'00 X5 4.4i cooling system
Hey Gang, Just had some engine work done (timing chain and guides) since the reassembly my temp gage is normal but I have coolant coming out of my over flow cap. Pressure test is fine. No codes. Thought it could be an air bubble in the top of the rad due to improper fill. Have been told by a BMW Buff that it could be a sensor. Apparently there is 2 sensors for the rad 1 that is read by the computer the other not but can affect the cooling system in this manner. Has anyone heard of this? or maybe some insight? Thanks.
