Default Oil temperature sensor

Just picked up an 04 SMG to play around with and restore to some glory. Noticed the oil temperature hasnít been reading since I got it. I just did an oil flush and change last weekend, so wonít be doing that again for a while.

Iíve got an oil temp sensor to replace the old one. My understanding is it is by the oil filter housing. Does anyone know when I remove the old sensor, if oil will come out of the hole? If so, I really donít want to do an oil change again.

Default Re: Oil temperature sensor

Oil temp sensor is integral with the level sensor at the bottom of oil pan. That's what you need to replace and the oil has to be drained.

The part you have there goes under the coolant return pipe. It may have other uses on other models, but it's strictly coolant on the E46 M3.

There is an oil pressure switch near the Oil Filter Housing.
