Why does my coolant look GREY?

Why does my coolant look GREY?

A strange dark or gray, milky color in your coolant, or white antifreeze, is caused by a significant problem with your head gasket. When you notice milky oil in the car, it’s because the coolant has leaked into the combustion chambers and mixed with the motor oil, so the color is from the diluted oil.

What does it mean if your transmission fluid is gummy?

An oily sheen, or oil droplets seen in the radiator or coolant recovery reservoir can indicate a ruptured transmission cooler tank. The underside of the radiator cap may exhibit a gummy residue as well. Automatic transmissions often succumb to seemingly slight deficiencies in fluid quality or quantity.

What happens if engine coolant mixes with transmission fluid?

Engine coolant surrounds the tank to help keep the fluid inside at a constant temperature. Any rupture of the internal radiator tank can allow coolant to mix with, and contaminate transmission fluid. The engine coolant can also become polluted by the transmission fluid,…

Why is there sludge / slime in my radiator?

Mixing of incompatible coolants can cause the additives to “drop out” of the solution and form radiator sludge or slime. Contaminated coolant: A bad head gasket or cracked cylinder head can allow oil and coolant to mix, resulting in sludge. In vehicles with automatic transmissions, the engine-cooling system also cools the transmission.

How does transmission oil get into the radiator?

Small droplets of transmission oil separate and rise to the surface of the coolant in the radiator. This inspection often involves the removal of the radiator cap, and this action should never be attempted until the radiator cools completely.

What happens when radiator coolant leaks into transmission?

The Strawberry Milkshake of Death Ruptured radiator cooler tanks are forcing coolant into the five-speed automatic transmission through the cooler lines. Not only does the radiator stop cooling the transmission, but the resulting slurry of coolant and transmission fluid eats valves, erodes seals and speeds up corrosion.
