About the Four Seasons Pressure Switch Product Line

The Four Seasons Pressure Switch product line focuses on providing precise pressure control components for automotive HVAC systems. The Pressure Switch 37316 is part of this line, offering a trinary switch design that monitors multiple pressure thresholds to protect the A/C compressor and clutch. This ensures proper system operation by controlling fan activation and compressor engagement based on refrigerant pressure levels.

Detailed Product Description

This A/C trinary pressure switch is system-mounted and designed specifically for the INFINITI J30, providing accurate pressure monitoring with its multi-stage operation. The switch opens and closes at defined pressure points: it activates the fan at low and medium pressures and disengages the compressor at high pressure to prevent system damage. The oval female connector with pin terminals ensures a secure and weather-resistant electrical connection, while the steel body and male fitting with 3/8" x 24 thread size provide a robust mechanical fit. The inclusion of Weather Pack compatibility further enhances its durability in varying environmental conditions.

Common Applications and Issues Addressed

  • Prevents compressor damage by disengaging at high refrigerant pressure

Installation Notes and Tips

  • Verify compatibility with INFINITI J30 before installation
  • Ensure proper torque on the 3/8" x 24 male fitting to avoid leaks
  • Check connector terminals for secure and corrosion-free connections
  • Follow vehicle manufacturer guidelines for system depressurization before replacement
  • Inspect surrounding components for wear or damage during installation
