I've got a 6.2 radiator in my '85 K10. The stock hose is 4 inches too short and has a 1.5" end. The radiator has a 1.75" opening. Back in the day they used to sell hoses that weren't pre bent but were ribbed so you could bend it to fit. NAPA doesn't carry them anymore. Anyone know where I can find one?
I believe Dayco makes some flexy radiator hoses and Advance Auto Parts should have a few on the rack.
I've bought that type of hose at my local carquest. but another option is to use a piece of exhaust tubing to lengthen the hose.. ==2cents
