My suggestion. Let car cool off till cold. Remove rad cap and remove bleed screw. Fill with water until fluid starts to run out bleed hole. Solid fluid this means no more air bubbles. Start car and rev lightly to remove additional air bubbles. add fluid as needed until only fluid comes out air bleed. Cap air bleed and rev a few time more and add any fluid to top off side tank and then put on rad cap. Drive car until it just starts to overheat (If it does now). Time it so you can pull in your driveway before the temp gauge is over 3/4's. Look for leaks under car. If no leaks let it cool and remove cap. remove bleeder and run car and see if there are more air bubbles in system of loss of coolant. If there are major air bubbles your head gasket is gone and allowing exhaust gas in the cooling system.
Also follow what Steven is stating about look for coolant flow. Without coolant flow it will always overheat. |
