DIFFERENTIAL & BEVEL GEAR GP 3653456 - Caterpillar

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 specifications 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.If ELC cooling system contamination occurs, refer to Special Publication, SEBU6250, "Cat Extended Life Coolant (ELC)".This machine was factory filled with Extended Life Coolant.
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, "Caterpillar Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.

Open the access cover for the cooling system pressure cap. The access cover for the cooling system pressure cap is located on top of the machine above the left rear access panel.
Slowly loosen the cooling system pressure cap in order to release pressure. Remove the cooling system pressure cap.Note: Refer to Operation and Maintenance Manual, "General Hazard Information" for information that pertains to containing fluid spillage.
Open the drain valve that is on the bottom of the radiator. The drain valve can be reached through the small access hole that is located next to the drain hose on the underside of the machine. Allow the coolant to drain into a suitable container.Note: Dispose of drained fluids according to local regulations.
Flush the cooling system with clean water until the draining water is clean.
Close the drain valve.
Add the Extended Life Coolant. See Operation and Maintenance Manual, "Capacities (Refill)".
Start the engine. Operate the engine without the cooling system pressure cap until the water temperature regulator opens and the coolant level stabilizes.
Maintain the coolant level within 13 mm (0.5 inch) of the bottom of the filler pipe.
Check the gasket of the cooling system pressure cap. If the gasket is damaged, replace the pressure cap.
Install the cooling system pressure cap and close the access cover for the cooling system pressure cap.
Stop the engine.
Open the small storage compartment that is located on the floor in front of the engine compartment.

If additional coolant is necessary, remove the reservoir cap on top of the coolant reservoir and add the appropriate coolant solution.
Install the reservoir cap.
Close the small storage compartment.
Close the left rear access panel and install the bolts for the left rear access panel.
