How to clean the air inlet of automobile air conditioner

1. First remove the fuel injector, intake manifold and some accessories around the engine, especially the throttle. The throttle valve is installed at the intake manifold, and cleaning the throttle valve is one of them, so before removing the intake manifold, remove the throttle valve and place it properly.

2. Secondly, it is necessary to remove the ignition coil and spark plug, mainly to pump the cleaning agent directly into the combustion chamber of each cylinder.

3. Next, the cleaning agent will be pumped in from the air inlet and the spark plug device. Unlike previous cleaning agents, this cleaning agent is foam-like. The advantage of this form is that it can fully soak the carbon deposits attached to the cylinder and air intake. The cleaning agent has strong dissolving ability to carbon deposit. After soaking for a period of time, although the carbon deposit will not fall off by itself, the hard carbon deposit at low temperature can be easily removed with a small brush. Finally, with the use of cleaning agent, carbon deposits can be removed from the air outlet.

4. Finally, the cleaning liquid accumulated in each cylinder is pumped out by a vacuum tank, and the engine is restored to its original state through the reverse process of disassembly. Then, when the engine is hit, the exhaust pipe will emit choking white exhaust gas. After the exhaust color returns to normal, it takes about two hours to finish the cleaning construction.
