Your car's axles help you keep your wheels connected to the body of your car. The axles bear weight of the vehicle and must also be able to sustain the forces from braking, accelerating and turning. Over time these axles may need to be maintained and replaced.
Your car's battery is as important as the engine itself. The battery provides electricity to the starter as well as lights and other electronic components. Batteries will need testing and replacement several times over the life of your car.
Belts found in a car keep parts moving properly. Over time, these rubber belts sustain normal wear and your belts will need replacing at regular intervals. Belts should be replaced before they cause car troubles so they should be regularly inspected.
The radiator is the major component of your vehicle's cooling system. As you're driving, you should always monitor the temperature of your car via the dashboard indicator. Any cases of overheating should be checked.
A properly working heating system will help keep you comfortable in cold weather months. Driving with gloves or sitting on your hands isn't safe and fogged up windows are the worst. Keep your windows clear and your hands warm with a properly working heater.
