What is the name of the test that uses colored liquid to find exhaust gas in cooling system?
The leak detector works by drawing vapour from the cooling system through a specialist test indicator fluid; this fluid is bright blue in colour, but in the presence of carbon dioxide (CO2) it turns yellow.
What is the name of the test that compares the density of water and coolant?
A hydrometer is an instrument used for measuring the relative density of liquids based on the concept of buoyancy.
Why does my coolant smell like exhaust?
If you’re absolutely sure that you smell coolant out of your exhaust pipe, then that means it’s leaking into one or more combustion chambers, getting burned up and emitted out of the exhaust.
How accurate are antifreeze testers?
Laser Ethylene Glycol Antifreeze Tester 4293 review We also found the results were similar, with poor accuracy for 33% concentration anti-freeze and readings around nine degrees off, but better results for 50% concentration.
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.
What’s the normal reading for a coolant test?
All these are functions of coolant EXCEPT… A normal reading when testing coolant for galvanic activity is ____. As the percentage of antifreeze in the coolant increases,… A normal reading when testing for electrolysis in the coolant is ____.
How much chlorine can you test with color wheel test?
The test kit can be used to measure free chlorine and/or total chlorine (using different chemicals in the kit), with a range of 0 – 3.5 mg/L, equivalent to 0 – 3.5 ppm (parts per million). Benefits of the color-wheel test kits: Accurate readings if used properly
What should the reading be for electrolysis in the coolant?
A normal reading when testing for electrolysis in the coolant is ____. Technician A says that the radiator should always be inspected for leaks and proper flow before installing a rebuilt engine. Technician B says that overheating during slow city driving can be caused by a defective electric cooling fan. Who is right?
