⚙️ Key Features

• Catalyst exhaust cooling-system hose
• Factory moulded bend and installed length
• Designed for raw water or coolant and exhaust-system heat
• Position-specific within the V8 manifold and elbow assembly
• Not interchangeable with adjacent hose numbers without parts list for your engine confirmation
• L=2200mm (Volvo assembly listing)
• 2 used per assembly

🔌 Function

The hose routes cooling water through the exhaust manifold, catalyst elbow or connected cooler passage and absorbs engine movement.

⚠️ Common Signs of Failure

• Water leakage
• Heat hardening or cracking
• Internal delamination or collapse
• Restricted exhaust cooling
• Overheated manifold or elbow
• Chafing against exhaust components

🛠️ Service Notes

• Fit hoses only to clean, sound spigots — take off old rubber, scale and corrosion, and renew the spigot or pipe if it is pitted, because no clamp will seal a rough sealing face
• Push the hose fully home so the clamp sits behind the bead or barb rather than over the end of the spigot, and fit new clamps whenever a hose is renewed
• Let the hose follow its natural bend with no kinks and no tension on either connection, clear of hot surfaces and moving parts, with chafe protection wherever it passes a bracket, edge or bulkhead
• Use the correct grade of hose for the duty, and clamp to the standard the installation demands — twin clamps are normal practice on seawater and fuel connections below the waterline
• Refill, vent and run the engine, then check every joint hot and cold and recheck the clamps after the first running period as the hose beds down
