Thermostat Mahle or MISHIMOTO

Mahle is the OE replacement for the thermostat, the Chrysler logo is on the part but sanded down. Autozone sells them with PT# TI23695 I just replaced mine last weekend.

It’s now got an 85°c Mishimoto thermostat. Took it out today and got it up to temp and did multiple 0-85mph pulls. The new thermostat opens at 85°C/185°F. Under load the coolant never registered above 197°F!!!!

Mishimoto has a great thermostat plus it has a lifetime warranty

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.

Mahle is an OEM supplier and is on stock in Amazon.

Thermostat and temp sensor were just replaced with OE Mahle/Behr. P0128 showed up after car didn’t get up to temp. Heat is slightly affected until reaches operating temp.

Last week changed the thermostat on my 1.9 tdi 66kW to a Mahle TX 15 87D (11€), it was fine for the first two days, then the temps started dropping again.

1st Mahle. The engine only reaches up to 65 degrees and it drops further if I drive under 2000RPMs on highway for example or turn on the heating.

Forget about the Mishimoto thermostat. The OEM thermostat is way more reliable and does the job.

car in winter cant even reach optimal temperature in idle, reaches optimal temperature only uphills on RPMS higher thatn 2500
