Frequently Asked Questions
Find answers to common questions about torque specifications
Q1 What is the refrigerant type used in the 1985-1989 Acura Integra HVAC system?
What is the refrigerant type used in the 1985-1989 Acura Integra HVAC system?
The 1985-1989 Acura Integra HVAC system uses R-12 (Freon) refrigerant, which was standard for vehicles of that era. Ensure proper handling and disposal procedures are followed due to environmental regulations.
Q2 How do I check the HVAC system's compressor efficiency?
How do I check the HVAC system's compressor efficiency?
To check the compressor efficiency, measure the refrigerant pressure at the compressor inlet and outlet. The inlet pressure should be around 30 psi and the outlet pressure should be approximately 150 psi under normal operating conditions.
Q3 What is the recommended maintenance interval for the HVAC system?
What is the recommended maintenance interval for the HVAC system?
It is recommended to inspect and service the HVAC system every 12 months or 12,000 miles. This includes checking refrigerant levels, inspecting the compressor, and cleaning the condenser and evaporator coils.
Q4 How can I diagnose a HVAC system that is not cooling properly?
How can I diagnose a HVAC system that is not cooling properly?
Diagnose by checking refrigerant levels, inspecting for leaks, and ensuring the compressor and condenser are functioning correctly. Use a pressure gauge to verify refrigerant pressure is within the range of 30 psi at the inlet and 150 psi at the outlet.
Q5 What are the safety precautions when servicing the HVAC system?
What are the safety precautions when servicing the HVAC system?
Always wear protective gloves and eyewear when handling refrigerant. Ensure the system is depressurized before servicing. Avoid direct contact with refrigerant and use proper ventilation to prevent inhalation of harmful gases.
