Auto A/C Information - Fast Track information, tips and procedures to help troubleshoot, diagnose and repair your car's air conditioning system.
Auto A/C orifice tubes and expansion valves; changing high pressure liquid freon into low pressure refrigerant Expansion valves (often called thermostatic expansion valves) control the flow of refrigerant or freon through your A/C system. Instead of expansion valves, many auto A/C systems use orifice tubes. They do the same job and an expansion valve, but without any moving parts. Orifice tubes are manufactured with different size orifices (openings) and in different color bodies. Get details on automotive air conditioning expansion valves and orifice tubes at autoACsystems.com.
What does a dirty orifice tube look like? Every orifice tube tells a story. Removing and inspecting the orifice tube is one of the most important steps to proper diagnosis of your car's air conditioning system.
Dirty orifice tubes plug up your auto A/C system and restrict the flow of refrigerant (freon) A restriction at your orifice tube will cause the refrigerant oil to stop flowing to the compressor. That could cause premature failure of your A/C compressor and a very expensive repair. Also see details of the refrigerant oil tests between Polymax2 refrigerant oil and PAG oils.
Where is the orifice tube in your auto A/C system? Orifice tubes are usually located at the inlet of the A/C evaporator. That's just before the firewall on most typical vehicles.
