🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Drain the coolant

• Use a drain pan under the radiator.
• Open the radiator cap only when the engine is cold.
• Open the radiator drain using your fingers or a flat-head screwdriver, if equipped, and drain enough coolant to get below the hose level.
• Keep the coolant clean if it will be reused.

Step 2: Remove the old hose clamps

• Use hose clamp pliers (specialty) to compress the spring clamps, or use a flat-head screwdriver for screw-type clamps.
• Slide the clamps away from both ends of the hose.

Step 3: Remove the hose

• Use a pick tool to gently break the seal at each hose end if it is stuck.
• Twist the hose by hand and pull it off the radiator neck and engine pipe.
• For the lower hose, reach from below if access is tight.
• For the upper hose, work from the top of the engine bay.

Step 4: Clean the fittings

• Use shop towels to clean the radiator neck and the engine connection.
• Make sure there is no old rubber stuck on the pipe.

Step 5: Install the new hose

• Slide the new clamps onto the hose first.
• Push the hose fully onto both fittings until it seats against the stop bead.
• Position the clamps over the same spots as the originals.
• Check that the hose is not twisted.

Step 6: Secure the clamps

• Use hose clamp pliers (specialty) or a flat-head screwdriver to lock the clamps in place.
• Make sure both ends are tight and evenly seated.

Step 7: Refill and bleed the cooling system

• Use a funnel to refill the radiator with the correct coolant.
• Start the engine and let it idle with the radiator cap off until the thermostat opens and air bubbles stop.
• Top off coolant as the level drops.
• Install the radiator cap once the level stays steady.

Step 8: Check for leaks

• Use a flashlight to inspect both hose ends while the engine is warm.
• Look for drips at the radiator neck, engine pipe, and clamp areas.
