Radiator Drain Plug Leak
My son's 2001 325ci just started leaking coolant from around the blue radiator drain plug on the bottom of the radiator. The coolant is coming from around the black plastic fitting that the blue screw plug sits in. I looked up the part on RealOEM.com and found that the blue plug and the fitting can be removed and replaced as one unit. Have any of you fanatics had this problem before? Did a couple of searches and didn't find anyone who had done a thread on this. Any tips on changing this part out? Thanks!
