🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Drain coolant to a safe level

• Use a drain pan under the radiator drain area.
• Open the radiator cap only when the engine is cold.
• Open the drain petcock with your hand or a flat-blade screwdriver, depending on the style.
• Drain enough coolant so the hose level is below the hose you are replacing.
• Keep the drain pan wide and steady.

Step 2: Remove the old hose clamps

• Use pliers to squeeze the spring clamps, or use a flat-blade screwdriver for screw-type clamps.
• Slide both clamps back on the hose away from the radiator neck and engine pipe.

Step 3: Remove the old radiator hose

• Twist the hose gently by hand to break it free.
• Pull it off the radiator fitting and engine fitting.
• If it sticks, use a flat-blade screwdriver carefully under the hose lip to lift it loose.
• Do not damage the aluminum necks.

Step 4: Install the new hose

• Compare the new hose to the old one before installing.
• Push the new hose fully onto both fittings until it seats against the stops.
• Position the clamps in the same location as the originals.
• If your replacement hose uses new clamps, install them now.

Step 5: Refill coolant

• Use a funnel to refill the cooling system with the correct coolant.
• Fill slowly to reduce air pockets.
• Install the radiator cap after filling.

Step 6: Bleed air from the system

• Start the engine and let it idle.
• Turn the heater to hot and the fan on low.
• Watch the coolant level and top off as needed with a funnel.
• Let the engine reach operating temperature.
• Check for leaks at both hose ends.

Step 7: Final tighten and inspection

• Shut the engine off and let it cool again.
• Recheck the coolant level and top off if needed.
• Inspect the hose routing to make sure it is not rubbing or twisted.
