Hello. I have a 1970 challenger 383 auto, with 2998960 22" radiator. 16 lbs rad cap. When I drive the car it runs great not even close to overheating. But when I turn the car off it heats up obviously and spill out of the radiator neck nipple. Do I need a coolant recovery system like the 73 74 challenger had? If so I'll get one, and whats the correct radiator cap to use with the 73 74 recovery system? I heard they need to be a two way cap...
Thanks, any help would be great
