First debuted in 2005, the Tucson represents Hyundai's first steps into the small SUV car market. Combining body style elements from sport utility vehicles with a more economic engine, helped the Tucson launch as a successful car brand. The engine in these vehicles is reliable and generally only requires basic maintenance, such as changing the battery periodically.
Pull the hood release lever, located just inside the driver's door, near the floor, to open the bonnet of the Hyundai Tucson. Use a ratchet equipped with a metric socket set to remove the engine cover.
Locate the battery and spray a small quantity of terminal corrosion spray on the negative node of the battery. Using the wire brush, scrub off any residue of corrosion on the nodes. Use a 19mm box-end wrench to loosen the bolt on the connection to the negative node. When the terminal is loose enough, wiggle the negative battery terminal out.
Remove the positive battery cable using the same method that was used to remove the negative cable. Use a wrench to loosen the connections on the cable, and clean any corrosion from the surface.
Remove the old battery and set it to the side. Lift the battery from its tray and completely remove it from the engine section. Insert a new battery into the exact place that the old battery was removed from. The Hyundai Tucson uses a 9 volt 24-24F car battery. Clean the battery terminals using a wire brush.
Align the terminals to the adjacent nodes of the battery. Connect the positive node to the positive battery terminal and the negative node to the negative terminal. Use a 19mm box wrench to secure the connectors to the terminal posts. Spray the terminals with anti-corrosion spray and then place the engine cover securely above the battery.
Wear goggles and gloves, especially when handling the battery and sprays. Take the old battery back to the auto parts store for proper recycling.
Make certain you are using the proper battery size. Using a 12 volt car battery can damage the Hyundai Tucson.
