Note: If the ports are not labelled, try connecting the recharge kit to both unlabeled ports on the AC hoses. Remove the cap from the low pressure service port labelled L, and connect the AC recharge kit.Turn on the AC and set it to the coldest setting, and the fan speed to maximum.This information is typically located under the hood and/or in the owners manual. Check which type of refrigerant your vehicle uses.Open the hood of your Town and Country.You can recharge your AC through the low-pressure port with a do it yourself AC recharge kit. One is labelled H for high-pressure and the other one is labelled L for low-pressure. There are two ports in the air conditioning system of Town and Country. How to recharge AC refrigerant the easy way If your vehicle has been in an accident, you should inspect the condenser and its hoses for leaks. ![]() Since the condenser sits at the front of the vehicle, it can get damaged even in minor accidents like running over a tree branch in a storm. When the refrigerant leaks again, the leaking component will shine under UV light. The leak can be diagnosed by injecting small amount of fluorescent dye into the AC system. Refrigerant leak in Town and Country can be caused by leaking O-ring seals, leaking condenser or evaporator core, or a cracked hose. If the refrigerant level goes down again quickly, it means there is probably a leak. Just have it refilled and you can drive with pleasant temperatures again. If you don’t service the AC system in your Town and Country for a long time, the refrigerant level will eventually get so low that the system loses its cooling capacity. Ideally, the refrigerant should never leak in a properly sealed AC system, but most car AC systems do leak small amount of refrigerant over time due to minor imperfections and will need recharging after every few years. If a system is left open and exposed to outside air and humidity for a long time, the pump on-time should be increased significantly.A low refrigerant level in your Town and Country does not necessarily mean there is a leak. Check with manufacturer's specifications. If a system has been opened for repair, a vacuum should be pulled for at least 30 minutes. By bringing a closed system into a vacuum, the boiling point is greatly reduced, and any moisture boils into a vapor that's pulled out through the vacuum pump. Performing an evacuation does not remove metal shavings from a system though, this requires a flush.Ī vacuum pump is used to draw the system to a vacuum of 29.75 "hg or greater. It blends with the hygroscopic oils used in today's R-134a systems, reducing their ability to lubricate components like the compressor. It forms a corrosive hydrochloric acid that corrodes lines, clogs screens, and damages other components in the system. Moisture in an R-134a system mixes and reacts with the refrigerant and oil in the system. Moisture and air are removed from the system with a vacuum pump to draw the system into a vacuum. When a system is severely low on refrigerant or has been opened for repair, moisture and air enter the system. After the recovery process is complete and all available refrigerant has been removed from the system, it's ready for evacuation. ![]()
