Peter;
        Is there a big air bubble in the reservoir that will not bleed
out? If so you may have combustion gasses being forced into  the coolant
jacket. This causes a bubble inside the engine exposing the top of the
cylinders , hence the running hot. You can buy a kit to test for gasses,
take it to a friendly mechanic with an emission testing machine to
"sniff" the overflow tank or affix a balloon over the vent of the
overflow tank. If it inflates.....bad news.
Drive Safely & Good Luck
