Typical example
Clean the bridge and the face of the cylinder block. Apply a thin bead of Loctite 596 on the corners of the seat for the bridge. Also apply the sealant around the thread holes in the seat for the bridge. Use the following steps when you apply the Loctite 596 to the cylinder block and the bridge.
Apply a 3.0 mm (.12 inch) bead of Loctite 596 along the corner of the top recess in the cylinder block.
Install bridge (2) and the rubber seals, if equipped. The rubber seals will sit higher than the bridge when the seals are correctly installed. Use a straight edge to line up the bridge with the face of the cylinder block. Tighten socket head bolts (1) to a torque of 16 N m (12 lb
