Stuart Boblett Posted March 23, 2021 Report Posted March 23, 2021 I need a part number or the PSI for the coolant cap on a 1982 with 305 engine. I have seen caps from 8 to 16 psi listed and am not sure who to believe.
IndyJimW Posted March 29, 2021 Report Posted March 29, 2021 AC Delco radiator cap for a 1982 305 engine is a RC27 16 lb cap. Good luck, Jim Wood
Gunslinger Posted March 29, 2021 Report Posted March 29, 2021 If the car has a closed coolant system make sure the cap is for a closed system.
