    Default cooling temp sending unit problem

    I have a 2000 Saturn SL1 1.9L SOHC, in the manual fig. 8.3 it shows the CTS as being near the intake hose to the engine. But on my engine there is no such sensor location.

    Saturn did make more than one engine type, and this manual does not show all types, even though it states its for '91 to '02.

    Anyway, can someone help with this?? I think that the sensor is further lower on the block, I found a sensor with yellow & black wires coming from it. I tried to remove the sensor connector but it would not budge.

    Hi dexcaliber,

    Look again on the left end of the cylinder head, but down a little lower and to the rear. I checked with a couple of professional-level information services, and this is the only location that was given.

    Hope this helps.
