      Remove the fan mounting bolts, then remove the fan, along with the motor. Pull the radiator assembly out of the engine compartment and transfer any connections to the new radiator.

Tips & Warnings

  • You can reuse engine coolant, so, be environmentally responsible. If you choose not to reuse it, take it to a garage or hazardous waste facility where it can be disposed of properly.

  • Wear protective clothing, gloves and eyewear when replacing the radiator in your Toyota Corolla. Never open the radiator cap if the temperature of the engine coolant is 100 degrees or more, as serious burns can occur.

  • Be sure to keep engine coolant in a sealed container out of the reach of children and pets, and if any is spilled, clean it up immediately. Remember that cats and dogs are attracted to antifreeze, which can be fatal if ingested.
