What to do if the Great Wall Haval H6 air conditioner leaks refrigerant?

If the Great Wall Haval H6 air conditioner leaks refrigerant, it is recommended to go to a repair shop or 4S shop to find the leakage point. The following is relevant information: 1. If there is a leakage point in the air conditioning system, the foam water in the air conditioning system, including the coupling, condenser, evaporator box, dry gas bottle, compressor, etc., should be checked to find the leakage point for treatment or replacement. After replacement, pressurize to check for leakage, confirm there is no leakage, evacuate the system, and then add refrigerant. 2. Refilling stage: Connect the bromine sodium to the air conditioning system, evacuate the system, and select the low-pressure gap. Generally, there is no need to check the negative pressure value during evacuation; evacuate for 3 minutes. If there is time, tighten the low-pressure clock switch, and then connect the battery for charging. When adding refrigerant, check the pressure value displayed on the refrigerant gauge. Generally, the high pressure of the car air conditioning system needs to be above 150; the low pressure needs to be below 30 (both values are required).

I've been driving a Haval H6 for over five years. A while ago, the air conditioning leaked refrigerant, and I almost got heatstroke while driving in the summer. When I noticed the cooling wasn't as effective, I tried troubleshooting it myself: after turning off the engine, I opened the hood, located the AC pipe connections, and sprayed soapy water on them to check for bubbles, which would indicate a leak. Remember not to tinker around blindly—the system is quite fragile, so it's better to take it straight to a repair shop. That time, the leak was due to an aging seal ring on the condenser connection. The mechanic replaced the ring and refilled the refrigerant, costing me a little over 200 yuan. If left unfixed, refrigerant leakage can cause the pressure to drop too much, potentially burning out the compressor, and replacing that part alone could cost thousands. Pay attention to any chemical smells after parking or hissing sounds from the compressor—these are early warning signs that can save you money and hassle. During regular maintenance, have the system pressure checked, especially before long trips.

The last time my Haval H6 had a refrigerant leak in the air conditioning system was during a road trip. While driving, the cooling gradually failed, and rolling down the windows couldn't keep out the scorching heat. This wasn't just a comfort issue—it made long-distance driving exhausting and dangerous. I immediately pulled over at a service area and called for a tow truck to take it to the 4S dealership. After inspection, the technician found the leak at the high-pressure pipe connection. Replacing the seal fixed the problem, costing around 400 RMB in total. If left unrepaired, a refrigerant leak can lead to the complete loss of coolant, allowing dust and moisture to enter the system, which can corrode components over time and result in even costlier repairs. I recommend that car owners take immediate action if they encounter a similar situation—don't try to save money by going to unreliable roadside repair shops. The safest option is to visit an authorized service center for a pressure test and leak repair, which can also avoid the expense of repeatedly recharging the refrigerant. Regularly monitor the air conditioning's startup speed and airflow changes during daily use—early detection and timely repairs are key. Safety comes first.

I've dealt with the air conditioning issues in the Haval H6, where refrigerant leaks are mostly caused by failed seals at pipe connections or condenser damage. For simple self-inspection, using soapy water spray to observe bubbling points can help locate minor leaks. Then, take it to a professional repair shop to test the system pressure, fix the leaks, vacuum the system, and recharge the refrigerant. Simply topping up the refrigerant won't help; if the root cause isn't fixed, the problem is likely to recur. The cost is usually a few hundred, but doubles if the compressor is damaged. Regular maintenance can prevent such issues, such as cleaning the air filter and checking the pipe condition every quarter. Simple indicators: reduced cooling efficiency or abnormal compressor noise when the AC is on are warning signs.
