🔧 Expedition - Radiator Hose Replacement

Replacing a radiator hose stops coolant leaks and prevents overheating. The job is mainly removing the old hose, installing the new one with good clamps, then refilling and bleeding air from the cooling system.

Difficulty Level: Intermediate | Estimated Time: 1.0-2.5 hours

Assumption: you’re replacing either the upper or lower radiator hose (steps show both).

⚠️ Safety & Precautions

• ⚠️ Never open the coolant cap on a hot engine; hot coolant can spray and burn you.
• ⚠️ Support the SUV with jack stands before going underneath; never rely on a floor jack alone.
• ⚠️ Keep coolant away from kids/pets; it’s toxic and attracts animals.
• ⚠️ Wear gloves and safety glasses; spring clamps can snap and coolant splashes happen.
• 🔋 Battery disconnect is not required for this repair.

📋 Before You Begin

• Park on level ground, set the parking brake, and chock the rear wheels.
• Let the engine cool fully (at least 2–3 hours). The upper radiator hose should feel cool.
• Set your drain pan under the radiator area before loosening anything.
• If doing the lower hose, raise the front with a floor jack and support with jack stands.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Depressurize the cooling system

• Slowly loosen the coolant cap on the degas bottle (coolant reservoir) to the first “stop” to release any leftover pressure.
• Remove the cap fully once you confirm there’s no hiss or pressure.
• If it hisses, wait longer to cool.

Step 2: Drain enough coolant to get below the hose level

• Place a drain pan (at least 3-gallon) under the radiator.
• Use a flathead screwdriver (or hand-turn if equipped) to open the radiator drain cock (petcock) slightly and drain coolant.
• Drain until the coolant level is below the hose you’re replacing (upper = a little; lower = more).
• Close the drain cock snugly (do not overtighten plastic).

Step 3: Remove covers/air ducting if it blocks access

• If a plastic shield or intake duct blocks the hose, remove clips with a trim clip removal tool.
• Loosen any band clamps with an 8mm nut driver and move the duct out of the way.

Step 4: Remove the radiator hose clamps

• Most factory clamps are spring clamps. Use hose clamp pliers (specialty) to squeeze the clamp ears and slide the clamp back on the hose.
• If you have a worm-gear clamp (screw type), loosen it with an 8mm nut driver or flathead screwdriver.
• Put a rag under the joint for drips.

Step 5: Break the hose loose (without damaging the radiator neck)

• Twist the hose by hand to break it free.
• If it’s stuck, use channel-lock pliers to gently twist (don’t crush the radiator neck).
• If still stuck, carefully slide a pick tool (small hook) (specialty) between hose and fitting to break the seal, then twist again.
• Pull the hose off the radiator end, then off the engine/thermostat end.

Step 6: Clean and inspect the hose connections

• Wipe the radiator neck and engine neck with shop rags.
• Use a flashlight to check for cracks, heavy corrosion, or a broken “bead” (the raised lip that helps hold the hose).
• If a neck is damaged, don’t reassemble—coolant leaks can come back immediately.

Step 7: Install the new hose and position the clamps

• Slide the clamps onto the new hose before installing it.
• Push the hose fully onto the radiator neck and the engine neck until it bottoms out.
• Position the clamp behind the bead/lip on the fitting (not on the very edge).
• For spring clamps: use hose clamp pliers (specialty) to release the clamp into place.
• For worm clamps: tighten with an 8mm nut driver until snug. Do not overtighten; it can cut the hose.

Step 8: Reinstall any ducts/covers you removed

• Reinstall air ducting and tighten with an 8mm nut driver.
• Reinstall splash shields/clips using a trim clip removal tool as needed.

Step 9: Refill coolant

• Use a funnel to refill the degas bottle with Ford-spec, Orange coolant equivalent 50/50 premix to the MAX line.
• If you drained a lot (lower hose), you may need several gallons total.

Step 10: Bleed air and check for leaks

• Start the engine and set the heater to full hot (this helps circulate coolant through the heater core).
• Let it idle while watching the new hose connections with a flashlight.
• As the engine warms up, the coolant level may drop—add coolant as needed using a funnel.
• When warm, gently squeeze the upper hose (with nitrile gloves) to help burp trapped air.
• Shut the engine off, let it cool completely, then recheck the level and top off to the MAX line.

✅ After Repair

• Take a short 10–15 minute drive, then park and look underneath for drips.
• After a full cool-down, recheck the degas bottle level and top off if needed.
• Inspect the clamp positions again; a clamp that’s not behind the bead will leak.
• Dispose of old coolant properly (many parts stores accept waste fluids).
