Use Care When Handling Water Seals For Cylinder Head Spacer Plates
Usage:
All 3400 Series Truck Engines
Petroleum products can damage the rubber used in spacer plate water seals (4W1055 Seal). This damage can be caused by the use of a water soluble oil in the cooling system or by contamination during maintenance or assembly.
When petroleum products come into contact with these seals they cause the rubber to swell. This can result in extruding and eroding of the inside diameter of the seal lip.
