Well here is the deal, I just had the head gasket replaced on my 86 n/a and I drove the car down to Flordia to live. I was driving one night and realized me tempreature gauge was rising and knew immediatly to shut the car off and not drive it at all but in the process of parking the car the engine light and the battery light came on and never went off untill I unpluged the negative battery cable.I checked my dionos codes and none of the codes were related to the cooling system except for the code that stated the a/c is on (wich it wasn't because I don't have a/c compressor on this engine) Well after the car sat for a month I did a full tune up and bleed the cooling system correctly and let the car completly warm up for about 35 mins. NOw im stuck with a bouncing temp gauge any ideas or help please!!
