Cylinder head gasket
Symptoms | Reason and features |
A.The coolant level keeps dropping | A small amount of coolant enters the combustion chambers. This can happen without visible signs of malfunction for a long time |
B. Significant loss of coolant. The car emits white smoke from the exhaust pipe when the engine is warm | When the engine is warm, the coolant enters the combustion chamber in a significant amount, evaporates there and is emitted in the form of white fumes |
IN. Air bubbles rise from an open expansion tank or a large amount of coolant flows out when the cap is open | Combustion products enter the cooling system. Exhaust gas smells from the filler neck |
G.Iridescent colors or black film on the surface of the coolant | Oil from the lubrication system enters the cooling system |
D. Gray or brown emulsion on the oil dipstick pulled out or the oil is saturated with water droplets | Coolant has entered the lubrication system. Caution: Water entering the engine oil can damage the bearing. Don't start the engine again! Have your car towed for repairs. Replace cylinder head gasket |
