Description
Direct-fit solenoid valve for heavy-duty truck A/C systems, marked 2601020. This 12V normally-closed solenoid valve uses a 6 male SAE flare insert with O-ring seal and is compatible with both R12 and R134a refrigerants. Commonly used to control refrigerant flow to auxiliary or sleeper cab cooling systems on heavy-duty trucks.
When to Replace a Solenoid Valve
Use this part when:
- Sleeper unit A/C does not engage despite proper system pressure
- Refrigerant flows continuously without solenoid control
- Valve coil is burned or non-responsive to electrical signal
- System loses cooling after solenoid failure
