195 which is usually economy line. And the fail safe one they make. Both have catastrophic failures, either get stuck open, spring blows apart. Usually after 6-7 months they stop working entirely or the thing slowly stops letting the Jeep get to temp and I dread reliving the Motorrad Groundhog Day effect. It’s a garbage thermostat. People have argued with me that they make OEM equivalent parts and they never have issues but I’ve had nothing but issues.
I had to replace mine again after 6 months.
Just not Motorad--unless you want to replace it again in 6 months
In regards to replacing the thermostat, Id stay away from Mahle/Behr. I just ran through two that stuck open, so far the Borg and Warner from FCP can actually hold temp @ -19C, which the Mahles could not at -10C.
