Thermostat Mahle or OEM Nissan

yes the part was OEM from nissan

I’ve had so many replacements fail in all my Nissans over the years that I just get an oem one from a dealer. Never had an oem one shit out yet.

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.

Since going with the OEM thermostat, my temp gauge has stayed pinned just below the middle of the gauge, even towing campers and heavy loads on hot days.

Only an OEM Thermostat fixed it.

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.

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

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.
