How do you test for combustion gases in a cooling system?
Squeeze and release the squeeze bulb on the suction tube repeatedly to draw air from the coolant system through the fluid in the suction tube. The fluid in the tube is normally blue, but if exhaust gases are present in the coolant, the fluid will change color from blue to yellow.
How is combustion leak test conducted?
Test the tool and fluid by exhaling into a cupped hand and sucking the exhaled air through the intake hole into the two chambers by squeezing the rubber bulb two or three times, holding the Leak Tester in a vertical position. (CAUTION: Do not put the rubber intake end in your mouth).
How do you tell if your coolant is contaminated?
Symptoms of bad coolant
- Your coolant is dark, murky, smelly or full of debris. If your coolant looks (or smells) bad, it’s way past its useful life.
- Your temperature gauge reads higher than normal.
- Your engine overheats.
How is a combustion gas test done in a radiator?
Force radiator gases through test fluid by squeezing bulb. Continue to force radiator gases through test fluid by squeezing bulb for about 1 minute. If fluid turns YELLOW (in diesel engines, fluid maybe turn green-yellow), a combustion leak is present. If fluid remains BLUE, a combustion leak is not occurring while test is in process.
How do you test for exhaust gases in coolant?
Pour the leak fluid into the suction tube, both contained in the combustion leak test kit. Insert the suction tube into the radiator filler neck manually.
How do you test for a leak in a radiator?

How does a pressure test work on a radiator?
The pressure test can help you locate or confirm hard to find leaks. The test uses low pressure to force coolant to come through the exterior leaking spot, or prove that the system can’t hold pressure if you’re dealing with an internal leak or a damaged radiator neck.
