Assumption: This guide covers replacing one radiator hose on your 1500. The steps are similar for the upper or lower hose, but access may vary slightly.

🔧 Radiator Hose - Replacement

The radiator hose carries coolant between the engine and radiator. If it is soft, cracked, swollen, or leaking, replacing it now helps prevent overheating and engine damage.

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

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Drain enough coolant to lower the level

• Use a drain pan under the radiator.
• Open the radiator drain if equipped, or remove the reservoir cap only after the engine is fully cold.
• Drain enough coolant so the level falls below the hose you are replacing.
• Keep coolant off painted surfaces.

Step 2: Remove any intake ducting or covers in the way

• Use the 8mm socket or 10mm socket to remove any air duct fasteners or engine cover fasteners blocking access.
• Set the parts aside in order so they go back in the same place.

Step 3: Release the hose clamps

• Use hose clamp pliers to squeeze spring clamps, or use a flat-blade screwdriver if the truck has worm-gear clamps.
• Slide both clamps back on the hose.
• Twist the hose first to break it loose.

Step 4: Remove the old radiator hose

• Twist the hose gently at each end, then pull it off the radiator neck and engine fitting.
• If it is stuck, use a small pick carefully around the edge of the hose to break the seal.
• Do not pry hard on the plastic radiator tank or aluminum neck.

Step 5: Clean the hose connection points

• Use a clean shop towel to wipe both fittings until they are smooth and free of old rubber, rust, or crusty coolant residue.
• Inspect the fittings for cracks, deep pitting, or broken hose lips.

Step 6: Install the new hose

• Compare the new hose to the old one and make sure the bends match.
• Push the hose fully onto both fittings until it seats against the stop.
• Move the clamps into the same general position as the originals, just behind the bead on each fitting.
• If using worm-gear clamps, snug them with a flat-blade screwdriver or 8mm socket if the clamp uses a hex head.
• Torque to snug only; do not overtighten plastic fittings.

Step 7: Reinstall removed parts

• Reinstall any air ducting or covers using the 8mm socket or 10mm socket.
• Make sure nothing is rubbing the hose or touching the fan.

Step 8: Refill and bleed the cooling system

• Use a funnel to refill with the correct coolant mix.
• Fill the reservoir to the proper mark.
• Start the engine and let it idle with the heater set to HOT.
• Watch the coolant level and top off as air leaves the system.
• Replace the cap once the level stabilizes and no more air bubbles appear.
• Do not rev a cold engine.

✅ After Repair

• Check for leaks at both hose ends while the engine is idling.
• Let the engine reach operating temperature and verify steady heater output.
• Shut the engine off, let it cool, then recheck the coolant level.
• Inspect the hose again after a short test drive.
