I have a 98 540i that is starting to overheat. I have replaced water pump,radiator, clutch fan and belt, and hose from radiator to engine. Have not replaced thermostat. I have no heat and my car does not go all the way to the red. Could it be it hasnt been bled properly when the radiator hose was replaced and coolant was replaced? please help. thanks. lisa
Thank-you so much for your help and all the posts. I don't think it was bled properly when I replaced the last hose. But I will do all of the above. Thanks again.
I'd replace the t-stat to complete the cooling overhaul. It might have failed in the "stuck open". There might be a pending code. My X5 has a stuck open t-stat and it takes forever for cabin heat. Pending code is P0128.
stuck open is no heat... stuck close is overheat slowly
