hello i am new to the forum, but need help with overheating. i have a 429 and large alum 3 core radiator with elec fan, but even for a short drive the coolent is venting from the stationary cap and runs 220 and above? i would fill the coolent but never fails.. its 40 degrees and if im out for 30 min coolent will be covering the engine compartment. nothing is broken or leaking (dry once parked). thanks in advance
