Valve Block, Compressor Assembly: Description: Description
All pressurized air suspension components contain high pressure air (up to 220 psig). Use extreme caution when inspecting for leaks. Wear safety goggles and adequate protective clothing when inspecting or servicing the air suspension system. A sudden release of air under this amount of pressure can cause possible serious or fatal injury.
Support the vehicle by supplemental means before performing any work on the air suspension system to prevent the vehicle from changing height. Before any given component is to be serviced it must be deflated. Servicing the air suspension system without supplemental support, or with pressure in the specific component, can cause possible serious or fatal injury.
The valve block is attached to its bracket and then mounted on the air suspension compressor bracket which is located forward of the rear bumper on the right side, and is bolted to the frame. A new valve block will be supplied with the attaching screws and all necessary air line connector fittings. It can be replaced independent from the air suspension compressor assembly, although if the air compressor assembly is replaced, it will also come with a new valve block attached. If water is visible in the filter located in the air suspension hose assembly, the air suspension hose assembly and the valve block must be replaced. When replacing a valve block independently, do not detach the valve block bracket from the compressor bracket. The air lines connected to the valve block are labeled for identification during replacement.
