My eldorado was overheating and I took it into the shop and was informed it needed a new water pump. I choose to repair this myself and save a little money. After replacing the water pump and thermostat the car is still overheating. I have checked for leaks and it appears there are none. What should I look for next?

Check for blown head gasket - have CO coolant test done.
