PLATE-SIDE 5243257 - Caterpillar

Contact with high pressure fuel may cause fluid penetration and burn hazards. High pressure fuel spray may cause a fire hazard. Failure to follow these inspection, maintenance and service instructions may cause personal injury or death.
If you inspect the engine in operation, always use the proper inspection procedure in order to avoid a fluid penetration hazard. Refer to Operation and Maintenance Manual, "General hazard Information".Inspect all hoses for leaks that are caused by the following conditions:
Cracking
Softness
Loose clampsReplace hoses that are cracked or soft. Tighten any loose clamps.Check for the following conditions:
End fittings that are damaged or leaking
Outer covering that is chafed or cut
Exposed wire that is used for reinforcement
Outer covering that is ballooning locally
Flexible part of the hose that is kinked or crushed
Armoring that is embedded in the outer coveringA constant torque hose clamp can be used in place of any standard hose clamp. Ensure that the constant torque hose clamp is the same size as the standard clamp. Due to extreme temperature changes, the hose will harden. Hardening of the hoses will cause hose clamps to loosen. This can result in leaks. A constant torque hose clamp will help to prevent loose hose clamps.Each installation application can be different. The differences depend on the following factors:
Type of hose
Type of fitting material
Anticipated expansion and contraction of the hose
Anticipated expansion and contraction of the fittingsReplace the Hoses and the Clamps
Refer to the OEM information for further information on removing and replacing fuel hoses (if equipped).The following text describes a typical method of replacing coolant hoses. Refer to the OEM information for further information on the coolant system and the hoses for the coolant system.
Pressurized System: Hot coolant can cause serious burns. To open the cooling system filler cap, stop the engine and wait until the cooling system components are cool. Loosen the cooling system pressure cap slowly in order to relieve the pressure.
Stop the engine. Allow the engine to cool.
Loosen the cooling system filler cap slowly in order to relieve any pressure. Remove the cooling system filler cap. Note: Drain the coolant into a suitable, clean container. The coolant can be reused.
Drain the coolant from the cooling system to a level that is below the hose that is being replaced.
Remove the hose clamps.
Disconnect the old hose.
Replace the old hose with a new hose.
Install the hose clamps with a torque wrench. Note: For the correct coolant, see this Operation and Maintenance Manual, "Fluid Recommendations".
Refill the cooling system. Refer to the OEM information for further information on refilling the cooling system.
Clean the cooling system filler cap. Inspect the cooling system filler cap's seals. Replace the cooling system filler cap if the seals are damaged. Install the cooling system filler cap.
Start the engine. Inspect the cooling system for leaks.
