I have an unusual problem with my M923A1 that i'm hoping someone can offer some insight on. The coolant system is creating pressure when COLD. While running, I am not losing a drop of coolant. When I park the truck and let it sit overnight, there is a small puddle of coolant underneath the truck. There is so much pressure building up in the system when cold (not running) that coolant is actually being forced out of several coolant hoses and even seeps out of the ends of the radiator slightly. I've replaced the cap, but it baffles me how I could be getting pressure while cold and not cause any issues while hot ?? In the meantime, I've been leaving the cap loose while parked - but that, of course, is just a band aid. Any ideas would be greatly appreciated !
