The proper way is the complete evacuation of the refrigerant from the AC system with a recovery machine, then refilling the precise amount of refrigerant by weight based on the manufacturer specifications. The DIY AC recharge kit method is considered as a quick fix, and is usually not recommended by the professionals. If the pressure is higher than the recommended values, let some refrigerant out preferably into an empty tank since releasing the refrigerant into the air is harmful for the environment and is against the law. Low side pressure values R134a vs R1234yf Ambient TemperatureĬonnect the pressure gauge to the low pressure (L) port in Trax.

Check your vehicle’s owners manual or look under the hood to find the type of the refrigerant your vehicle uses.
The pressure values based on ambient temperatures differ depending on the type of the refrigerant. Most modern vehicles use R-134a refrigerant, but newer vehicles are increasingly using R-1234yf as a more environmentally friendly replacement. So, even if you recharged your Trax AC at the recommended pressure, the system could still over pressurize when the ambient temperatures get warmer. The refrigerant pressure is affected by the outside atmospheric temperature. Note: See next section for recommended pressure values.Īmbient temperature affect on refrigerant pressure Shake the canister briefly and release the refrigerant into the system until the recommended pressure has been achieved.The recharge kit will only properly connect to the low pressure port, and will not fit the high pressure port.
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.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 Trax.

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 Trax 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 Trax 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. A low refrigerant level in your Trax does not necessarily mean there is a leak.
