🔧 Camry - Radiator Hose Replacement

You’ll be replacing the radiator hoses that carry coolant between the engine and the radiator. This stops leaks and helps your Camry avoid overheating. We’ll cover both the upper and lower hoses.

Difficulty Level: Beginner-Intermediate | Estimated Time: 1.5–3 hours

⚠️ Safety & Precautions

• 🔹 Never open the radiator cap or hoses on a hot engine; hot coolant can spray and cause severe burns.
• 🔹 Let the engine cool completely (at least 1–2 hours after driving).
• 🔹 Support the front of your Camry with jack stands; never rely on a floor jack alone.
• 🔹 Coolant is poisonous to people and animals; avoid skin contact and clean any spills.
• 🔹 Disconnecting the battery is not required for this job.

📋 Before You Begin

• Park your Camry on level ground, engage the parking brake, and place wheel chocks behind the rear wheels.
• Let the engine cool completely; the upper radiator hose should feel cool to the touch.
• Set the heater inside the car to HOT and fan to LOW before you start bleeding coolant later.
• Locate the radiator cap (front of engine bay, on radiator) and the coolant overflow reservoir (plastic tank near radiator).
• Have your drain pan and rags ready under the front bumper before loosening anything.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise and support the front of the car

• Use the floor jack on the front center jacking point (under the subframe, behind the radiator support) to lift the front of your Camry.
• Place jack stands under the pinch welds on both sides and slowly lower the car onto them.
• Give the car a small push to be sure it sits solidly on the stands.

Step 2: Remove the lower engine splash shield

• Position the drain pan under the radiator area.
• Use a 10mm socket and 1/4" ratchet to remove the bolts holding the plastic splash shield under the radiator.
• Use the plastic trim clip remover to gently pop out any plastic clips.
• Lower the shield and set it aside. Reinstall bolts later and torque to 7.5 Nm (66 in-lbs).

Step 3: Drain the coolant

• Place the drain pan directly under the radiator drain plug (bottom of radiator, usually on the passenger side).
• Slowly loosen the radiator cap by hand to relieve any leftover pressure, then remove it.
• Use your hand or a small flathead screwdriver to open the plastic radiator drain cock (turn counterclockwise).
• Let the coolant drain until the flow slows to a drip.
• Close the drain cock by hand and then snug it gently; do not overtighten: Torque to 1.5 Nm (13 in-lbs).
• Plastic drain plugs crack easily; be gentle.

Step 4: Locate and inspect both radiator hoses

• The upper radiator hose runs from the top of the radiator to the top of the engine (thermostat housing area).
• The lower radiator hose runs from the bottom of the radiator to the lower/front side of the engine.
• Note how each clamp is positioned and where the hose sits on each fitting; you’ll want to match this with the new hoses.

Step 5: Remove the upper radiator hose clamps

• Use hose clamp pliers to squeeze the spring clamp on the radiator side of the upper hose.
• Slide the clamp back along the hose, several centimeters away from the radiator neck.
• Repeat on the engine side of the upper hose.
• If your Camry has screw-type clamps, use a flathead screwdriver or 8mm socket (if needed) to loosen them instead.

Step 6: Remove the upper radiator hose

• Gently twist the hose near the radiator using your hand to break it free. If it is stuck, carefully slide the hose pick tool under the hose edge to break the seal.
• Pull the hose off the radiator neck and aim the open end down into the drain pan to catch any leftover coolant.
• Repeat this at the engine side and remove the hose completely.
• Do not pry hard on plastic radiator necks.

Step 7: Remove the lower radiator hose clamps

• Move your drain pan under the lower radiator hose connection at the radiator.
• Use hose clamp pliers to compress the spring clamp on the radiator side and slide it back along the hose.
• Repeat on the engine side of the lower hose, using the work light to see clearly.
• Some coolant will still come out when you remove this hose; be ready with rags.

Step 8: Remove the lower radiator hose

• Twist the lower hose gently at the radiator end, then pull it off and let coolant drain into the drain pan.
• Repeat at the engine connection and remove the hose completely.
• If the hose is stubborn, use the hose pick tool carefully between hose and fitting, working around the circumference.

Step 9: Clean the hose connection surfaces

• Use rags to wipe the radiator necks and engine fittings where the hoses attach.
• Remove any loose rubber, corrosion, or dried coolant.
• Clean surfaces help prevent future leaks.

Step 10: Install the new upper radiator hose

• Compare the new upper hose to the old one to confirm shape and length match.
• Slide two clamps onto the new hose (one for each end).
• Push one end of the hose fully onto the radiator neck until it stops against the raised bead (ridge).
• Use hose clamp pliers to compress the clamp and position it just behind the bead.
• Repeat for the engine end of the hose, making sure there are no twists or kinks.
• Spring clamps do not need a torque spec—they self-adjust by design.

Step 11: Install the new lower radiator hose

• Compare the new lower hose with the old one for shape and orientation.
• Slide two clamps onto the new hose.
• Install the hose onto the engine-side fitting first, pushing it all the way to the bead.
• Use hose clamp pliers to move the clamp behind the bead.
• Then install the radiator-side of the hose, fully seating it and positioning the clamp behind the bead.
• Ensure the hose clears fans and belts and does not rub on anything.

Step 12: Double-check all clamps and fittings

• Use the work light and visually inspect each hose end.
• Confirm each clamp is centered over the fitting and just behind the raised bead.
• Make sure the radiator drain plug is fully closed: Torque to 1.5 Nm (13 in-lbs).

Step 13: Reinstall the lower splash shield

• Lift the splash shield back into place under the radiator.
• Install all plastic clips by hand.
• Use a 10mm socket and 1/4" ratchet to reinstall the bolts and torque to 7.5 Nm (66 in-lbs).

Step 14: Refill the cooling system

• Make sure the radiator drain is closed and the drain pan is moved aside.
• Place the funnel into the radiator neck.
• Slowly pour Toyota Super Long Life coolant into the radiator until it is full.
• Fill the overflow reservoir to the “FULL” or “MAX” line.

Step 15: Bleed air from the system

• With the radiator cap still off, start the engine and let it idle.
• Set the cabin heater to HOT and fan to LOW.
• Watch the coolant level in the radiator; as the engine warms up, air bubbles will come out and the level will drop.
• Add more coolant using the funnel whenever the level drops.
• Gently squeeze the upper radiator hose by hand a few times to help push air out.
• Once the engine is at normal operating temperature and bubbles stop, top off the radiator and install the cap.

Step 16: Final checks for leaks

• With the engine still running and the cap installed, look around all hose connections using the work light.
• Check for any drips or wet spots at the upper and lower hose ends and around the radiator drain plug.
• Shut off the engine and let it cool completely, then recheck the coolant level in the overflow tank and top off if needed.

Step 17: Lower the car

• Use the floor jack to lift the front slightly off the jack stands.
• Remove the jack stands and slowly lower your Camry to the ground.

✅ After Repair

• 🔹 Take a short test drive (10–15 minutes) while watching the temperature gauge; it should stay in the normal range.
• 🔹 After the engine cools fully, recheck the coolant level in the overflow reservoir and top off to the “FULL” line if needed.
• 🔹 Inspect under the front of the car and around the hose connections for any new leaks.
• 🔹 Over the next few days, check the coolant level again and monitor for any sweet smell or coolant spots under the car.
