🔧 Radiator Hose - Replacement

Replacing the radiator hose on your Equinox means draining enough coolant to safely remove the old hose, swapping in the new hose and clamps, then refilling and bleeding the cooling system. This job is straightforward, but coolant is hot and under pressure, so let the engine cool fully before starting.

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

⚠️ Safety & Precautions

• Work only on a completely cool engine. Hot coolant can cause severe burns.
• Do not open the coolant cap when the engine is hot.
• Keep coolant away from pets and children; it is toxic.
• Use jack stands if you raise the vehicle. Never rely on a jack alone.
• Battery disconnect is not required for this repair.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Drain coolant to a safe level

• Use the drain pan under the radiator drain area.
• Open the radiator drain or remove the lower hose carefully enough to lower coolant level below the hose you are replacing.
• If needed, use pliers to loosen the factory clamp and slide it back.
• Drain only what you need.

Step 2: Remove the old hose

• Use hose clamp pliers or slip-joint pliers to release the hose clamps.
• Twist the hose gently to break it loose from the radiator neck and engine fitting.
• If it is stuck, use a flat-blade screwdriver carefully to help lift the hose edge free.
• Remove the hose and keep track of its routing.

Step 3: Inspect the fittings

• Check the radiator neck and engine pipe for cracks, rust, or old rubber stuck on the surface.
• Clean the sealing surfaces so the new hose sits fully in place.
• Make sure the clamp area is smooth and not damaged.

Step 4: Install the new hose

• Compare the new hose to the old one to confirm the shape matches.
• Slide the new clamps onto the hose first.
• Push the hose fully onto both fittings until it seats against the stop.
• Position the clamps on the same areas as the original clamps.
• If using spring clamps, use hose clamp pliers to place them correctly.

Step 5: Refill the cooling system

• Use a funnel to refill with DEX-COOL coolant.
• Fill slowly to reduce air pockets.
• Install the coolant cap once the system is at the correct level.

Step 6: Bleed air from the system

• Start the engine and let it idle with the heater set to full hot.
• Watch the coolant level and add more as the air purges.
• Inspect the hose and clamp areas for leaks.
• If the level drops, top it off again after the engine cools.

Step 7: Final check

• Bring the engine to operating temperature and confirm normal heat output.
• Shut the engine off and recheck coolant level after it cools.
• Make sure there are no drips under the vehicle.

✅ After Repair

• Drive the vehicle and watch the temperature gauge.
• Recheck coolant level the next day when the engine is cold.
• Inspect the hose connections again for seepage.
• If the level keeps dropping, there may be another leak in the cooling system.
