    CAUTION
    When draining the coolant, keep in mind that cats and dogs are attracted by the ethelyne 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.
