⚠️ Safety & Precautions

• Engine and coolant can be extremely hot. Work only with the engine fully cold.
• Coolant is toxic. Keep it away from kids, pets, and painted surfaces.
• Do not remove the radiator cap on a hot engine.
• Use jack stands if you need under-vehicle access. Never rely on a jack alone.
• If your Camry has an electric cooling fan that may cycle on, keep hands and tools clear when the battery is connected.
• Battery disconnect is not required for a simple hose replacement, but it can be done for extra safety if you will work near the fan or starter area.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Relieve coolant pressure

• Make sure the engine is cold.
• Slowly loosen the radiator cap to relieve any remaining pressure, then remove it.
• Open it slowly.

Step 2: Drain enough coolant

• Use the radiator drain plug or lower hose connection to drain coolant into a drain pan.
• Drain only enough coolant so the hose level drops below the hose ends.
• If using the drain plug, open it by hand or with a flat-blade screwdriver if needed.

Step 3: Gain access to the hose

• Remove the engine cover or intake ducting if it blocks access. Use a 10mm socket and 1/4-inch ratchet if fasteners are present.
• Move any clips or covers out of the way.
• Take photos before disconnecting.

Step 4: Remove the old hose

• Use hose clamp pliers or needle-nose pliers to slide the spring clamps away from both ends of the hose.
• Twist the hose gently by hand to break it loose.
• Pull the hose off the radiator neck and engine fitting.
• If it sticks, use a flat-blade screwdriver very carefully to help lift the hose edge. Do not gouge the fittings.

Step 5: Inspect the fittings

• Clean the radiator neck and engine pipe with shop towels.
• Check for corrosion, cracks, or pitting where the hose seals.
• Replace damaged clamps if they are weak, rusty, or deformed.

Step 6: Install the new hose

• Compare the new hose to the old one to confirm the shape and length match.
• Slide the clamps onto the hose first.
• Push the hose fully onto both fittings until it seats against the stop.
• Position the clamps directly over the hose beads.
• Feel for a full seat.

Step 7: Reinstall removed parts

• Put back any intake ducts, covers, or brackets you removed.
• Use the 10mm socket and 1/4-inch ratchet to reinstall fasteners.
• Tighten any removed 10mm fasteners to 8 N·m (71 in-lbs).

Step 8: Refill the cooling system

• Close the radiator drain plug if it was opened.
• Use a funnel to refill with Toyota Super Long Life Coolant.
• Fill slowly to reduce air pockets.
• Top off the overflow reservoir to the correct mark.

Step 9: Bleed air from the system

• Start the engine with the heater set to HOT and the fan on low.
• Let it idle and watch for bubbles in the radiator neck or funnel.
• Add coolant as the level drops.
• Once the thermostat opens and cabin heat is warm, install the radiator cap.

Step 10: Check for leaks

• Inspect both hose ends, the clamps, and the drain area for leaks.
• Shut the engine off and recheck the coolant level after it cools.
• Top off the reservoir if needed.

✅ After Repair

• Drive the vehicle until fully warm, then recheck for leaks.
• Confirm the temperature gauge stays normal.
• Recheck coolant level again the next morning when cold.
• If the coolant warning light comes on or the engine overheats, stop driving and inspect the system immediately.
