Radiator puking

Generally, Mopars use a 13 pound cap. I like using the lowest pressure cap I can get by with. It puts less stress on the cooling system. A lot of times this happens, the radiator has been overfilled. You're not supposed to fill the radiator slam to the top. There needs to be between 1-2" from the top of the fill neck for expansion.

Yes and yes.

Crusty stock radiator, 13 lb cap, no overheating and no puking @100 degree temps. Hard to see the level but it’s about 1 knuckle down if using your finger.
