normaly my car temp needle stays in the middle, but one day when i was driving for 4 miles, the temp needle went up to 3/4. i was not giving it some kick, i decided to put on the heaters and straight away my temp needle drops back to middle??

anyone ??

sounds like an air lock in the cooling system/heater matrix, always a tricky one if it doesnt happen all the time.

it happens wen the heaters arent used and when thr car is stationairy as soon as the needle goes up i tend to turn the heaters on then all of a sudden the temp gauge drops to half???????????
