Difficulty: Advanced · About 150 min · Toyota Camry

Replace the radiator on a 1997–2001 Toyota Camry by removing the cooling fans and hoses, transferring the temperature sensor and mounts, then refilling and bleeding the cooling system.

Steps

1. Disconnect the fans and temperature sensor

   With the engine cold, disconnect the fan connectors and release their wiring retainers. Remove the upper fan fasteners and lift both fan assemblies out, then unplug the coolant temperature sensor harness from the radiator.

2. Drain coolant and disconnect hoses

   Remove the radiator cap only when the system is cold. Raise and support the vehicle, remove the lower shield, drain coolant into a pan, and disconnect the lower radiator hose.

3. Disconnect cooler and radiator lines

   Mark the transmission cooler line positions before disconnecting them and catch any escaping fluid in a pan. Cap the open lines to prevent contamination, then disconnect the expansion and upper radiator hoses.

4. Remove the old radiator

   Remove the upper support bolts and lift the radiator straight out without damaging the condenser. Transfer the rubber mounts and temperature sensor, checking its O-ring and replacing it if damaged.

5. Install the replacement radiator

   Lower the new radiator into its mounts and secure the upper support. Reconnect the expansion, upper, lower, and cooler lines, then reinstall the lower shield and both fan assemblies.

6. Refill and bleed the cooling system

   Reconnect the sensor and fan wiring, then fill with the specified coolant mixture. Bleed the system using the vehicle's procedure while monitoring temperature and cabin heat, top off as needed, and inspect for leaks after a full cool down.

Check your vehicle’s repair manual for exact specifications and fit.
