Coolant temperature sensor install?

Recommended Posts

I need to change the coolant / water temperature sensor in my 2001 911 Turbo tip and wondered if anyone had a writeup on this. Also, would I need to bleed the system after changing it out or would the overflow take care of that?

I actually found a writeup on this in my Boxster Bentley service manual. If anyone could direct me to the location of this sensor it would probably be helpful before I get under there.

Thanks a lot for the picture and diagram. That looks like it is to the left of the pulley's in the rear of the engine... is that right? Is this easier to access from the top or bottom of the engine?

You can only reach it from the top. Look and the oil filter scoop (top black part) and the intake assy (left 3 openings)....

Thanks a ton for the picture... I have a good idea where it is at now. It looks like I will need to remove the airbox, y-pipe and f-hose and possibly more to gain access. I may be getting over my head without a manual to go by.

I'm not even 100% sure that it is the sensor that is bad. When it is very cold out my temp gauge rarely shows all the way up to operating temperature and will give random indicator failures. It seems to work perfectly fine in normal temperatures. I was thinking that replacing the sensor would be a quick and cheap first test.

I never replaced one, but seems to be not that bad. But it is hidden under lots of components...According to your symptoms it is a logic start.... But of course, first, take a good look at the wires attachment to this sensor before removal...
