im new in this forum, and i know there is alot of old post about this heating problem, but mine is a little bit different
A few days ago i bought this mini cooper jcw 2003 and the car is running perfekt, everything was working just fine until it got night and the temperature was falling, then i turn on the heater and it was blowing cold air.
then i went to the mechanic he said it was the thermostat.
he changed the thermostat and also bleed the system. still no heat!
next thing he said, it must be the head gasket, but there was no oil in the water, no water in the oil. no smoke out of the exhaust.
when the car is driving on the highway for alonger period, then the heater is blowing a small amount of semi hot air out but it gets cold within a few minutes.
so my question is :
should i change the Head gasket or do you have any idea what might be the problem ?
