Coolant Level Sensor – 577.46322 or 0696622002

The rTech Black Label RT6322 Coolant Level Sensor is a heavy-duty replacement designed for compatible commercial truck coolant reservoir systems.

The coolant level sensor works with the vehicle's monitoring system to detect coolant level status within the reservoir.

A properly functioning sensor is an important part of the vehicle's coolant monitoring system, helping provide the information needed for the vehicle to identify a low-coolant condition.

Built for demanding commercial service, the RT6322 features a 2-pin electrical connection and direct-fit probe configuration for compatible reservoir applications.

Built for uptime. Built for serious trucks.

Why Coolant Level Monitoring Matters

A coolant level sensor provides information to the vehicle's monitoring system about coolant level within the reservoir.

When the sensor or its circuit isn't functioning correctly, the vehicle may not receive the coolant-level information it expects.

Proper coolant-level monitoring helps support:

• Early identification of low-coolant conditions
• Cooling-system monitoring
• Preventative fleet maintenance
• Driver awareness
• Reduced risk of operating without adequate coolant 
  

A coolant level sensor does not replace regular cooling-system inspections, but it is an important part of the vehicle's monitoring system.
