Thermostat Mahle or Duralast

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.

Duralast is ok. Does not have to be OEM. It will work just as good

I've used Autozone's Duralast thermostats without issue on my old Integra.

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.

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.

I’ve been using Germany-made Mahle thermostat for years. Now it throws a code that the heater doesn’t work (so it won’t open electrically, but mechanically it is working just fine), but no leaks.

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.

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

I'd advise taking that Duralast thermostat out and installing either an OEM unit or a unit from a trusted brand (such as Stant). If the Duralast gets stuck in a closed position, the SUV will overheat. If it gets stuck in an open position, the engine won't reach operating temp, and you'll have issues such as running rich. Duralast has a nickname we techs refer to: Duracrap or Dura-doesn't-last.
