Hi guys,
I was wondering if anyone know how many coolant temp. sensors there are...
I'm replacing my radiator and thermostat and figured I would replace the sensors as well... I know there is the single wire sensor for the gauge and I thought there was only one more. But when I was looking I found one on the right side (to the right of the distributor) and one almost straight back from the gauge sensor... does anyone know what those other two sensors are? I mean which is which? I know one is the temp sensor for the ecu...

Thanks!

The single wire sensor on the front driver side is the temp sensor for the guage. The sensor directly behind it is the Air Charge Temp sensor (ACT).

On the passenger side front, the temp sensor for the ecu is in the hard coolant lines, right next to the fuel rail connections.

This will help.
