New 5L7442 Sending Unit Replacement suitable for Caterpillar Equipment

The 5L7442 sending unit is an electrical sensor that monitors fluid levels—such as fuel or coolant and sends that information to the machine’s gauge or control system. It helps operators keep track of fluid levels to avoid running low during operation.

Here’s a general guide for proper installation:

1. Turn off the machine and disconnect the power source before beginning.
2. Locate the existing sending unit on the fluid tank or reservoir.
3. Drain fluid as needed and remove any retaining hardware or connectors from the old unit.
4. Carefully extract the old sending unit and clean the mounting area.
5. Install the new 5L7442 sending unit, securing it with the appropriate fasteners.
6. Reconnect electrical connections and refill the fluid if necessary.
7. Reconnect the power source and test the system to verify accurate level readings.

The 5L7442 sending unit is used in various heavy equipment systems where fluid level monitoring is required. It’s commonly found in fuel tanks, coolant reservoirs, or other fluid storage points that need accurate electronic level feedback. Verify fitment using your machine’s service documentation before ordering. Check your manual or reach out to Propel Parts for help verifying fitment.

Yes, the 5L7442 sending unit is engineered to meet or exceed OEM specifications for reliable measurement and signal output. When replacing sensors, choose genuine or high‑quality aftermarket parts that meet or exceed OEM expectations to help ensure accurate readings and long service life.

Sending units should be checked during routine maintenance or whenever you notice inconsistent level readings. Inspect the unit and its connections for corrosion, loose wiring, or physical damage. Replace the sending unit if it no longer provides accurate feedback or shows signs of failure.

Typical indicators include:

1. Erratic or inaccurate gauge readings
2. No level reading at all
3. Sudden jumps in displayed fluid level
4. Corrosion or broken electrical connections

A quality sending unit ensures accurate fluid level monitoring, which helps operators maintain proper fluid levels and avoid downtime due to low fuel or coolant. Using genuine or high‑quality aftermarket parts that meet or exceed OEM expectations supports dependable readings, enhances reliability, and contributes to optimal equipment performance.
