==> Bypassing Aux Radiator Fan?
 

Hey guys. I almost have my bimmer's overheating problem taken care of. It seems to help when I have the aux radiator fan blowing at all times. What can I hook it up to so that it runs whenever I turn the car on? Also, is it normal for when the car starts to overheat that coolant bubbles out from under the radiator reservoir cap? I didn't remember that happening before I had these issues. I took the cap out and the o ring in it and everything else seems intact. I just wanted to ask before I spend $25 on the stupid cap. THANK YOU!!!

i think your overheating issue may lie at another problem. have you changed your thermostat lately, fan clutch, did you do a proper flushing if you changed the coolant, i mean proper bleeding (get those bubbles out) when was the last time you replaced your water pump?

i don't hink you want your car overheating often and for a long periods of time, the engine is too fragile for that.


just my 2 cents. :thumbup
