OVERHEATING - blowing out coolant

Does the coolant overflow the tank while the car is running or when you shut it down? The blown head gasket syndrome rears its ugly head typically after you shut the engine down. Other things to check would be the thermostat by taking it out and boiling it in water to see if it opens. Make sure when it's installed that the spring portion is going into the block housing and not the other way around. Did you have problems before the rebuild? Make sure your radiator is not rotted or clogged internally or externally. Check for leaves and debris between the radiator front and the air conditioner condenser rear blocking airflow. Take the radiator And look inside to me if cores are blocked by corrosion. One way to check for flow is to put a garden hose going into the top and see that it flows freely. Rinse with distilled water. You might want to check under the oil filler cap to see if there's any gray sludge from coolant getting into the oiling system. Head bolts should be torqued to 72 foot pounds for standard bolts or 90 for ARP studs with nuts and the ARP grease. Fan clutch working normally? If have a blown head gasket you need to talk to whoever worked on your engine. Using a stacked metal head gasket requires precision surface treatment. Are you blowing oil out of any of the seals? That would indicate compression a leak into the Oil system.
