i am working on a 2000 mystique 2.0 engine and the coolant switch or sensor is not in its place some one has removed it and its danglin there a sensor is plugged in but it does not look like the right one its like a push in type and where it goes looks like it screws in but theres a bolt in that hole where it goes any comments?? also, when the car is driven and shut off it wont start back up for 20 min and sometimes we have to hold the accelerator down for it to start and the idle speed is above the 1 on the rpm any comments there?? thanks.

Hi itehawk4483,

You're going to have to get the proper coolant sensor for your car. It's one of the primary sensors for the fuel injection system; the car won't run properly until you fix this problem.

Your Mystique is covered in Haynes manual no. 36006. You'll find the coolant temperature sensor in Chapter 3, Section 6.
