303.04.0021.01 Compatible ECAS Solenoid Valve Kit

What does an ECAS solenoid valve repair kit do?

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. These kits typically include essential components such as O-rings, gaskets, diaphragms, the plunger, spring, and filter. By replacing these internal parts, technicians can restore proper pneumatic function without replacing the entire valve block assembly.

Compatible vehicles and engines

This repair kit is compatible with WABCO systems and is widely used in various heavy commercial vehicles. It is specifically suited for models including Volvo FM, FH, and VNL series, Renault Trucks Kerax and Premium, Ford Trucks Cargo models, and Mack Granite or Pinnacle. It also fits a wide range of chassis configurations from Iveco to Scania.

Installation and maintenance

To ensure correct fitment, technicians should verify the specific valve block type before installation. Since different configurations may be used depending on axle count and equipment levels, it is recommended to check the pin layout of the electrical connector and the number of ports. Maintaining these components helps prevent issues like sagging while parked or delayed level response.

Selection guidance

Consult your authorized distributor to ensure you receive the correct kit for your specific suspension architecture.
