MANIFOLD-EXHAUST 1834332 - Caterpillar

Engine hood and engine hood parts can be hot while engine is running or immediately after engine shutdown. Hot parts or hot components can cause burns or personal injury. Do not allow these parts to contact your skin, when engine is running or immediately after engine shutdown. Use protective clothing or protective equipment to protect your skin.
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.
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.
Note: This machine was filled at the factory with Cat Extended Life Coolant.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".
Open the cooling system access door.

Slowly loosen the pressure cap (1) that is on the coolant reservoir to release pressure from the cooling system.
Remove the pressure cap.
Inspect the o-ring of the cooling system pressure cap. If the o-ring is damaged, replace the pressure cap.Note: Refer to Operation and Maintenance Manual, "General Hazard Information" for information that pertains to containing fluid spillage.
Open the cooling system access door on the left side of the machine.
Open the draincock valve and allow the coolant to drain into a suitable container. The draincock valve is on the bottom of the radiator.
Flush the cooling system. Follow Step 7.a through Step 7.h to flush the cooling system.
Close the drain valve.
Fill the cooling system with clean water.
Install the pressure cap.
Start the engine and run the engine until the engine reaches operating temperature.
Stop the engine and allow the engine to cool.
Loosen the pressure cap slowly to relieve any pressure in the cooling system.
Open the drain valve that is on the bottom of the radiator and allow the coolant to drain into a suitable container.
Flush the radiator with clean water until the draining water is transparent.
Close the drain valve.
Add the Extended Life Coolant. Refer to the following topics:
Special Publication, SEBU6250, "Caterpillar Machine Fluids Recommendations"
Operation and Maintenance Manual, "Capacities (Refill)"
After the cooling system has been filled, perform the following procedures during initial start-up:
Start the engine without the filler cap.
Run the engine
