Never use the tire changing jack (the little jack supplied with the car) for anything other than changing a flat out on the road. These jacks are simply not safe enough for any type of vehicle service except tire changing!
The service operations in this guide often require that one end or the other, or both, of the car be raised and safely supported. For this reason a hydraulic floor jack of at least 1 1 / 2 ton capacity is as necessary as a spark plug socket to you, the do-it-yourself owner/mechanic. The cost of these jacks (invest in a good quality unit) is actually quite reasonable considering how they pay for themselves again and again over the years.
Along with a hydraulic floor jack should be at least two sturdy jackstands. These are a necessity if you intend to work underneath the car. Never work under the car when it is only supported by a jack!
Drive-on ramps are an alternative method of raising the front end of the car. They are commercially available or can be fabricated from heavy lumber or steel. Be sure to always block the wheels when using ramps.
