How to locate a Coolant Leak

1 - Use your eyes and a flashlight to see Coolant Leak.

Look underneath the vehicle and see where there is fluorescent green or fluorescent orange liquid dripping and then follow the flow back to its source. Remember it will follow the flow of gravity and will also wrap around objects.

2 - Find Coolant Leak by using pressure.

Special tools are available for around $80 dollars that allow you to simulate a hot engine without the risk of being burnt. These tools are like bicycle pumps that attach to the radiator in place of the radiator cap and allow you to pressurize the cooling system as it would when the engine is hot. These tools have a gauge on them and the pressure on the gauge should not exceed the pressure of the radiator cap. Once pressurized you can look around and see if the Coolant Liquid is coming out.

3 - Check your dipstick.

When you pull out your oil dipstick does the oil look milky? When water mixes with oil an emulsification effect happens making the oil more gooey and milky in color.

4 - Use your hands - Cold Engine

With a cold engine that is NOT running. Put on a disposable glove and feel in areas that you cannot see. Pull the hand out and see if you can see any fluid on it.

5 - Use your nose

Radiator Fluid (Coolant) has a very distinctive smell. If you smell this inside your car then you probably have a coolant leak in there.
