I have an e30 325i 1987 bmw . My problem , it is almost overheating . New thermostat installed , new water pump installed . Drive belt tension checked . Drained , flushed coolant refilled with new coolant , and bled system .temp gauge changed and tested , and was reading right .radiator cleaned , no leaks or blockages . Electric fan kicking in when heating up .my last resort , remove the thermostat to get 100% flow and see what happens .also lt is not pressuring out of pressure cap , and there is no leaks . Any other suggestions . I do also live in a very hot climate right on the Tropic of Capricorn , summer here is a killer .
