3. Oil in the cooling system.
4. Coolant in the oil.

What happens if Coolant mixed with oil?

It is quite a bad occurrence when the two mix and usually means that the gasket has failed to function as required, creating an internal leakage which could easily damage the engine. Some of the reasons why engine oil mixes with the coolant are: A broken/damaged head gasket.

How do you test an oil cooler?

Connect a 1 inch hose to the other oil cooler nozzle and, using adapters, connect and air supply to the 1 inch hose. Submerge the oil cooler in a tank of water. Pressurize the oil cooler, using the compressed air supply, to approximately 0.8 bar (12 psi). Look for evidence of air bubbles coming from the oil cooler.

What causes an oil cooler to leak?

Most oil leaks stem from bad connections or cracked oil pans, engine gaskets or seals. Another place to look is the oil cooler adapter, which connects oil lines and is itself sealed with a gasket. When the problem is a bad oil cooler, oil will puddle on the ground.

Coolant leak is a serious problem relating to high oil level.
