Ive been trying to diagnose my idle/stalling problem, and just thought of something. There is a hole for a sensor to go on my left (edit: Right) head. I found a melter sensor dangling under the car. What sensor should go here, and does it effect idle? Thanks

 

Coolant temp sensor for the dash gauge.

 

I thought that was the sensor in the driver side head? Or does the car have 2?

 

The drivers side is the left side. On the right side (pass.) head you have a coolant temp. sensor and below that sensor is your knock sensor.

 

I'm sorry. I have the sensor in on the driver side, but the pass side is missing its sensor. So its the coolant temp im missing? I have a temp readout on my gauges...

 

The pass side sensor is actually a temp switch that controls operation of the radiator fans. Won't affect idle but should be fixed so that your fans come on with engine temp.

 

Do you know what the name of this switch is so I can buy a new one?

 

Rock auto calls it a cooling fan controller. Any auto parts store should have it, just ask for a cooling fan switch. Just curious, but how are you runnung your engine with a hole in the head where this switch goes without spewing coolant all over?

 

I'm really not sure, but I'm not.

I know the PO jump wired the fans so they both come on at the same time, but I figure I'll pick up the switch anyway. thanks!

 

thats interesting.... I'm missing them both... huh
