EXCERPT:
Remove & Install Aftercooler & Aftercooler Core
Fluid Spillage Containment
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the machine. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to "Tools And Shop Products Guide", NENG2500 for tools and supplies suitable to collect and contain fluids in Caterpillar machines. Dispose of fluids according to local regulations and mandates.
1. Drain the coolant from the aftercooler core and water lines into a suitable container for storage or disposal.
2. Remove bolt (5), the washer and the spacer.
3. Remove bolt (2) and the washer from the clip.
4. Disconnect fuel line (1). Cap and plug all openings immediately.
5. Remove two bolts (3) and remove elbow (4).
