Product Overview

This easy-to-use test kit uses color-changing CO2 test fluid to identify combustion gas presence in your vehicle's cooling system, eliminating guesswork when diagnosing head gasket failures, cracked cylinder heads or engine block damage. The unique dual chamber design prevents test fluid contamination for more reliable results and longer test fluid life.

Common Faults & Replacement Symptoms

  • White sweet-smelling exhaust smoke indicating coolant burning in combustion chambers
  • Coolant loss without visible external leaks, or bubbling in the radiator/coolant reservoir
  • Engine overheating with no obvious cause, or milky oil appearance on dipstick
  • Persistent misfiring on one or more cylinders with no ignition or fuel system faults
  • Failed emissions test due to high hydrocarbon levels from coolant entering combustion chambers

Ideal For

This kit is ideal for DIY vehicle owners, professional automotive technicians, heavy equipment mechanics and motorcycle repair shops looking for a reliable, affordable tool to diagnose head gasket and cooling system issues across a wide range of vehicle types.

Can I use this kit for my motorcycle?

Yes, this test kit is compatible for all gasoline and diesel motorcycles with 17-45mm radiator or coolant reservoir ports, making it suitable for both street and off-road motorcycle diagnostics.

How many tests can I perform with the included test fluid?

The 8.5oz test fluid is sufficient for approximately 15-20 full tests, depending on how much fluid is used per test and how well you maintain the tester chambers between uses.

Is this test kit compatible with heavy equipment like excavators?

Yes, this kit works for all heavy equipment including excavators, road tractors and forklifts with gasoline or diesel engines, as long as the radiator or coolant reservoir port size is between 17mm and 45mm.

Do I need any additional tools to use this kit?

No additional tools are required for basic handheld testing, though a separate brass adapter (not included) can be purchased for a more stable, permanent connection to the cooling system.
