PLATE AS 1261753 - 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.
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.
Steam or hot coolant can cause severe burns.Do not loosen the filler cap or the pressure cap on a hot engine.Allow the engine to cool before removing the filler cap or the pressure cap.
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.
