🔌 Function

Carries cooling fluid through the hydraulic power-control or transmission cooling circuit, preventing excessive fluid and component temperature.

⚠️ Common Signs of Failure

• Fluid or coolant leakage at hose ends
• Cracked, hardened or swollen hose
• Chafing from incorrect routing
• Hose collapse restricting cooling flow
• Over-temperature warning from the hydraulic or transmission system
• Repeated clamp loosening or damaged connection necks

🛠️ Service Notes

• Fit the hose dry onto clean, smooth stubs and push it fully onto the spigot so the clip lands behind the bead; do not use grease or sealant to help it on
• Keep the original routing and bend radius and use the correct clips, tightened evenly — a hose that is kinked, stretched or pulled to fit will fail early
• Check the stubs for corrosion, pitting and burrs while the hose is off, and clear any scale or debris out of the system
• Keep the hose away from hot surfaces and anything that can chafe it, and support long runs as they were originally clipped
• Refill, vent and run the engine to temperature, then re-check every joint and re-tighten the clips once the hose has bedded in
