Ok, I know this may sound strange but here goes.
Night before last my son calls and tells me that the upper radiator hose is leaking on his 92 S10 Blazer 4.3L. No big deal, we go to the auto parts store, purchase a new upper hose, being sure to match it up with the old one.
Well this morning when he arrives at school the new hose is leaking! We just got in from looking at it and the alternator is CUTTING the hose!!
It seems that when the hose gets hot it is sagging and the alternator is hitting against it and cutting it.
Any suggestions?
