Do not change the coolant until you read and understand the material found in the Special Publication, SEBU6250, "Caterpillar Machine Fluids Recommendations". Failure to do so could result in damage to the cooling systems components. |

Mixing 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 see the topic Extended Life Coolant (ELC) in the Special Publication, SEBU6250, "Caterpillar Machine Fluids Recommendations". |

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. |
If the coolant in the machine is changed to Extended Life Coolant from another type of coolant, refer to Special Publication, SEBU6250, "Cat Extended Life Coolant (ELC)" for more information.

| Illustration 1 | g00400065 |
The radiator for the tractor is located at the front of the tractor.
If the coolant is dirty or if you observe any foaming in the cooling system, drain the coolant before the recommended interval.
- Allow the engine to cool.
- Loosen the pressure cap slowly in order to release pressure. Remove the pressure cap.
- The radiator drain (1) for the tractor is located behind the oil drain (2).

Illustration 2 g00400068 - Remove the bolt (3) in order to remove the cover plate for the radiator drain on the tractor. Open the drain valve.
- Flush the cooling system with clean water until the draining water is transparent.
- Close the drain valve. Install the cover plate and the bolt.
- Add the Extended Life Coolant. Refer to 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 (.5 inches) of the bottom of the filler pipe. - Inspect the gasket of the cooling system pressure cap. If the gasket is damaged, replace the gasket.
- Install the cooling system pressure cap.
- Stop the engine.
