Cooling problems -_- please help.
Hey all i've had cooling problems with my e36 since i got it..water pump failed resulting in a blown head gasket, which i replaced and milled the head and what not..anyways i did the head gasket right..replaced water pump, thermostat, and radiator all within the last 5k miles. So now heres my dilemma. when i get up to operating temperate my upper right hose will have allot of pressure and be very hot, while the lower hose is cold..so i open the bleeder valve to relieve pressure and the heat will start working in the cab for a good amount of time until i come to a stop and idle...sometimes it will start to go over operating temp..so i will pull over and relive pressure, then it goes back to operating temp and is ok..but it seems like i am at a never ending battle with air in my system..so now heres the weird thing to me..while the coolant coming out of the bleeder screw is hot..the expansion tank coolant is still ice cold and has barley any pressure at times, i really don't want it to overheat and blow the head gasket again, someone please tell me what is going on!
Thanks for your time!!
