I bought a 1997 XJ in the fall of last year. Then the head gasket blew with no indication from the temp gauge. Only after I shut off the vehicle and turned it back on did it read in the red. Got it all fixed and because of that issue I was going to place an additional sensor in the upper radiator hose with a second gauge in the cab. However, my buddy that fixed my head gasket told me my head has a second location in the rear and that the head must have been swapped at some point with an older model.
My question is can I use that location at the back of the head as a second coolant temp sensor like I would with the location in the radiator hose?
