🔧 Radiator Hose - Replacement

Replacing the radiator hose on your Equinox means draining enough coolant to safely remove the hose, installing the new hose with fresh clamps if needed, then refilling and bleeding the cooling system. The key is getting the clamps seated correctly and making sure no air stays trapped in the system.

Difficulty Level: Beginner | Estimated Time: 1.5-3 hours

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Drain enough coolant

• Use a drain pan under the radiator area.
• Open the drain or disconnect the lower hose slowly to lower the coolant level below the hose connection.
• Stop when the hose area is no longer full of coolant.
• Work slowly to avoid spills.

Step 2: Remove any blocked access parts

• Use a 10mm socket, ratchet, and extension bar to remove intake ducting, covers, or brackets that block access.
• If a splash shield is in the way, remove it with a trim clip removal tool and 10mm socket.

Step 3: Release the hose clamps

• Use hose clamp pliers to compress spring clamps and slide them away from the hose ends.
• If your hose uses worm-drive clamps, use a flat-blade screwdriver to loosen them.
• Note clamp positions before removal.

Step 4: Remove the old hose

• Twist the hose gently to break it free, then pull it off the radiator neck and engine fitting.
• If stuck, carefully work the edge loose with a flat-blade screwdriver without gouging the fitting.
• Inspect both ends for cracks, rust, or leftover rubber.

Step 5: Install the new hose

• Compare the new hose to the old one before installing it.
• Push the hose fully onto both fittings until it seats against the stop.
• Move the clamps into place over the hose beads.
• Torque worm-drive clamps to snug fit only; do not overtighten.
• Make sure the hose is not twisted.

Step 6: Reinstall removed parts

• Reinstall any ducts, brackets, or splash shields using the 10mm socket and trim clip removal tool.
• Torque fasteners to factory specification if a label or service spec is available.

Step 7: Refill and bleed the cooling system

• Use a funnel to refill with the correct Dex-Cool compatible coolant mix.
• Fill the surge tank to the proper mark.
• Start the engine and let it idle with the heater set to hot.
• Watch the coolant level and add more as air escapes.
• Install the cap once the level stabilizes and bubbles stop.
• Recheck after full cooldown.
