🔧 Expedition - Radiator Hose Replacement

Replacing a radiator hose on your Expedition means safely draining some coolant, removing the old hose and clamps, then installing the new hose and refilling/bleeding the cooling system. This prevents overheating and coolant loss from a cracked, swollen, or leaking hose.

Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours

⚠️ Safety & Precautions

• ⚠️ Never open the coolant cap hot; let it cool fully.
• ⚠️ Support the SUV with jack stands; never rely on a jack.
• ⚠️ Coolant is toxic; keep away from kids/pets and clean spills fast.
• ⚠️ Keep hands/loose clothing away from fans and belts when running.
• Battery disconnect is not required for this job.

📋 Before You Begin

• Park on level ground, set the parking brake, and chock the rear wheels.
• Let the engine cool completely (upper hose should feel cool to touch).
• Set your HVAC to full heat later during bleeding (helps purge air).
• Take a photo of hose routing first.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise the front (if needed) and remove the lower splash shield

• Use wheel chocks at the rear wheels.
• Lift the front with a floor jack (rated 3-ton minimum) and support with jack stands (rated 3-ton minimum).
• Place a drain pan (at least 10-liter) under the radiator area.
• Remove any lower cover/splash shield fasteners using a 8mm socket, 10mm socket, 1/4" ratchet, and trim clip removal tool.

Step 2: Relieve pressure and drain enough coolant

• Slowly loosen the coolant reservoir cap to vent pressure by hand, then remove it.
• Drain coolant into the pan (use the radiator drain if accessible; if not, you’ll drain some when you crack the lower hose).
• Drain only what you need to minimize mess.

Step 3: Choose the hose you’re replacing (Upper vs Lower)

• Upper radiator hose: Usually runs from the top of the radiator to the thermostat/engine outlet area.
• Lower radiator hose: Usually runs from the bottom of the radiator to the engine water pump/inlet area (more coolant will drain).
• A constant-tension clamp is a spring clamp that keeps pressure as the hose heats/cools.

Step 4: Remove the old hose clamps

• Use hose clamp pliers (specialty) to squeeze the clamp ears and slide the clamp back onto the hose.
• If you have worm-gear clamps (screw type), loosen with a flathead screwdriver.
• Use a work light to confirm the clamp is fully clear of the fitting bead.

Step 5: Break the hose free and remove it

• Twist the hose by hand to break it loose.
• If stuck, gently work around the edge with a pick tool set (do not gouge the plastic/metal neck).
• Pull the hose off and aim it into the drain pan.
• Wipe spills using shop towels.

Step 6: Clean and inspect the hose necks

• Use shop towels to clean the radiator/engine hose neck surfaces.
• If there is stuck rubber, carefully remove it with a razor blade scraper (light pressure only).
• Inspect for cracks on plastic fittings and corrosion on metal fittings.

Step 7: Install the new hose and position clamps

• Slide clamps onto the new hose first.
• Push the new hose fully onto each fitting until it seats past the bead.
• Use hose clamp pliers (specialty) to position spring clamps in the same location as original (typically just behind the raised bead).
• If using screw clamps, tighten with a flathead screwdriver until snug (do not crush the fitting).

Step 8: Reinstall the splash shield and lower the SUV

• Reinstall the splash shield using a 8mm socket, 10mm socket, 1/4" ratchet, 6" extension, and trim clip removal tool.
• Lower the SUV safely using the floor jack (rated 3-ton minimum).

Step 9: Refill coolant and bleed air

• Use a funnel to refill the coolant reservoir with engine coolant (Motorcraft Yellow or equivalent meeting Ford spec).
• Start the engine and set HVAC to max heat (front and rear if equipped).
• Let it idle and watch the temperature gauge; keep hands clear of moving parts.
• As the engine warms, add coolant as the level drops.
• Shut the engine off, let it cool, and top off to the correct level.
• Heat cycling helps push trapped air out.

Step 10: Check for leaks

• With the engine warm, inspect both ends of the replaced hose using a work light.
• Look for seepage at clamps and drips underneath.
• Recheck the coolant level again after your first short drive.

✅ After Repair

• Verify the heater blows hot and the temperature gauge stays normal.
• Check for coolant smell/steam after a drive and inspect for wet spots.
• Recheck coolant level the next morning when cold and top off if needed.
• Dispose of old coolant properly (do not pour on ground or drains).
