First pressure test the cooling system and the cap too and see where it is going.

Overheating can be caused by anything that decreases the cooling system’s ability to absorb, transport and dissipate heat, such as a low coolant level, loss of coolant (through internal or external leaks), poor heat conductivity inside the engine.

The coolant also has to get rid of the heat it soaks up while passing through the block and head(s). So the radiator must be capable of doing its job, which requires the help of an efficient cooling fan at slow speeds.

Good advice and I agree.
