Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, PERJ1017, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat® products.Dispose of all fluids according to local regulations and mandates.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Clamp assemblies MUST only be used once. Discard all clamp assemblies after use.
Bellows assemblies MUST only be used once. Discard all bellows assemblies after use.
Note: The 3508C and 3512C Engines have one aftercooler. The 3516C Engines have two aftercoolers. The following procedures describe the removal and installation of the 3516C aftercooler.
Drain the coolant from the cooling system into a suitable container for storage or for disposal.
