🔧 Radiator Hose - Replacement

Replacing a radiator hose on your F-150 means draining some coolant, removing the old hose and clamps, then installing the new hose and refilling the cooling system. On the 3.5L EcoBoost, the hoses run tight around the front of the engine, so work slowly and keep an eye on nearby hot and sharp parts.

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

⚠️ Safety & Precautions

• Let the engine cool completely before opening the cooling system. Hot coolant can cause severe burns.
• Do not remove the radiator cap or reservoir cap when the engine is hot.
• Use jack stands if you raise the truck. Never work under a truck supported only by a jack.
• Keep coolant away from pets and children. Used coolant is toxic.
• If the hose is near the fan shroud or accessory drive, keep hands clear of moving parts.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Drain coolant to below the hose level

• Place the drain pan under the radiator.
• Open the radiator drain valve or remove the lower hose carefully if needed.
• Drain enough coolant so the hose you are replacing is below the coolant level.
• Work with a cold engine only.

Step 2: Remove access components if needed

• If the hose is hard to reach, remove the intake tube or nearby covers using a 10mm socket and ratchet.
• Set fasteners aside in order so they go back in the same place.

Step 3: Remove the old hose

• Use hose clamp pliers or pliers to compress the spring clamps.
• Slide the clamps back on the hose.
• Twist the hose gently to break it loose, then pull it off the fittings.
• If it is stuck, use a flat-blade screwdriver carefully to lift the hose edge.
• Do not pry on plastic necks.

Step 4: Inspect the fittings

• Check both hose ends for cracks, rust, or residue.
• Clean the fittings with a shop towel.
• Make sure the old hose did not leave rubber stuck to the pipe.

Step 5: Install the new hose

• Slide the clamps onto the new hose before installing it.
• Push the hose fully onto both fittings until it seats against the stop.
• Position the clamps in the same spot as the originals using hose clamp pliers or pliers.
• Make sure the hose is not twisted or rubbing on anything.

Step 6: Reassemble removed parts

• Reinstall any intake tube or covers using the 10mm socket and ratchet.
• Make sure all clips and fasteners are fully seated.

Step 7: Refill the cooling system

• Close the drain valve if it was opened.
• Use a funnel to refill with Ford-approved coolant mixed with distilled water if required by the coolant type.
• Fill the degas bottle to the proper mark.
• Fill slowly to reduce trapped air.

Step 8: Bleed air from the system

• Start the engine with the cap on and let it idle.
• Watch the coolant level and add more as it drops.
• Turn the heater to full hot and the blower on low.
• Let the engine reach operating temperature and check for bubbles.
• Install the cap securely once the level stabilizes.

Step 9: Check for leaks

• Inspect both hose ends, clamp areas, and the radiator for leaks.
• Shut the engine off and recheck the coolant level after it cools.

✅ After Repair

• Drive the truck short distance and watch the temperature gauge.
• Recheck coolant level the next day when the engine is cold.
• Look for dried coolant residue around the hose ends after a few heat cycles.
