You can buy a charge kit from your local auto parts store and follow directions but if it needs a charge it must have a leak. Have the leak repaired first. This is best done by a garage that does AC work.
Find your ac compressor. Follow the larger hose. Up to the metering device outlet, that's your low pressure side.

To add Freon to a 2000 Isuzu Trooper, first, locate the low-pressure service port on the AC system, which is typically found on the larger diameter aluminum line. Attach the AC refrigerant can to the service port using a can tap, ensuring it's secure. Start the vehicle and turn on the AC to the maximum setting, then gradually open the can tap to allow Freon to flow into the system. Monitor the pressure gauge on the can to avoid overcharging, and stop when the system reaches the appropriate pressure level.

The 1988 Isuzu Trooper uses R12 refrigerant for its air conditioning system. However, due to the phase-out of R12 due to environmental concerns, many owners may choose to retrofit the system to use R134a, which is more environmentally friendly. If you decide to retrofit, it's essential to ensure that the system is properly modified and that any necessary components are replaced to accommodate the new refrigerant.
