Carries coolant between the after cooler and the oil cooler along a pre-formed flexible route.

⚠️ Common Signs of Failure

• Weeping or dripping at a clip, or a dried crust below a joint
• Hose gone hard and glassy, or soft and spongy when squeezed
• Cracks opening in a bend when the hose is flexed
• Bulging or ballooning under pressure
• Inner bore perished and shedding rubber into the circuit

🛠️ Service Notes

• Hose 860404 runs the same after cooler to oil cooler route but on a different fitment list covering TAMD, AD, KAD and KAMD - check the engine series, because the two are not alternatives
• The superseded number 3582722 is also carried by cover 860409 and hose 860645, so confirm what an old listing is actually calling for
