Well, I replaced mine that was behind the engine block... It did not fix it. Now I'm being told it is the one below the radiator. You have to drain the radiator and then replace it. I have heard it is the same sensor. My mechainic says no... I looked at the parts list and it only lists one. Anybody know?

 

I took mine in today to get this fixed. I hope it is what I think it is.

 

what is the car doing that fixing the coolant temp sensor didn't work??

 

When I add temperature on display, clima is more heating to increase temperature which is +7degrees. When I decrease temperature on display, clima is also decreasing heating to temperature +7degrees.
I tested all sensors and flaps and everything is ok. So I do not know, what is wrong.

 

My 3.0 cranks in the mornings and won't start sometimes, then recently the temperature gauge just went all the way down and won't move. This is the CTS correct? Where is it located in my engine?
