The essential car parts you should pack for a road trip are varied depending on the length of the journey. Typically, a driver should bring an extra water pump, gasket, and wiper fluid along for the ride. Additionally, drivers should bring additional warm clothing and an ice scraper in case of a breakdown. In case of a flat tire, they should pack a spare tire iron and a jack for the trip. Depending on the type of vehicle they have, chains are a good idea too. And a jumper cable is always handy car part to have. These are inexpensive and will come in handy if you ever have a dead battery. These are not just for emergencies but also useful for everyday driving.
