<human>:  How do I winterize my car?
<bot>: To winterize your car, start by checking the coolant system. Make sure the coolant levels are topped off and that the coolant itself has enough antifreeze. Change the oil and replace the oil filter. Winter is often hard on batteries, so check the connections and make sure the battery is holding a charge. Inspect the tires and replace them if necessary. Make sure the windshield wiper fluid is topped off with antifreeze. Finally, check the hoses for any cracks or leaks.
