303.11.0084.03 Solenoid Coil for N14 Engines

What does a solenoid coil repair kit do?

A solenoid coil repair kit is a spare parts set used to renew the electromagnet coil on the fuel shut-off valve, injector solenoid, or feed pump metering valve in the fuel systems of heavy-duty commercial vehicles. The coil generates a magnetic field from the electrical signal sent by the engine control unit, opening or closing the valve. Due to heat, vibration, and fuel vapor, the winding insulation weakens over time; in that case, instead of replacing the entire valve, only the coil and gaskets are renewed with a repair kit.

Compatible heavy commercial vehicles

This kit is compatible with N14 engines found in various heavy commercial vehicle models, including Kenworth K100E, T300, and W900 models, as well as International 9400i and Transtar units. It is also fitted to Ford Trucks L8000 and L9000 series, Freightliner Argosy and Century Class trucks, and Peterbilt 377 or 379 models. Additionally, it serves Volvo ACL/WG units, Sterling L7500/A9500/LT9500 series, and Western Star 4900/4964 models. It is also compatible with Scania vehicles.

Installation and maintenance

When performing maintenance, technicians should verify the specific valve location and ensure the electrical socket configuration matches the existing wiring harness. Replacing only the coil and seals can significantly reduce downtime compared to full valve replacement. It is essential to check that the new coil meets the required resistance values for your specific ECU signal.

Maintenance guidance

For optimal performance, always inspect the solenoid housing for any debris or signs of overheating before installing the new coil assembly.
