  1. Raise and safely support the vehicle, as required.

When draining 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 coolant into a sealable container. Coolant may be reused unless it is contaminated or several years old.

  1. Drain the cooling system. If the freeze plug is located in the cylinder block, it will be necessary to remove the drain plug from the side of the block to make sure all coolant is drained.
  3. Drill a 1/2 in. (13mm) hole in the center of the plug. Remove the plug with a slide hammer or pry it out with a prybar.
