i found a coolant sensor on my 91 gt on the lower intake under neath the egr valve but nothing connected to it and cant find a pigtail for it anywere if somebody can ell me were the pigtail is in the harness would be greatly appreciated
Coolant flow at the back of the intake can be compromised. I would simply look for the stock gauge sender and ECT in their stock locations. If you have those and you don't have an aftermarket gauge or electric fan, that sensor is probably left over from a PO's modifications.
ya i got an aftermarket gauge on the drivers front location and i got the ect sender on the passenger so who the heck knows y that one is there. but thanks for all the help
When i installed my autometer temp gauge in the stock location, i moved my factory one to the rear of the intake just to keep it functional (backup if anything).
It reads slightly cooler, but at least it's not a dead gauge. I personally am not a fan of cars with aftermarket gauges and the factory gauges all sitting on 0 when the car is running.
