The engine may be worn out and too difficult to ever get tuned. It suggests that vacuum might be inadequate, that vacuum advance does not work, and that engine has too much ignition advance at highway speed, causing overheating and even possible detonation. But you usually don't need or benefit from a fan at highway speed. hydraulic clutch on fan is usually worn out. Blocked jacket flow will cause local hot spots and risk a blown engine.Ģ. Heavy rust/mineral deposits block heat transfer and may require removal of all core plugs with mechanical cleanout or even entire block soaking.

There should be at least a 20 degree difference if not it is time to check the radiator. You might also want to get an infrared gun and check the temperature of the water coming out of the thermostat housing into the radiator and check the temperature coming out of the radiator into the water pump. You could take out the radiator and have it taken apart and have the tubes brushed cleaned. Royal Purple makes a product called Purple Ice which breaks down the viscosity of the water and helps to keep the water temperature down. Flush the system completely again and add coolant. If there is scale in the system you will see it in the water you just drained. Shut the engine off and let it sit for a few hours then drain the system again. Go to a Hardware Store and buy a gallon of Muriatic Acid pour it in the cooling system and had water to bring it up to the operating level and start the engine and let come up to temperature. If the cooling system is clogged or there is scale in there, drain the complete system including the heater core.
