🔧 Radiator Hose - Replacement

Assumption: This procedure is for the upper radiator hose. If you meant the lower hose, the removal and refill steps are similar, but access is different.

The radiator hose carries hot coolant between the engine and radiator. On your S60, replacing a leaking or swollen hose helps prevent overheating and coolant loss. Use care around the cooling system because it can stay pressurized and very hot after shutdown.

Difficulty Level: Beginner | Estimated Time: 1.5-2.5 hours

⚠️ Safety & Precautions

• Let the engine go completely cold before opening the cooling system.
• Do not remove the expansion tank cap on a hot engine.
• Wear safety glasses and gloves. Coolant is slippery and can irritate skin.
• Keep coolant away from pets and children.
• Battery disconnect is not required for this repair.
• Dispose of old coolant properly.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the hose area

• Open the hood and locate the radiator hose you are replacing.
• If needed, use a trim clip tool and flat-blade screwdriver to remove the upper engine cover or intake ducting blocking access.
• Take a quick photo first.

Step 2: Relieve coolant pressure

• With the engine cold, slowly loosen the expansion tank cap by hand.
• Leave the cap off while you drain and replace the hose.

Step 3: Drain coolant to a safe level

• Place a drain pan under the radiator drain area or lower hose area.
• If your hose sits below the coolant level, drain enough coolant so the hose connection stays mostly empty.
• If equipped with a drain petcock, use a flat-blade screwdriver to open it carefully.

Step 4: Remove the old hose

• Use pliers to squeeze the spring clamps and slide them back on the hose.
• Twist the hose gently to break it free, then pull it off the radiator and engine fittings.
• If it sticks, use a flat-blade screwdriver carefully to lift the hose edge. Do not damage the necks.
• Inspect both fittings for cracks, corrosion, or old hose pieces.

Step 5: Install the new hose

• Compare the new hose to the old one for length and bend shape.
• Push the new hose fully onto both fittings until it seats all the way.
• Move the clamps into position over the hose nipples using pliers.
• Make sure each clamp sits behind the bead on the fitting.
• Clamp placement matters.

Step 6: Reassemble removed parts

• Reinstall any intake ducts, covers, or clips you removed earlier.
• If any fasteners are torque-spec limited, snug them only to factory-tight. No over-tightening.

Step 7: Refill and bleed the cooling system

• Refill the cooling system with the correct coolant mixture through the expansion tank using a coolant funnel.
• Start the engine and let it idle with the heater set to warm and the fan on low.
• Watch the coolant level and top it off as air escapes.
• When the engine reaches operating temperature, check for steady heat from the vents and no leaks at the hose ends.
• Install the expansion tank cap once the system is fully bled and the level stabilizes.

Step 8: Final leak check

• Shut the engine off and inspect both hose ends, clamps, and the radiator for seepage.
• After a full cool-down, recheck the coolant level and top off if needed.

✅ After Repair

• Drive the vehicle briefly and monitor the temperature gauge.
• Check for coolant smell, drips, or wet hose ends after the test drive.
• Recheck coolant level the next day when the engine is cold.
