1952 1/2 ton Chevy, 1954 235 engine. Here's the problem: truck will overheat after a few hours on the road due to lack of coolant. I know this because I'll stop, open up the radiator and add about a gallon every day or so. But there are absolutely no signs of coolant leaking- checked hoses, heater, drain cocks, everything. This leads me to conclude that coolant is somehow leaking inside the engine/head. The oil is not showing any signs of water, however. Has anyone ever heard of/ seen this, and if it's true, is there anything I can do to fix it short of pulling the head? Thanks brothers,
Tyler
