Personal injury can result from hot coolant, steam and alkali.At operating temperature, engine coolant is hot and under pressure. The radiator and all lines to heaters or the engine contain hot coolant or steam. Any contact can cause severe burns.Remove cooling system pressure cap slowly to relieve pressure only when engine is stopped and cooling system pressure cap is cool enough to touch with your bare hand.Do not attempt to tighten hose connections when the coolant is hot, the hose can come off causing burns.Cooling System Coolant Additive contains alkali. Avoid contact with skin and eyes.
Do not change the coolant until you read and understand the cooling system information in Special Publication, SEBU6250, "Caterpillar Machine Fluids Recommendations".Failure to do so could result in damage to the cooling system components.
Mixing Extended Life Coolant (ELC) with other products reduces the effectiveness of the coolant and shortens coolant life. Use only Caterpillar products or commercial products that have passed the Caterpillar EC-1 specification for premixed or concentrate coolants. Use only Caterpillar Extender with Caterpillar ELC. Failure to follow these recommendations could result in the damage to cooling systems components.
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, NENG2500, "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.
If the coolant is dirty or if you observe any foaming in the cooling system, change the coolant before the recommended interval.Park the machine on a level surface. Ensure that the parking brake is fully engaged. Lower the dump body and shut off the engine. Do not perform this procedure until the coolant has fully cooled.

The tube assembly that is located near the front of the engine must be vented in order to ensure proper filling of the cooling system. Failure to vent this tube assembly may cause the water pump to cavitate. The tube assembly may be vented in one of two ways. The tube assembly may be vented by removing the 154-9024 Sampling Valve. The tube assembly may also be vented by purchasing a 177-9343 Fluid Sampling Cap and Probe Gp from your Caterpillar dealer. Remove the dust cap from the valve . The probe may be inserted into the 154-9024 Sampling Valve in order to vent the tube assembly. The probe must be held in place.Add Extended Life Coolant to the coolant tank until the tube assembly is full.Install the 154-9024
