To safely and effectively position a jack under a car, locate the manufacturer’s recommended jacking points, usually indicated in the vehicle’s owner’s manual. These points are designed to support the vehicle’s weight without causing damage. Avoid using any other parts of the car, as this could lead to serious damage or injury.

How to Safely Position a Jack Under a Car

Positioning a jack under a car correctly is crucial for both your safety and the integrity of your vehicle. Whether you’re changing a tire or performing maintenance, following the right steps ensures that the car is stable and secure throughout the process.

Step-by-Step Guide to Positioning a Jack

1. Find a Level Surface: Ensure the car is parked on a flat, stable surface. This reduces the risk of the car slipping off the jack.

2. Engage the Parking Brake: Always engage the parking brake to prevent any movement while the car is lifted.

3. Locate the Jacking Points: Refer to your vehicle’s owner’s manual to find the designated jacking points. These are typically reinforced areas designed to bear the car’s weight.

4. Position Wheel Chocks: Place wheel chocks on the opposite end of the car you are lifting. For example, if you’re lifting the front, chock the rear wheels.

5. Align the Jack: Place the jack under the jacking point. Ensure it is perpendicular to the vehicle to distribute weight evenly.

6. Lift the Car: Slowly raise the jack until it makes contact with the jacking point. Continue lifting until the car is at the desired height.

7. Secure with Jack Stands: Once the car is lifted, place jack stands under the car for added safety. Lower the vehicle slightly onto the stands for stability.

Why It’s Important to Use the Correct Jack

• Efficiency: Makes the process of lifting and working on your car quicker and easier.

Practical Example: Changing a Tire

Imagine you have a flat tire on the side of the road. Here’s how you would position the jack:

1. Locate the Jacking Point: Check the owner’s manual or look for notches or reinforced areas under the car.

2. Position the Jack: Place it directly under the jacking point and ensure it’s stable.

3. Lift the Car: Turn the jack handle or crank until the tire is off the ground.

4. Secure with Jack Stands: Place them under the vehicle for added security.
