  1. Drain the cooling system.

When draining the coolant, keep in mind that cats and dogs are attracted by the ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

  1. Disconnect the upper, lower and overflow hoses at the radiator.
  3. On automatic transmission equipped cars, disconnect the transmission fluid (or "oil'') cooler lines at the radiator.
  5. Depending on the model, remove the two top mounting bolts and remove the radiator and shroud assembly, or remove the shroud mounting bolts and position the shroud out of the way, or remove the side mounting bolts. If the air conditioner condenser is attached to the radiator, remove the retaining bolts and position the condenser out of the way. Do not disconnect the refrigerant lines.
  7. Remove the radiator attaching bolts or top brackets and lift out the radiator.
  9. If a new radiator is to be installed, transfer the petcock (draincock) from the old radiator to the new one. On cars equipped with automatic transmissions, transfer the fluid cooler line fittings from the old radiator.
  11. Position the radiator and install, but do not tighten, the radiator support bolts. On cars equipped with automatic transmissions, connect the fluid cooler lines. Then, tighten the radiator support bolts or shroud and mounting bolts.
  13. Connect the radiator hoses. Close the radiator petcock. Fill and bleed the cooling system.
  15. Start the engine and bring it to operating temperature. Check for leaks.
  17. On cars equipped with automatic transmissions, check the cooler lines for leaks and interference. Check the transmission fluid level.
