Hi friends,
My '86 6.9 f250 with 79k original miles has been resting this winter and not started in 3 months (batteries are charged). Before putting her away for winter, I filled the coolant reservoir to the proper level. The reservoir is now empty and there's pressure in the system (top hose is rock hard and 13lb Motorcraft rad cap leaks if opened). I've noticed before that days after driving the coolant system retains pressure. There are a couple drips under the right side of the radiator (haven't diagnosed that yet).
Why would I have pressure in the coolant system? Is this normal?
