Hi rs2600,
Sorry it took so long for a reply, I don't think too many members that help with auto issues peek in this sub-forum very often. They hang out in:

The first thing to check is the coolant level in the radiator.... but not when the engine is at operating temperature. Check the coolant before starting the car.
If the coolant is OK, it might be the thermostat needs replaced.
