Why is my radiator fluid milky?
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 when car coolant is a milky color?
by Rob Wagner. A milky color in an automobile’s coolant could be the sign the engine has blown a head gasket, and may lead to catastrophic failure of the engine.
What causes sludge to build up in the radiator?
Radiators are made of metal. Over time, antifreeze degrades. As it loses its protective qualities, PH levels change and corrosion sets in. Once this begins, rust, sludge and scale build up through the entire cooling system, including the engine. The sludge can block the flow of coolant, causing the engine to overheat and leak.
Where are the coolants located in a car?
Most motor vehicles have coolants that feature a bright lime, green or orange color. Newer models have a plastic reservoir in the engine compartment either at the front of the engine near the radiator or against the firewall. Without removing the cap, a vehicle owner can simply look at the reservoir to observe its level and color.
What causes brown slime / sludge in Beyer motor?
According to complaints received by Consumer Affairs, Dex-Cool reacts with the plastic sealing surfaces, causing the intake manifold to leak. The residue left behind by the breakdown is very sticky and thick like mud. Only a chemical flush will remove the sludge.

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.
What causes coolant to bubble in the radiator?
When your engine is running, the high pressures in your combustion chamber can push exhaust gases into the cooling passages causing coolant to bubble in the radiator and pressures to get so high that coolant will actually be forced out of the coolant reservoir.
What kind of coolant does a radiator use?
You’re no doubt familiar with the conventional “green” coolants found at most retailers due to their low price. The additives in these coolants use inorganic-acid technology (IAT), which relies exclusively on inorganic salts such as nitrites, phosphates and silicates for protection.
