Got a problem resolved on my #Chevy #Squarebody #Truck yesterday. Ever since the radiator was changed in 2018, one of the heater core hoses would leak about two litres of anti-freeze during the cold winter days, due to expansion. Thought the problem would have been fixed last fall when a fitting was changed, but the whole hose needed to be replaced to properly remedy the issue. Got that done with both hoses swapped out (to be on the safe side) as the other non-leaking one had stiffened with age.
