PLATE-STRIKER 3599735 - 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, "Caterpillar Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.
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.
Note: This procedure pertains only to Caterpillar Diesel Engine Antifreeze/Coolant (DEAC). This does not pertain to machines that are shipped from the factory with Extended Life Coolant (ELC). Also this does not pertain to the machines that are maintained with Extended Life Coolant (ELC).If the coolant is dirty or if you observe any foaming in the cooling system, drain the coolant before the recommended interval.

Open the drain valve for the engine cooling system. Drain the coolant into a suitable container. The drain valve is located on the bottom radiator tube.
Close the drain valve. Fill the system with clean water and a 6 to 10 percent concentration of cooling system cleaner.
Start and run the engine for 90 minutes. Stop the engine and drain the cleaning solution into a suitable container.
When the engine is stopped, flush the cooling system with water until the draining water is clear. Drain the water into a suitable container.
Close the drain valve.
Add the coolant solution. Add coolant slowly to help avoid air locks, 20 L (5 US gal) per minute.Reference: For additional information on the cooling system capacity, refer to the Operation and Maintenance Manual, " Refill Capacities" for the machine that is being serviced.
Start the engine. Run the engine with the cooling system pressure cap removed. Run the engine until the water temperature regulator opens and the coolant level stabilizes.Note: If you are using Caterpillar antifreeze, do not add supplemental coolant additive or change the coolant conditioner element at this time.

Maintain the coolant level to within 13 mm (0.50 inch) of the bottom of the filler pipe or to the proper level in the sight gauge.
Install the cooling system pressure cap.
Stop the engine.
