CO2 TEST FOR THE PRESENCE OF COMBUSTED GASES

We present to your attention the Carbon Monoxide (CO) or Exhaust Gas Presence Test in the cooling system. With the help of this CO test, you can quickly and easily determine the airtightness of the cooling system.

Very often, the engine loses coolant, and there are no signs of external leaks. In such cases, perform a CO test. It is highly likely that coolant is entering the car’s cylinders, causing a drop in the coolant level.

Signs of a damaged Head Gasket, Cracked Cylinder Head, or a Cracked Block include:

– A decrease in the coolant level, necessitating frequent refills (because it is entering the cylinders and being expelled through the exhaust).

– A sudden and rapid increase in engine temperature at times (due to hot gases entering the cooling system, heating the coolant quickly).

– Hardening of the radiator hoses (because the pressure in the cylinders is much higher, and gases are pumped into the system, stiffening the hoses).

– When starting the car in the morning, the engine may stall and run unevenly (because the coolant in the cylinders is non-combustible, fouling the spark plugs, hindering the ignition, and cylinder operation).

– Coolant leakage from the car’s exhaust (the gasket is severely damaged, and a large amount of coolant passes from the cooling system into the cylinders and is expelled through the exhaust).

– Air bubbles in the coolant expansion tank on a cold engine (the gasket or cylinder head is severely damaged, and gases from the cylinders enter the cooling system in the form of bubbles).

– The heater, when the engine is warm, starts blowing cold air (because gases are in the cooling system, and as the heater core is the highest point, it stops transferring heat to the car’s cabin).
