CAUTION When draining coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze, and quite likely to drink any is is left in an uncovered container or puddles on the ground. This will prove fatal in sufficient quantity. Therefore, drain coolant into a sealable container. Coolant should be reused Unless it is contaminated or several years old. The epa warns that prolonged contact with used engine oil may cause a number of skin disorders including cancer. You should make every effort to minimize your exposure to engine oil. Protective gloves should be worn when dealing with engine oil. Wash exposed skin immediately after contact with oil with soap and water, or waterless hand cleaner.
