That's normal...there is usually residual heat. Turn the AC on for a
mement and that will extract heat quickly.

No cap...not possible. There should be one on the expansion tank that
connects to the radiator. Is the expansion tank filled to the proper
level?

Shizzle???

You may have an air bubble in the cooling system. Did you bleed the
cooling system when the fluid was drained out?

If your car has a viscous damped fan that may not be operating
properly, or the belt may be loose. If you car has electric fans then
one may not be working properly.
