1996 BMW 328I Overheating PLEASE HELP!!!
Ok so I bought the car in may and a week later the radiator blew, I replaced it with an all aluminum one, but ever since then the car would start to overheat if at idle too long, but fine when driving. yesterday I was washing the car and I forgot about the idle problem and left it on for about 30 minutes so I could listen to the radio without draining the battery, when I went to take the keys out I noticed it was all the way at red! I shut the car off, and waited about 15 minutes, then took the cap off the radiator, all the coolant came gushing out, so I waited a few hours, refilled with water, and then drove about 2 miles to advanced auto to get coolant it made it there fine with the temp gauge at normal but when I got out the water was steaming out of the cap, I waited about an hour put the coolant in, and went to drive home, after that it started overheating while driving within 30 seconds! I had to pull over 5 times and let it cool down to get home, can anyone tell me what they think the problem is? I have just bought new water pump with metal impeller, thermostat, aluminum thermostat housing, and radiator fan clutch as preventative measures and they should be here this week, Im just hoping I dont have a blown head gasket! Thanks in advance, Mark
