# 21106502 Hose | Genuine Volvo Penta Part

## 🔧 Product Description

A genuine Volvo Penta moulded seawater hose used in the V8 gasoline-engine thermostat-housing circuit supplying the exhaust elbows. In the V8-270/300/320 C and CE cooling diagrams, this hose occupies a defined branch alongside hoses 21106504 and 21106506. Its formed shape maintains flow and clearance around the thermostat housing, fuel-pump area and exhaust components.

## 🚤 Compatibility

-   **Engine Family:** V
-   **HP Range:** 225-320 HP

## ⚙️ Key Features

-   Moulded seawater hose for the V8 thermostat-housing/exhaust-elbow circuit
-   Position-specific bends avoid the exhaust manifolds and fuel-system components
-   Marine-grade reinforced hose withstands suction, pressure and warm seawater
-   Correct end diameters match the original thermostat-housing and pipe connections
-   Separate part from companion hoses 21106504 and 21106506
-   Engine type: Volvo Penta V8 gasoline marine engine seawater-cooling system

## 🔌 Function

Routes raw cooling water from the thermostat-housing circuit toward the assigned exhaust-elbow or cooling branch.

## ⚠️ Common Signs of Failure

-   Seawater leakage at the hose ends
-   Soft or internally collapsed hose restricting exhaust cooling
-   Heat damage near the exhaust manifold
-   Cracking or salt deposits around clamp positions
-   Exhaust-elbow overheating or reduced cooling-water discharge

## 🛠️ 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
