I bought a 98 vic that had a motor out of a 98 Cobra. When I bought the car that motor was bad so I got one with low miles out of a wrecked thunderbird(98) and transplanted it in this car. It runs great and gets 23mpg but the issue I am having is the fan doesn't always come on when I think it should. The high and low does work when it does come on. On the bad motor I pulled out, it had a sensor that looks like a temp sensor screwed into the block,under the intake,drivers side, right below where the head bolts to the block. I unscrewed it and just layed it somwhere to where the block can heat up the plug till I figure out what it is what I should do. Soooo heres my question, On these two motors. Where is the sensor that runs the cooling fan and wheres the sensor that runs the temp gage? Or does one sensor run the gage and fan? And does any one have pictures so I know exactly what I am looking at? Sorry for the long post and thanks for any and all help!
