I recently had some upgrades done on my ram 2500. Head gasket and revalving, studs for head, new exhaust manifold, new turbo with waste gate, 5" exhaust, egr delete, tuned. My problem is it seems to be building pressure in the radiator but the thermostat doesn't seem to be opening. The thermostat was replaced with an OEM with same result. A lower temp thermostat was installed with same result. Although now it does not overheat. When I release the pressure on the radiator cap alot of air bubbles up into the reservoir and also raises the volume so it drains out of the reservoir. The radiator then needs fluid and I fill it only to have the same thing happen. I'm to the point of running with a thermostat. Help!
