Sounds like the engine is heat soaking. First thing to do is flush out the cooling system and add fresh coolant. Since you've been having issues I'd suggest using a chemical cleaner while flushing the system. BUT on an older model this will most likely cause something (radiator, water pump, etc.) to spring a leak! If the cooling system flush/cleaning doesn't solve the problem you could have a worn timing chain. This is especially suspect if you've got some miles on the car, say 150,000 or higher. A worn timing chain will cause the valve timing to become retarded (late) and cause loss of power, heat soaking, boiling over, and possibly late transmission shifting. HTH. -Jim

When you stop do you see a puddle of coolant under car? Where? The coolant has to be going somewhere. These cars have timing belt driven water pump and when the pump wears out it will leak coolant in by the timing belt and out the weep holes on the bottom of the timing belt cover.
