Well, honey, bleeding the air from a cooling system is as easy as pie. Just locate the bleeder valve on the radiator or near the thermostat housing, open it up, and let all that pesky air escape until you see a steady stream of coolant. Make sure your engine is cool before you start messing around, unless you want to end up looking like a hot mess. And remember, safety first, because nobody wants to deal with a burnt hand or a blown gasket.

The most likely problem is a malfunctioning engine thermostat. Sometimes they just stop working and lock in place anywhere from full-open to fully-closed. You could also have crud in the radiator; this can be at least partially helped by using a radiator flush kit. Lastly, check your radiator hoses for kinks and blockages. Good luck. air pockets in cooling system,Use the bleeder screw at thermostat to release air.
If there are no bleeder valves, simply remove the radiator cap, fill the radiator to the top, start the engine. With the engine running keep the coolant level full and watch for air bubbles. After the engine has reached full operating temp and you no longer see any air bubbles escaping shut it off and replace the cap. If there are bleeder valves use them to remove trapped air after the engine is running. Be careful as not to get burned by hot coolant.
