Hi Clifford

I would suggest air in your cooling system.

This may be due to coolant being drained i.e antifreeze renewal by previous owner.

One way to check this (Make Sure Engine is Cold), take off one end of the highest water pipe on your engine and manually fill it with water and try to refit without losing too much of the water you've just added. You should also have a bleed screw on the top of the engine.

Best of luck
