🔧 Edge - Radiator Hose Replacement

This repair replaces a leaking, swollen, cracked, or soft radiator hose on your Edge. The radiator hoses carry hot coolant between the engine and radiator, so replacing a damaged hose helps prevent overheating and engine damage.

Difficulty Level: Beginner | Estimated Time: 1-2 hours

Assumption: These steps cover the upper or lower radiator hose; the lower hose may be tighter to reach from underneath.

⚠️ Safety & Precautions

• ⚠️ Never open the cooling system when the engine is hot. Hot coolant can spray out and cause severe burns.
• ⚠️ Let your Edge sit until the engine and radiator hoses are completely cool.
• ⚠️ Coolant is toxic to people and pets. Catch all coolant in a drain pan and wipe spills right away.
• ⚠️ If lifting the front of your Edge, support it with jack stands. Never work under a vehicle held only by a jack.
• ⚠️ Battery disconnect is not normally required for radiator hose replacement.

📋 Before You Begin

• Park your Edge on level ground and set the parking brake.
• Let the engine cool fully. The upper radiator hose should feel cool and soft, not hot or pressurized.
• If replacing the lower radiator hose, raise the front with a floor jack and place it securely on jack stands.
• Place a coolant drain pan under the radiator/hose area before loosening anything.
• A hose clamp plier is a tool that squeezes spring clamps evenly so they can slide off the hose safely.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove Access Covers if Needed

• Use an 8mm socket or 10mm socket with a ratchet to remove any lower splash shield fasteners blocking access to the lower hose.
• Set the fasteners aside in order so they go back in the same places.
• Take a quick photo first.

Step 2: Relieve Cooling System Pressure

• Put on safety glasses and nitrile gloves.
• Slowly loosen the coolant reservoir cap by hand only if the engine is completely cool.
• If you hear pressure escaping, stop and wait longer before continuing.

Step 3: Drain Some Coolant

• Position the coolant drain pan below the radiator hose you are replacing.
• If replacing the upper hose, drain or catch only enough coolant to lower the level below the hose connection.
• If replacing the lower hose, expect more coolant to drain when the hose is removed.
• Use clean shop towels around the area to control spills.

Step 4: Release the Hose Clamps

• Use hose clamp pliers to squeeze the spring clamp tabs together.
• Slide each clamp a few inches away from the hose end.
• If your replacement area has worm-gear clamps, use a flat-head screwdriver to loosen them.
• Do not crush plastic radiator or thermostat housing fittings.

Step 5: Remove the Old Radiator Hose

• Twist the hose gently by hand to break it loose from the fitting.
• If it is stuck, use a pick tool carefully between the hose and metal/plastic fitting to loosen the seal.
• Pull the hose off while keeping the coolant drain pan underneath.
• Do not pry hard against the radiator neck because it can crack.
• Twist first, pull second.

Step 6: Clean the Hose Connections

• Use clean shop towels to wipe the radiator and engine-side hose fittings.
• Make sure old rubber pieces are not stuck to the fittings.
• Inspect the fittings for cracks, corrosion, or rough edges before installing the new hose.

Step 7: Install the New Radiator Hose

• Slide the new radiator hose clamps onto the new radiator hose before pushing the hose onto the fittings.
• Push the hose fully onto both fittings by hand until it seats past the raised bead on each fitting.
• The raised bead is the small ridge that helps keep the hose from slipping off.
• Use hose clamp pliers to move spring clamps into their original positions behind the raised bead.
• If using worm-gear clamps, tighten them with a flat-head screwdriver until snug. Do not overtighten.

Step 8: Refill the Cooling System

• Use a funnel to add Motorcraft Yellow Prediluted Antifreeze/Coolant or Ford-approved equivalent to the coolant reservoir.
• Fill to the MAX line on the reservoir when the engine is cold.
• If using coolant concentrate, mix it only with distilled water to the proper 50/50 ratio before adding.

Step 9: Bleed Air from the Cooling System

• Leave the coolant reservoir cap off.
• Start the engine and let it idle while watching the coolant level.
• Turn the cabin heat to full hot and the blower to low using the climate controls.
• As air bubbles escape, use the funnel to add coolant and keep the level near the MAX line.
• Once the upper hose gets warm and the heater blows warm air, install the coolant reservoir cap by hand.

Step 10: Reinstall Covers and Lower the Vehicle

• If removed, reinstall the lower splash shield using an 8mm socket or 10mm socket with a ratchet.
• If your Edge was raised, use the floor jack to lift slightly, remove the jack stands, and lower it slowly.
• No radiator hose clamp torque spec is used for spring clamps; they lock by spring tension.

✅ After Repair

• Let the engine reach normal operating temperature and check for leaks at both hose ends.
• Watch the temperature gauge. Shut the engine off if it rises above normal.
• After the engine cools completely, recheck the coolant level and top off to the MAX line if needed.
• Take a short test drive, then inspect the hose and clamps again for seepage.
• Dispose of old coolant properly at a recycling center or auto parts store that accepts coolant.
