When draining the coolant, keep in mind that cats and dogs are attracted by 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. Remove the expansion tank and hose, and drain the coolant. Remove the upper radiator hose. On cars with automatic transmissions, disconnect the transmission oil cooler lines at the radiator. Plug the lines immediately. Catch the spillage from the radiator in a separate pan.
  3. On later cars equipped with electric fans, carefully disconnect the wiring to the temperature sensor at the bottom of the radiator. Remove the retaining bolts for the radiator and fan shroud and lift out the radiator.

To install:
  1. Place the radiator and fan shroud in position and install the retaining bolts. Note that the placement of the radiator is important to its proper operation. The radiator must lie flush with the front bodywork, otherwise some air will go around the radiator instead of through it. Either adjust the position of the front panel or use plastic foam to seal the gaps between the radiator and the front panel.
  3. On automatic transmission cars, connect the oil cooler lines.
  5. Install the lower and upper radiator hoses.
  7. Install the expansion tank with its hose. Make sure that the overflow hose is clear of the fan and is free of any sharp bends.
  9. Fill the cooling system with a 50 percent antifreeze, 50 percent water solution. Replace the caps.
  11. Start the engine and check for leaks. After the engine has reached operating temperature, make sure the coolant level in the expansion tank is between the maximum and minimum marks. Check and top up the automatic transmission fluid level.
