How to Use Automotive Air Conditioning Leak Sealer?

[Oliver]

Usage method of automotive air conditioning leak sealer: 1. Turn on the air conditioning cooling system to maximum, open the cap and ensure the air conditioning compressor is running. If the air conditioning lacks refrigerant, replenish refrigerant until the clutch engages and starts operating, and the compressor runs; 2. Shake the bottle to mix the refrigerant with the leak sealer. Start the engine and turn on the air conditioning cooling system to maximum. Hold the bottle upside down at the low-pressure filling port, turn the valve clockwise, and gently shake until the bottle is empty. Disconnect the filler, remove the bottle from the hose, and turn the manual valve counterclockwise until the perforation rod is in the upper position. After filling with the necessary amount of refrigerant, run the air conditioning system for 15 minutes to allow the leak sealer and refrigerant to circulate thoroughly.

As someone who enjoys tinkering with cars, I've found leak sealants quite practical on several occasions. First, you need to confirm that the AC system truly has a leak - usually insufficient cooling or unusual noises indicate leakage. Park the car and turn off the engine, wearing gloves to protect your hands. Locate the low-pressure port connector in the engine bay - be careful not to mistake it for the high-pressure port as that's dangerous. Before using the sealant product, read the instructions carefully as some require special tools for injection; add it slowly without rushing. After adding, start the engine and run the AC at maximum fan speed for about 10 minutes to circulate it. Check the results - if cooling is restored, it's successful. However, note this is only a temporary solution for minor leaks. If the effect isn't lasting or the system makes strange noises, stop using it immediately and get professional repair to avoid compressor damage. Regular AC maintenance is more reliable for preventing such issues.

As an ordinary car owner, when I first tried using a leak sealant, I found the steps not too difficult but requiring a bit more patience. First, park the car in a well-ventilated area, turn off the engine to ensure safety. Locate the low-pressure port of the air conditioning system, usually marked with an 'L'—don't confuse it. Read the product packaging instructions to determine the appropriate amount to add to the port, preferably using auxiliary tools to prevent gas leakage. After completing the injection, start the car, turn on the air conditioning, and let it run for 8-10 minutes to circulate the coolant and check if the leak is fixed. Check if the cooling inside the car has improved; if not, don't force it—retry to avoid clogging the system and causing other faults. My experience is that such products work well for small cracks but shouldn't be relied on long-term; professional repairs are more thorough. During maintenance, checking the filters and pipes is also important to prevent issues.

After studying automotive air conditioning principles, I found that leak sealant uses sealing colloids to fill leaks, which is convenient to operate but requires careful execution. After parking the vehicle, locate the system's low-pressure valve, connect the leak sealant injection device, and slowly push it in to ensure sealing. Run the air conditioning for 10 minutes to allow the liquid to flow and cover the leak point, then check the cooling effect. It can temporarily address minor leaks, but for larger holes or complex systems, it may fail or even affect the condenser. It is recommended to regularly use pressure testing to diagnose the root cause and reduce reliance on such products. Choosing a reputable brand with fluorescent dye can aid in subsequent detection and more effectively maintain system longevity.
