Yes, the 2003 Saturn Ion's battery, which is located in the trunk compartment, requires a vent tube. This tube helps to safely vent any gases that may be released during the battery's operation, preventing the buildup of potentially harmful gases in the enclosed trunk space. It's important to ensure that the vent tube is properly installed and functioning to maintain safety and battery performance.
why dose the new battery and cables not seem to hold a charge in my 2004 saturn ion ?
The battery is in the trunk, next to the spare tire. It's there to give better front to back weight distribution and longer life to the battery because it doesn't heat up with the engine.
in the trunk on the right side near the spare, if you need to jump start the car, there is a post in the front engine compartment that easily lets you connect your wires to it.
