Warm air blowing from the air conditioner in your Acura Integra is frustrating. Fortunately, if lack of refrigerant is the problem, recharging the system will correct the problem. In most models, you can use an R134 recharge kit from your local auto parts store.
Instructions
Prepare for Recharging
- 1
Inspect your air conditioning lines for damage. Some auto parts stores have kits that will help you to find leaks in the system and possibly seal small leaks. If you see any visible damage, take your Integra to a professional to recharge the air conditioning system with Freon.
2Locate the Low Pressure Side port. You can find this under the hood of the car. It will be near the front grill. When you are looking from left to right, the port will be almost directly in the center. Take off the port cap and set it aside.
3Determine if your car uses R134 or R12 Freon. R134 compatible models will have quick connect port valves. Models made before 1995 may use the old R12 Freon. If this is the case, you must have your Integra's air conditioning system retrofitted to use R134 Freon.
4Check the air conditioning system pressure using an auto air pressure gauge. Keep in mind that the car should be on with the air conditioner running full blast. If the pressure is in the normal or high range, lack of Freon isn't the problem.
Recharge the System

Attach the refill kit hose to the connector on the Low Pressure Side of the air conditioning system. Make sure you follow the manufacturer's directions.
6Open the valve on the refill hose slowly to allow the Freon to enter the air conditioning system. Keep in mind that it can take as long as 10 minutes to empty a single can of R134 into the system. Your car can hold a total of 27.4 oz. of Freon.
7Close the valve on the refill hose and remove it from the Low Pressure Side port. Remember to put the cap back on the port.
8Leave the air conditioner on for at least 30 minutes to allow the Freon to circulate through the entire air conditioning system.
