420sel coolant leak
I have a 420SEL with a serious coolant leak, which is coming from the overflow on top of the radiator. I've checked the hose and even though I can't see it I'm sure there is a crack in the little nipple that the hose fits on. My question is what can be done about this short of replacing the whole radiator? The radiator is almost new and has no other problems and I can't see spending that kind of $ just to get a new plastic nipple. (I still can't believe a car of this caliber would have something so shoddy on it. )
Thanks in advance!
