303.11.0084.04 Solenoid Coil for Heavy-Duty Fuel Systems

What is a solenoid coil repair kit?

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.

Vehicle and engine compatibility

This component is compatible with N14 engines used across a wide range of heavy commercial vehicle brands including Kenworth, Peterbilt, Freightliner, International, Ford Trucks, Volvo, Sterling, and Western Star. It is also fitted to Scania trucks. These kits ensure that the electrical integrity of the fuel delivery system remains intact during routine maintenance.

Installation and maintenance

When performing installation, technicians should verify the socket configuration and ensure all seals are seated correctly to prevent leaks. Proper selection ensures the electrical resistance matches the requirements of the engine control unit. Maintaining these components helps prevent sudden engine shutdown caused by failing solenoid windings.
