328i cooling system trouble. Symptom: Overheating and gurgling through expansion tank. No heat coming from the heater..both heater hose's hot. Doesn't smoke. Oil is not milky. Fan clutch good. New OEM pump, radiator etc
Replaced the usual and bled system. This has seperate expansion tank and apparently self bleeding...filled it up and watched all bubbles disapper. I still think there is an air lock..hopefully.
I questioned one BMW mechanic - all doom and gloom merchant - He thought there are stripped head bolt threads in the block due to warped head and coolant going into combustion chamber - $5000??
I sure I installed the thermostat in correctly but haven't double checked. Could this cause these symptom's?
I see many other people with many similar problems but with alot of different cause's so can anyone help with this?
