55 Caribbean Over Heating

Posted by JCH On 2020/8/6 17:40:26
Recently acquired a '55 Caribbean. The car has overheated and vapor locked since day one. I have helped the vapor lock issue by insulating the gas lines and adding an electric gas pump back at the tank. The engine over heating continues. I had the radiator serviced, used a cooling system flush, changed the thermostat and cap. I removed the water pump and water distribution manifold to view the condition of the water ports. The ports were in good condition. The water pump looked ok, no leaking. Considered installing a flex fan, but only have 1 3/4" clearance from fan hub to the radiator. I would appreciate any new ideas before pulling the heads to check for blocked water passages. Thanks, JC
