TUBE AS 9P8514 - Caterpillar

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.
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.
Use Caterpillar Extended Life Coolant (ELC) when you add coolant to the cooling system. See Special Publication, SEBU6250, "Caterpillar Machine Fluids Recommendations" for all cooling system requirements.Use a Coolant Conditioner Test Kit in order to check the concentration of the coolant.
Mixing ELC with other products will reduce the effectiveness of the coolant.This could result in damage to cooling system components.If Caterpillar products are not available and commercial products must be used, make sure they have passed the Caterpillar EC-1 specification for pre-mixed or concentrate coolants and Caterpillar Extender.
This machine was filled with Extended Life Coolant at the factory.If the coolant is dirty or if you observe any foaming in the cooling system, drain the coolant before the recommended interval.If the coolant in the machine is changed to Extended Life Coolant from another type of coolant, see Special Publication, SEBU6250, "Caterpillar Machine Fluids Recommendations".
Bodily injury can occur from unexpected contact with open cab doors on machines equipped with a fixed cab riser.To avoid injury, close the cab door before climbing onto the rear of the machine.
Open the left front access door. Secure the access door.

The second drain valve is located under the center of the rear frame. The access cover is held by two bolts. Remove the access cover in order to expose the drain valve. Note: Refer to the Operation and Maintenance Manual, "General Hazard Information" for information in containing fluid spillage.
Attach suitable hoses to the drain valves.
Open the drain valves, and allow the coolant to drain into a suitable container.
Illustration 5 g03820162
A drain valve is located at the side of the cylinder block. Open this drain valve in order to allow coolant to drain from the internal passages in the cylinder block.
Flush the cooling system with clean water until the draining water is clean.
Close the three drain valves. Install the access cover under the rear center part of the upper
