COMBUSTION GAS LEAK TEST K - Mastercool

The Mastercool 43707 Combustion Gas Leak Test Kit is an essential diagnostic tool for professional automotive and industrial technicians, engineered to accurately identify internal engine leaks. This kit provides a reliable method to visually detect combustion gases within the cooling system, enabling mechanics to confirm critical issues such as head gasket failures, cracked cylinder heads, or engine block leaks before extensive disassembly. It serves as an indispensable asset for efficient and precise preliminary engine fault diagnosis in a professional shop environment.

Key Features

• Accurate Combustion Gas Detection: Precisely identifies CO2 from combustion gases in the cooling system, directly confirming internal engine leaks, including head gasket and casting failures.
• Dual-Chamber Filtration: Features an advanced dual-chamber design that effectively filters out alkaline particles, significantly reducing the risk of false positives and enhancing diagnostic confidence.
• Broad Vehicle Compatibility: Suitable for use on most passenger cars, light trucks, and a variety of diesel applications, requiring access to the radiator or surge tank.
• Clear Visual Results: The test fluid changes from blue to yellow for gasoline engines and blue to green for diesel engines, offering an unmistakable, at-a-glance diagnostic result.
• Durable, Shop-Ready Construction: The rugged test chamber, rubber bulb pump, and test fluid are housed in a durable plastic storage case, ensuring protection and easy transport between service bays.

Applications

Utilize the Mastercool 43707 kit to verify suspected internal combustion leaks when diagnosing symptoms such as:

• Persistent engine overheating or unexplained pressure buildup in the cooling system.
• Unexplained coolant loss without visible external leaks.
• The presence of white exhaust smoke or visible coolant contamination.
• Bubbles observed in the radiator or coolant expansion tank.
• Engine performance issues including loss of power, rough running, or misfires potentially linked to head gasket failure.
