Frequently Asked Questions
Find answers to common questions about torque specifications
Q1 What is the refrigerant type and capacity for the 2001-2003 Acura CL HVAC system?
What is the refrigerant type and capacity for the 2001-2003 Acura CL HVAC system?
The 2001-2003 Acura CL HVAC system uses R-134a refrigerant. The total system capacity is approximately 21.2 ounces (600 grams). Always refer to the under-hood label for exact specifications.
Q2 How do I diagnose a weak airflow from the HVAC system?
How do I diagnose a weak airflow from the HVAC system?
Weak airflow can be caused by a clogged cabin air filter, a malfunctioning blower motor, or obstructed air ducts. The cabin air filter should be inspected and replaced every 15,000-30,000 miles. The blower motor resistor or control module may also require testing and replacement if necessary.
Q3 What is the procedure for recharging the AC system?
What is the procedure for recharging the AC system?
To recharge the AC system, first evacuate the system using a vacuum pump to remove moisture and air. Then, recharge with the specified amount of R-134a refrigerant (21.2 ounces). Use a manifold gauge set to ensure proper high and low-side pressures, typically 25-45 psi on the low side and 200-250 psi on the high side when the system is running.
Q4 Why is my AC blowing warm air?
Why is my AC blowing warm air?
Warm air from the AC can result from low refrigerant levels, a faulty compressor, a clogged expansion valve, or a malfunctioning blend door actuator. Check refrigerant levels first and inspect for leaks. If refrigerant levels are normal, further diagnostics on the compressor and blend door system are required.
Q5 How do I reset the HVAC control module?
How do I reset the HVAC control module?
To reset the HVAC control module, disconnect the negative battery terminal for 10-15 minutes. Reconnect the terminal and start the vehicle. Allow the system to recalibrate. If issues persist, a professional diagnostic scan tool may be required to reset or reprogram the module.
