This method allows for the detection of exhaust gases entering the cooling system, identifying a cylinder head gasket failure or cracks in the cylinder head without engine disassembly.
The $CO_2$ test reacts to the presence of fuel combustion products in the antifreeze resulting from a loss of airtightness between the combustion chamber and the cooling system.
The method is safe for the engine and takes a minimal amount of time.
ЩоWhat the CO2 test shows
• Cylinder head gasket failure
• Microcracks in the cylinder head and the block itself
When inspection is required:
• Engine is overheating
• Constant loss of coolant without external leaks
• Bubbles in the expansion tank
• Hoses become hard after starting the engine
• White smoke from the exhaust pipe
• Emulsion formation under the oil cap
Advantages of CO2 diagnostics:
• Does not require engine disassembly
• Fast results
• High accuracy
• Helps avoid costly repairs
• Suitable for both gasoline and diesel engines
