Advice Needed, Air Is Getting Into My Cooling System.when This Happens The Temp Starts To Rise And I Loose Heater Temp. It Takes Several Days Before This Will Happen. I Have Burped It Good And Have New Water Pump, Thermostat, Radiator, Cap.
So I Had The Head Gaskets Changed, Still The Problem Returned. So I Bought Combustion Gas Checker For Checking For Exhaust Gas In Radiator. The Radiator Showed Clean.
So How ????? Can Air Be Getting Into My Cooling System ????
Thank You
