Coolant Level Sensor – 577.46316 or 0693316000

The rTech Black Label RT6316 Coolant Level Sensor is a heavy-duty replacement designed for compatible commercial truck coolant reservoir systems.

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

A properly functioning coolant level sensor helps provide the vehicle with the information needed to identify a low-coolant condition, making it an important part of cooling-system monitoring and preventative fleet maintenance.

Built for demanding commercial service, the RT6316 features a 2-pin electrical connection and direct-fit probe configuration for compatible Freightliner reservoir systems.

Built for uptime. Built for serious trucks.

Why Coolant Level Monitoring Matters

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

Proper coolant-level monitoring helps support:

• Early identification of low-coolant conditions
• Cooling-system monitoring
• Driver awareness
• Preventative fleet maintenance
• Reduced risk of continued operation with inadequate coolant 
  

The sensor doesn't prevent a coolant leak or replace regular cooling-system inspections. Its job is to provide the vehicle's monitoring system with coolant-level information.

For a working fleet, catching a low-coolant condition early can make a significant difference.
