I checked the oil this morning. Just oil there. The radiator is full, after filling it up and driving 7 +/- miles back home up hill and down with the load still on the truck. Next question: The radiator cap doesn't seem to have the spring tension that the newer ones have and the overflow runs from the top of the radiator, not the fill neck. Does that mean that I have a non-pressurized cooling system? Just wondering if it boiled off?
