Car is over heating I changed radiator which was cracked then thermostat and it still overheating

Okay the water pump on this engine is driven by the timing chain. It is not very accessible. It is also not very likely to cause an overheating condition. Any air in the system will cause an air pocket and overheating. These engines can be difficult to bleed. Are you aware of the bleeder screw on the heater hose?

Make sure they know about the coolant bleeder on the heater hoses. This is how you get the air out.

Fill the radiator with the car off. Start the car and crack the bleed screw do not open it completely just enough so you see it drip slowly. Keep it open through the whole procedure. Next prop the gas pedal with a long pole. I use a long handle screw driver about 3 feet long. Run the car at about 1500 rpm. Look for air bubbles. You should have the heat on too and keep checking to see if it gets hot. This procedure is different then in the book but I have found it works well. Any air in the system will cause it to over heat eventualy.
