🔧 Camry - Radiator Hose Replacement

On your Camry, the radiator hoses carry hot engine coolant between the engine and the radiator. Replacing a cracked, swollen, or leaking hose prevents overheating and coolant loss.

Difficulty Level: Intermediate | Estimated Time: 1.0-2.0 hours

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the lower engine cover (if equipped)

• Lift the front using a floor jack (rated 2-ton minimum) and support it with jack stands (rated 2-ton minimum).
• Remove the under cover fasteners using a 10mm socket, ratchet (3/8" drive), and trim clip remover.

Step 2: Drain enough coolant to get below the hoses

• Place a drain pan (at least 10-quart) under the radiator drain.
• Slowly loosen the coolant fill cap using a shop rag (only if stone-cold) to release any residual pressure.
• Open the radiator drain cock (small plastic valve) by hand or with a flat-blade screwdriver (gentle—plastic).
• Drain about 1-2 gallons, then close the drain cock snugly by hand. Do not overtighten plastic.

Step 3: Replace the upper radiator hose (top hose)

• Locate the upper hose between the radiator top outlet and the engine.
• Move the clamp back:
  • Use hose clamp pliers (a tool that squeezes spring clamps evenly) or slip-joint pliers to compress the clamp and slide it back on the hose.
• Break the hose free:
  • Twist the hose gently by hand.
  • If it’s stuck, carefully work around the nipple with a pick tool (small) to break the seal. Don’t gouge the plastic radiator neck.
• Remove the hose and catch any remaining coolant using the drain pan (at least 10-quart).
• Install the new hose:
  • Push it fully onto both fittings until it bottoms out.
  • Reposition clamps using hose clamp pliers so each clamp sits behind the raised “bead” on the fitting.

Step 4: Replace the lower radiator hose (bottom hose)

• Locate the lower hose at the radiator bottom outlet and engine-side connection.
• Move both clamps back using hose clamp pliers or slip-joint pliers.
• Remove the hose:
  • Twist and pull by hand.
  • Use the pick tool (small) carefully if it’s stuck.
• Install the new lower hose and position clamps correctly using hose clamp pliers.

Step 5: Refill coolant

• Lower the car from the jack stands (rated 2-ton minimum) using the floor jack (rated 2-ton minimum) (car should be level for best fill).
• Refill with Toyota Super Long Life Coolant (pink, premixed 50/50) using a funnel or spill-free coolant funnel kit (specialty).
• Fill to the proper level in the reservoir/neck (depending on your fill point).

Step 6: Bleed air from the cooling system

• Start the car (READY mode) and set heat to MAX HOT and fan on medium.
• Let it warm up while watching the coolant level; add coolant as the level drops using the spill-free coolant funnel kit (specialty) or funnel.
• Gently squeeze the upper hose by hand (with nitrile gloves) to help move trapped air. Keep hands away from fans.
• When you get steady cabin heat and no more bubbles, install the cap.
• Shut down and let it fully cool, then recheck and top off the reservoir.

Step 7: Reinstall the under cover

• Reinstall the lower engine cover using the 10mm socket, ratchet (3/8" drive), and trim clip remover.

✅ After Repair

• Check for leaks with the engine warm: look at both hose ends and the radiator drain cock.
• Verify the heater blows hot and the temperature stays normal on the dash.
• After 1-2 drives (and a full cool-down), recheck coolant level and inspect clamp positions.
• If you see overheating, gurgling, or no heat, stop and re-bleed (air is still trapped).
