🔧 Encore - Radiator Hose Replacement

Replacing a radiator hose means safely draining some coolant, removing the old hose, and installing a new one with good clamps so it doesn’t leak. It’s important because a weak or swollen hose can burst and quickly overheat your Encore.

Difficulty Level: Intermediate | Estimated Time: 1.0-2.0 hours

Assumption: You’re replacing the upper radiator hose (most common); lower hose is similar but tighter access.

⚠️ Safety & Precautions

• ⚠️ Never open the cooling system hot; let the engine cool 2+ hours.
• ⚠️ Coolant is toxic—keep away from kids/pets and clean spills immediately.
• ⚠️ Support the vehicle with jack stands; never rely on a jack alone.
• ⚠️ Keep hands/tools clear of the cooling fan; it can run unexpectedly.
• ⚠️ Do not mix coolant types; use the correct Dex-Cool spec.
• ⚠️ Battery disconnect is not required for this job.

📋 Before You Begin

• Park on level ground, set the parking brake, and place wheel chocks behind the rear wheels.
• Let the engine cool completely (upper radiator hose should feel cool and soft).
• Set the HVAC to Heat later during bleeding; no infotainment service mode is required.
• Position a drain pan (10-quart) under the radiator area before loosening anything.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the engine cover (if equipped)

• Lift the cover straight up by hand. If it’s secured, use a 10mm socket with a 1/4" drive ratchet to remove fasteners.
• Tip: Pull upward evenly to avoid breaking grommets.

Step 2: Relieve pressure at the coolant reservoir

• Place a shop towel over the coolant reservoir cap.
• Slowly loosen the cap to the first stop to vent any leftover pressure, then remove it fully.

Step 3: Raise the front (helps access and draining)

• Use a floor jack (rated 3-ton minimum) to lift the front and set it securely on jack stands (rated 3-ton minimum).

Step 4: Remove the lower splash shield (if needed for access)

• Use a trim clip removal tool for plastic clips.
• Use a 7mm socket or 8mm socket with a 1/4" drive ratchet to remove small bolts/screws (varies by shield).

Step 5: Drain enough coolant to get below hose level

• Place the drain pan (at least 10-quart) under the radiator lower area.
• If your Encore has a drain cock, open it carefully with a flat-blade screwdriver. If not, you can drain by loosening the lower hose clamp slightly (messier).
• Drain about 1-2 quarts—just enough so coolant won’t pour out when the hose comes off.

Step 6: Remove the old radiator hose

• Locate the hose ends (radiator side and engine/thermostat housing side). Use a work light for visibility.
• If you have spring clamps, squeeze them with hose clamp pliers and slide the clamp back on the hose.
• If you have worm-gear clamps, loosen using a flat-blade screwdriver (or 7mm socket with a 1/4" drive ratchet).
• Twist the hose to break it free. If it’s stuck, carefully work a pick tool between the hose and fitting to release it. A pick tool is a small hook used to break the seal without prying hard.
• Pull the hose off and aim it into the drain pan to catch remaining coolant.

Step 7: Prep the fittings and compare parts

• Wipe the radiator neck and engine fitting with shop towels until clean and smooth.
• Compare the new hose to the old one (same bends/length and same inside diameter).
• Slide the new radiator hose clamps onto the new hose before installing.

Step 8: Install the new radiator hose and position clamps

• Push the new hose fully onto the radiator fitting until it bottoms out.
• Push the other end fully onto the engine fitting.
• Position clamps behind the raised bead on each fitting (this bead prevents blow-off).
• If using worm-gear clamps, tighten with a flat-blade screwdriver or 7mm socket until snug—do not crush the plastic radiator neck.
• Tip: Align clamps so you can re-tighten later.

Step 9: Reinstall splash shield and lower the vehicle

• Reinstall the shield using the 7mm socket/8mm socket and trim clip removal tool (for clips).
• Lower the vehicle from the jack stands using the floor jack.

Step 10: Refill coolant and bleed air

• Insert a funnel with long neck into the reservoir.
• Fill with Dex-Cool coolant (50/50 premix) to the proper level line.
• Start the engine and set the HVAC to maximum heat (this opens the heater core to help purge air).
• Let it idle until warm. Watch the coolant level and add as it drops.
• When the thermostat opens (upper hose gets hot), you may see bubbles—keep topping off until bubbles slow down.
• Install the reservoir cap once the level stabilizes.

Step 11: Check for leaks

• With the engine idling, inspect both hose ends using a work light.
• Shut the engine off and re-check clamp tightness once it cools.

✅ After Repair

• Do a short test drive (10-15 minutes), then re-check coolant level after the engine cools fully.
• Look under the Encore for drips and re-check the hose ends for wetness.
• If the temperature gauge runs hotter than normal or heat blows cold, you likely still have air trapped—repeat the bleed step.
• Dispose of old coolant properly (many parts stores accept it).
