How to Recharge an Air Conditioner in a 2002 Suzuki Xl7

by Richard Ristow

While Suzuki is primarily known as a motorcycle manufacturer, it also produces a line of cars and sports utility vehicles. These vehicles feature air conditioners that essentially operate the same way as other makes and models. The 2002 Suzuki X17, for instance, uses R134a Freon, and the air conditioner's internal components feature high and low pressure aluminum pipes. Recharging the X17's R134a levels is just as easy as it is for other vehicles. If not done, the Suzuki's air conditioner will eventual deplete its Freon, and the air conditioner will not produce cold air.

Park the X17 on flat ground. Make sure the Suzuki's emergency brake is fully engaged. Move the vehicle's gear shift to the proper designation, based on transmission type. Automatics should be in "Park." Standards need to be in neutral.

Walk around the Suzuki, and open all the doors. You also will be running the vehicle's air conditioner. If refrigerated air builds up within the Suzuki, the air conditioner could mistakenly switch itself off. If you do not wish to have the doors open, you can always roll down all the windows.

Open the Suzuki's hood, and find the low-pressure service outlet. You will find this port on a wide aluminum pipe connecting the sport utility vehicle's compressor to its drier. It resembles a thicker version of a tire's valve stem, and it features either a blue or a black dust cap. Undo the dust cap, and remove it.

Connect your R134a recharging kit to the Suzuki's low-side pressure outlet. Leave the kit in an engine location that is nowhere near belts or fans. You do not want moving engine parts jostling a pressurized R134a canister.

Start the X17's engine. Wait till the engine warms up, and then power up the air conditioner. The air blower must be set to the highest capacity. Also, set the air temperature to the coldest level. Exit the X17's passenger compartment, and return to the engine.

Open the R134a kit's valve by turning the nozzle atop the R134a Freon canister. Let 60 seconds worth of Freon charge into the system. This will be accompanied by a "rushing" gas noise. Do not be concerned. It's a normal sound for this process.

Turn the nozzle, and close the valve. Let the Suzuki's air conditioner rest for 60 seconds. The air blower will move the new Freon through the pipes and system components. Continue to add Freon in 60-second "On-and-off" increments.

Place a thermometer into the Suzuki's duct at the center of the air conditioning system. Monitor the temperatures reported by the thermometer. Once 40 degrees Fahrenheit has been reached, the process is over. When set to it's coldest, an air conditioner produces refrigerated air that will measure 40 degrees.

Pull the thermometer from the Suzuki's center air conditioning duct. Detach the R134a recharging kit from the sport utility vehicle's low-side pressure outlet. Keep the air conditioning and engine running for 10 additional minutes. During that time, the system's blower will fully spread the Freon throughout the entire air conditioning system. Then, turn the air conditioner off. Follow that by shutting the engine down.


  • check During the recharging, the R134 Freon canister will become extremely cold to the touch. For both safety and comfort, wear winterized gloves.
  • check Eye protection should be worn at all times.
  • check Store leftover Freon in a dark place with all the kit's parts still attached to the R134a Freon canister.


  • close R12 Freon is not intended for the 2002 Suzuki X17's usage. Do not buy an R12 recharging kit, and do not attempt to add it to the Suzuki's air conditioner. R12 and R134a do not mix and actively trying to mix them will damage the R134a system.
  • close Very hot weather will influence the system's internal temperature. On those days, the system could become consistent anywhere between 60 and 40 degrees when fully charged.
