: i just fitted a new a new radiator on my M3 but it is still overheating.the fan is working a high speed. it overheats eratically either in traffic or highway. coolant is not missing so i guess the head gasket should be alright. anyone has any info about this since i paid so much money at the dealership and still the problem was not fixed. i would apreciate anyones advice.
It sounds like you may have a airlock in your cooling system. Try and bleeding the system and see if this helps. Also check and see if they have fitted the correct thermostat!
