It’s common for car enthusiasts and DIYers to talk about “Car Jacks” when discussing vehicle maintenance, but it’s crucial to understand the difference between car jacks and jack stands, especially when it comes to safety. Using the right equipment and understanding its limitations is paramount for anyone working on their vehicle at home.
The initial confusion often arises because “car jack” can be a general term, but in automotive contexts, it usually refers to the hydraulic jack that comes with your car for changing tires. However, relying solely on this type of jack for any maintenance work underneath your vehicle is extremely dangerous. These jacks are designed for emergency tire changes and are not meant to support a car’s weight for extended periods or while you are working underneath it.

For any work that requires you to be under your car, jack stands are indispensable safety equipment. Jack stands are sturdy, mechanical supports designed to hold the weight of your vehicle securely and safely. They work in conjunction with a car jack – you use the jack to lift the car to the desired height, then you position jack stands at designated support points and lower the car onto them. This creates a stable and safe working environment.

When choosing jack stands, capacity is a critical factor. It’s essential to know the weight of your vehicle and select jack stands that are rated to handle at least that weight, with a safety margin preferred. For instance, a large SUV might place significant weight on the jack stands, and exceeding their rated capacity is a serious safety hazard. Always consult your vehicle’s owner manual for its weight and recommended jacking points.
Beyond jack stands, car ramps offer another option for lifting your vehicle, particularly for tasks like oil changes. Ramps allow you to drive your car up onto an incline, providing increased ground clearance for easier access underneath. Modern ramps, like those made from durable plastic with a honeycomb structure, are often preferred over older steel ramps due to their lighter weight and resistance to slipping.

Regardless of whether you use jack stands or ramps, always prioritize safety. It’s a good practice to back up jack stands with additional supports, such as wheel chocks or even spare tires placed strategically. Before starting any work, ensure your vehicle is parked on a level, solid surface, and always engage the parking brake.
Even for experienced DIYers, getting under a car can be the most challenging part of the job. Planning ahead and having all necessary tools within reach minimizes movement and potential disruptions while working safely under your vehicle.
Performing routine maintenance like oil changes can be straightforward with the right tools and procedures. Using ramps or jack stands to elevate the car, allowing gravity to assist with draining old oil overnight, can simplify the process. It’s always recommended to consult your vehicle’s specifications for oil capacity and proper maintenance procedures.
In conclusion, while the term “car jacks” might be used loosely, understanding the distinction between emergency jacks and safety jack stands is vital for safe DIY car maintenance. Always prioritize safety by using jack stands when working under your vehicle, choosing the right equipment for the job, and implementing backup safety measures. Whether using jack stands or ramps, proper technique and respect for safety precautions are paramount for every car enthusiast and DIY mechanic.
