SEAL GP-FACE 2925982 - Caterpillar

Pressurized system: Hot coolant can cause serious burn. To open cap, stop engine, wait until radiator is cool. Then loosen cap slowly to relieve the pressure.
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.
Topping off or mixing Cat ELC with other products that do not meet Caterpillar EC-1 specifications reduces the effectiveness of the coolant and shortens coolant service life.Use only Caterpillar products or commercial products that have passed the Caterpillar EC-1 specification for pre-mixed or concentrate coolants. Use only Extender with Cat ELC.Failure to follow these recommendations can result in shortened cooling system component life.
Reference: For information about the addition of Extender to your cooling system, refer to Operation and Maintenance Manual, "Cooling System Coolant Extender (ELC) - Add" or consult your Caterpillar dealer.If you change the coolant of a machine to Extended Life Coolant from another type of coolant, use a Caterpillar cleaning agent to flush the cooling system. After you drain the cooling system, thoroughly flush the cooling system with clean water. All of the cleaning agent must be removed from the cooling system.If an Extended Life Coolant was previously used, flush the cooling system with clean water. No other cleaning agents are required. Use the following procedure to change the cooling system coolant (ELC).
Illustration 1 g01093449The cooling system pressure cap is located on the left side of the machine on the top of the radiator.
Slowly loosen the cooling system pressure cap in order to relieve system pressure. Remove the cooling system pressure cap.
Illustration 2 g01093450
The drain valve is located at the rear of the machine under the engine compartment.
If equipped, remove the bottom guard in order to access the coolant drain valve.
Open the drain valve. Allow the coolant to drain into a suitable container.
Flush the cooling system with clean water until the draining water is transparent.
Close the drain valve. Replace the bottom guard, if equipped.
Replace the water temperature regulator. Reference: Refer to Operation and Maintenance Manual, "Cooling System Water Temperature Regulator - Replace" for the correct procedure.
Add the coolant solution. Reference: Refer to Operation and Maintenance Manual, "Capacities (Refill) " for the capacity of the cooling system.
Start the engine. Run the engine without the cooling system pressure cap until the water temperature regulator opens and the coolant level stabilizes.
Check the coolant level. Reference: Refer to Operation and Maintenance Manual, "Cooling System Level - Check" for the correct procedure.
Install the cooling system pressure cap. Stop the engine.
