## ⚙️ 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
