SERIES 60 SERVICE MANUAL 1.1.3.2 Testing the Cylinder Block (Leak-Marker Pressure) When a large water tank is not available, or when it is desired to check the block for cracks without removing the engine from the vehicle cylinder block, leak-marker pressure testing may be used. However, it is necessary to remove the cylinder head, oil cooler, and oil pan. 1. Install cylinder liners with new seal rings and crevice seals. Refer to section 1.23.3. Seat the liners firmly in the block counterbores with cylinder liner installation tool (J–35597–A). 2. Install two metric eye bolts (J–35595) in the head bolt holes at opposite ends of the block. See Figure 1-10. 3.
Fill the water jacket with a mixture of water and 3.8 liters (1 U.S. gallon) of permanent-type antifreeze. The antifreeze will penetrate small cracks and its color will aid in detecting their presence. 4. Install the cylinder block test strips and rings. See Figure 1-10. 5. Install the bolts through the strips and into the cylinder block. Torque the bolts on the ring strips to 230-237 N·m (170-175 lb·ft). Torque the bolts on the outside strips to 14 N·m (10 lb·ft). 6. Install the water inlet cover plate (J–36223–7A, part of tool set J–36223–D). See Figure 1-11. Use the bolt supplied with the tool to secure it to the cylinder block. NOTE:
At the base of each liner, the space between upper and lower liner seals is vented to the block surface, on the left side. Any coolant leakage past the upper seal is drained to the outside rather than into the crankcase, and is easily detected by a visual inspection. All information subject to change without notice.
