Started truck and drove 4 miles for a total of about 20 minutes. Noticed top radiator hose had a lot of pressure and the newly replaced radiator cap was functioning to allow the overflow into reservoir. The radiator was very hot as well as the new thermostat and housing. I let engine cool for few hours in garage. Pressure on top hose was gone and expansion tank was now near empty (functioning as it should).
The lower radiator hose feels like there is no coolant in it when squeezed, nor is there any fluid in the heater hoses that flow into my Vintage Air system.
Unfortunately, I believe the cooling system is blocked somewhere. The radiator is new as well as the water pump, thermostat and housing (top and bottom).
The engine was rebuilt and has less than 50 miles on it but it sat for past 7 months. Could there be rust, gunk and scaling in the engine causing blockage? If so, what is the best approach to remedy?
