How to Properly Use a Car Jack
2 Answers
Correct method for using a car jack: 1. Before using the jack, park the car properly and place a safety warning triangle 50 to 150 meters behind the vehicle; 2. Turn off the engine to prevent the jack from slipping due to engine vibration; 3. Align the jack with the support point at the bottom of the car, which is the position marked by the car manufacturer (near the side skirt); 4. Connect the matching wrench and sleeve to the rear of the jack, and simply rotate it to control the height of the jack. The car jack is stored in the vehicle's toolbox and is used to lift the car body when changing a spare tire.
As someone who frequently deals with emergencies on the road, I’d like to share some tips on using a jack correctly. First, find a flat and solid surface—avoid muddy or sloped ground, as the jack may slip or sink. Next, locate the manufacturer-specified lifting points under the vehicle, usually notches or protrusions on the frame, and never place the jack on the oil pan or fragile components. Once the jack is positioned, slowly turn the wrench or handle to raise the vehicle, controlling the speed to prevent sudden shaking. As soon as the wheel is off the ground, immediately secure the support point with jack stands for safety—never rely solely on the jack, as failure could have serious consequences. When changing a tire or performing repairs afterward, I always double-check the jack’s stability and wear gloves to protect my hands. During routine car maintenance, also inspect the jack’s lubrication to prevent rust-induced jamming.
