What are the symptoms of bad oil cooler?

Some of the common symptoms of oil cooler gasket failure include:

Oil Leak. When the oil cooler gasket fails, it is unable to keep oil in.
Overheating Engine.
Contaminated Oil.
Decreased Engine Performance.
Black Smoke.
Vibrations.
Expanded Radiator.
Engine Temperature Changes.

What causes oil to get into the radiator?

If it was this way, you’d expect to see some oil get into the radiator as the expansion/contraction of the radiator fluid inside the cooling system is going on during normal operation. It probably wouldn’t draw much in, just enough to make a mess.

What causes a radiator fan to go out?

Radiator fans will burn out a fuse because it is failing and creating too much amperage. When the electric motor surges, the fuses blow to ensure the system stays safe from this extra power. You can change the fuse, but a defective fan will probably cause another one to go out. 3. Vehicle Overheating

Why do I have water in my radiator?

There are only few obvious where this can happen: One is at the head gasket where oil can leak across the top of the head to the water passages (or into the cylinder or out the edge of the gasket) if the head isn’t properly torqued of perhaps if there is corrosion in the cooling system. Or the gasket could just be failing.

What does bluedevil radiator flush and oil degreaser do?

BlueDevil Radiator Flush and Oil Degreaser is a 3-in-1 cooling system cleaner that will flush your radiator, degrease the system and removes any rust build-up to restore your cooling system to its full potential.

Where does the coolant go in a surge tank?

As the engine increases in operating temperature, coolant will expand in volume, taking up more space inside the radiator, coolant system hoses, and motor. Since we fill our radiators when the engine is cold, the overflow of fluid is collected inside the surge tank. The surge tank hose carries the overflow from the radiator to the storage device.

Why is there oil on top of my radiator?

Since oil is lighter than water most of the oil in your cooling system will float to the top of your radiator or coolant overflow tank. If you see an oil slick floating on your coolant it’s important to clean out your cooling system to make sure your engine doesn’t overheat.

What causes hot radiator fluid to leak from surge tank?

Because of this fact, the surge tank hose can come into contact with warm or even hot engine parts. If this happens too often, a hole can develop causing hot radiator fluid to leak. When it hits the ground, it will typically be on the right hand side of the car.

What causes the surge in a car engine?

Proper engine performance is dependent on a very precise balance of air/fuel mixture, spark timing and exhaust management; any deviation from any of these parameters will cause malfunction, which is often expressed as “surge” (rapid acceleration/deceleration cycles).
