We removed thermostat completely as it was getting stuck from the bmw that has cooling problems, changed radiatior, water pump and checked heads
Also check the radiator cap. If the spring in the radiator cap is worn, it is not pressurizing the cooling system properly and therefore it will cause the vehicle to overheat. This is often overlooked and is a cheap repair. Every additional pound above atmospheric pressure that the cooling system is under causes the boiling point of the coolant in the system to raise 3 degrees F if memory serves me correctly. So, if the cap is old it will boil at 212 instead of 230 (for example)-and cause the system to overheat--even though everything else in the system is new/operating perfectly. If this is not your problem you may want to check to see if the cooling system itself is, indeed, holding pressure. You can get a gadget that fits on your radiator from any auto parts store to pressurize the system--after you pressurize it...leave it alone for about 20 minutes and see if it maintains pressure. If it doesnt, you have a leak somewhere. Hooah.
I am having overheating problems with my BMW 316i...The heating in the car has now been working for some time now but about 4 days ago...the car started to overheat...within minutes of starting the car from cold...the temp gauge shoots up to half way and within 7-10 mins its in the red....What could it be???
You need to bleed the system properly, it may be best to take it to a dealer to do as it is quite a process to get all the air out. even when you think you got it right you prob havent. normally takes me anywhere from 15mins to 1 hour to get right.
What if i change the radiator and fuel pump ??
Thank

check if the water is circulating as you might have a blockage in the header tank. this can be checked by opening the radiator cap and check if the water is circulating on top.
