📋 Kit Contents

• 1 x complete transmission oil-cooler service package 21152060
• The public catalogue does not separately itemise every cooler, seal and fitting packaged within 21152060
• Related hoses 21148614, cooler 21112814, clamps 21149056, bracket kit 21159822 and adapter kit 21162171 are separate catalogue items unless the sealed Volvo package specifically includes them

🔌 Function

Removes heat from the reversing-gear oil so hydraulic pressure, clutch operation and bearing lubrication remain stable under sustained marine load.

⚠️ Common Signs of Failure

• High transmission-oil temperature
• Coolant contamination or milky transmission oil
• External corrosion, tube leakage or restricted cooling flow
• Gear engagement deteriorates as the oil becomes hot
• Pressure testing reveals leakage between oil and water circuits

🛠️ Service Notes

• Specific to the HS63A gearbox - the similar-looking kit 21150947 covers the HS25A and HS45A gears instead, so match by transmission model rather than by kit description
• A later service replacement for earlier HS63 cooler arrangements - confirm the connection and bracket layout against your actual gearbox before fitting, since Volvo Penta notes this varies by revision
