303.04.0029.02 Repair Kit for ECAS Solenoid Valves

What is an ECAS solenoid valve repair kit?

An ECAS solenoid valve repair kit is a service set designed to renew the worn elements inside the solenoid valve blocks of an electronically controlled air suspension system. This kit allows for the efficient maintenance of the pneumatic components that manage air bellows to maintain constant chassis height. By replacing internal elements, technicians can restore system performance without the need for a complete valve block replacement.

Vehicle and engine compatibility

This repair kit is compatible with Volvo models including FM, FMX, VHD, NH12, B11R, FH13, FH16, VNL, FM11, FM12, FM10, and B13R engines such as D13, D12, D16, and D11 series. It also fits Mack Granite and Pinnacle models, as well as Renault Trucks Premium, Magnum, and Kerax series. These components are also fitted to Scania trucks.

Installation and maintenance

For optimal performance, technicians should inspect the solenoid block for signs of air leakage or delayed level response. Regular maintenance of these sealing elements helps prevent vehicle sagging while parked. When performing installation, ensure all surfaces are clean and that new seals are seated correctly to maintain system integrity.

Troubleshooting and service guidance

Regular inspection of the suspension system can prevent unexpected downtime for heavy commercial vehicle fleets. Using high-strength components during service ensures long-term reliability in demanding operating environments.
