How to block the hot water pipe of automobile air conditioner

1. First untie the buckle of the sewer pipe with carp pliers, then unscrew the water inlet pipe and pull it out. You need to insert the nozzle of the high-pressure air pump into the water inlet pipe of the warm air tank and turn on the high-pressure air pump, so that high-pressure air will enter the water tank and the dirty things in the water tank can be blown out.

2. Secondly, add the prepared cleaning agent to the water tank, then add tap water to the water tank that needs to be filled, then let the vehicle idle for 30 minutes and turn on the warm air of the air conditioner.

3. Before changing water, it is necessary to use high-pressure gas to make the pipeline unblocked. Need to add water three times and circulate many times. When the water from the pipeline is clear and bright, it means that the water tank has been cleaned. You can add antifreeze to the water tank at this time.
