I own a 97 Olds cutlass with the 3.1L v6, the previous owner of which I bought this fine car from had changed the engine temp sensor at least a couple times in hopes to fix the temp gauge on the dash. I would like to know if there are multiple temp sensors on the engine block and if so, I would like to know the locations of them. I cannot seem to find anything as far as temp sensor locations online and I'm not looking to buy a chiltons manual for this car at this time. Any help would be greatly appreciated.
