Hey folks,

Just picked up an 06 E320 CDI, 296k miles.

Driving it home noticed it seemed like wasnt getting much out of the cabin heat, seemed like I couldnt get it to blow hot.

Noticed the engine temp indicator seemed low to me. About what temp Celsius should it be when up to full operating temp? It was hovering around 40. to 50. Celsius

Wondering if there is a possibility of stuck open engine cooling thermostat.

Thanks!
