⚠️ Safety & Precautions

• Let the engine cool completely before opening the cooling system. Hot coolant can cause severe burns.
• Do not remove the coolant reservoir cap on a hot engine.
• Use jack stands if you raise the vehicle. Never rely on a jack alone.
• Keep coolant away from pets and children. It is toxic.
• No battery disconnect is required for this repair.

📋 Before You Begin

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Relieve pressure and drain coolant

• Use a rag to slowly loosen the coolant reservoir cap and relieve any leftover pressure.
• Open the radiator drain if equipped, or disconnect the lower hose carefully into a drain pan.
• Drain enough coolant so the hose level is below the hose connection points.

Step 2: Remove any access parts

• If the hose is tight to reach, use a 10mm socket and ratchet to remove the air inlet duct or nearby cover.
• Set removed parts aside in order so they go back in the same place.
• Keep small clips together.

Step 3: Remove the old hose

• Use hose clamp pliers to compress the spring clamps and slide them back on the hose.
• If there are screw-type clamps, use a flat-blade screwdriver to loosen them.
• Twist the hose gently to break it free, then pull it off the radiator and engine pipe.
• If the hose is stuck, use a pick carefully to lift the hose edge without gouging the metal neck.

Step 4: Clean the hose connections

• Wipe both hose necks clean with a rag.
• Check for corrosion, cracks, or rough edges on the radiator and engine pipe.
• Replace damaged clamps now if they are weak or rusty.

Step 5: Install the new hose

• Slide the clamps onto the new hose first.
• Push the hose fully onto both ends until it seats against the stop bead.
• Position the clamps over the raised sealing area.
• Use hose clamp pliers or a flat-blade screwdriver to secure the clamps.
• Make sure the hose is not twisted.

Step 6: Reinstall access parts

• Reinstall the air inlet duct or cover with the 10mm socket and ratchet.
• Snug the fasteners only; do not overtighten plastic parts.
• Torque to manufacturer specification if any fasteners were removed.

Step 7: Refill and bleed the cooling system

• Use a funnel to refill with the correct coolant.
• Fill the reservoir to the proper level mark.
• Start the engine with the heater set to full hot.
• Let it idle and watch for air bubbles as the system purges.
• Add coolant as the level drops.

Step 8: Check for leaks

• Inspect both ends of the new hose while the engine runs.
• Shut the engine off and recheck coolant level after it cools.
• Top off if needed.

✅ After Repair

• Test-drive the vehicle and watch the temperature gauge.
• Check for coolant leaks again after the drive.
• Recheck the coolant level the next day when cold.
• If the heater blows cold or the temp rises, air may still be trapped in the system.
