I went and bought a coolant temp sensor for the ECU, where is it located? I thought it was on the right side of the engine just below where a coolant hose runs to the engine, near the front. I have a Euro Haynes manual, and there is a pic, but the sensor that I bought looks smaller than what appears to go in the spot I described. Car is a 1990 90 SOHC....

well no knowing if its a 4 5 or 6 i can give u info on the 4cyls. there are 3 sensors. comming off the head is fitting with 2 sensors one for the temp gauge the other for the ecu fuel system. there is also one on the radaitor bottom drivers side that goes to the ecu and fan. hope this helps

It's the 5 cylinder. Is It closer to the front of the car or towards the cabin? In my Haynes it's closer to the front. I guess that I'll just have to start pulling out sensors, and match it to the one I bought. Does anybody have a part number for it? To make sure I got the right one. There where 2 different sensors available.

It's on the top of the coolant snout on the front of the head (driver's side)

Follow the upper radiator hose to where it meets the engine, I think there are two sensors there.
Another sensor is located at the back of the engine block right under the battery tray location(white 2-pin).

The sensor that I got was gold, 2 wires, appears to be a sold piece of brass, oir similar looking material.
