Hi

My punto heater is blowing hot, then cold air, and the temperature rises to about half way, when the fan cuts in and lowers it again.

I had the same problem last year, but it was overheating badly and the fan didnt cut in. I had new water pump, new radiator and thermostat which did not solve the problem and it turned out to be head gasket which was replaced. cost a fortune last year.

Now its happening again, but the temp does not go further than halfway. Any ideas anyone?? It cant possibly be the head gasket again 8 months after a new one could it??
