i need some help in the a similar case but my car is a 92 318i automatic
i was driving home and i notice the temp slightly goes up then it reach the red so i pulled over and let it sit till cool off and drove home carefully.. Then it happen again when i was in traffic so i had to pull over again. So i find a quick place to park bought some coolant just to get by i know im suspose to use bmw coolant or some sort i hope i didnt do any damage so after the temp cool down enough to open the coolant bottle i topped her off and close the cap it seem fairly low. She drove around find then a few days later i check and the coolant amount drop again so i kept topping her off no time to see any shop yet..
Some say it might be fan clutch, some say themo, some say waterpump which one is it really.. I dont want to waste time and money changing the wrong parts.. If anyone had experienced the same thing please tell me.. thnx ahead of time
For the heating keep in mind what you said, you are having coolant losses.
First go and try to find where is the coolant leaking at, ive seen that most of the time a coolant leak begins at the heater core inside of the car, and this coolant leaks trought the ac, heater housing drain.
After you fixed you coolant loss mistery, go and check you fan, check both, the electrical and mechanical, check to make sure you electrical fan sensor thermostat is actually working. Then i would go and check the water pump and then engine coolant thermostat..
Keep in mind that BMW engines are high performance engines that require good cooling systems, if the system is negleted, even on its small details, the engine will bicht.. Own experience with bimmer.
Anyway hiope this helps.
