Simply slide the suction tube down your dipstick tube, pump the handle to create a vacuum inside the lightweight, 6.8 quart chamber, and in a matter of minutes the oil will be sucked out of the sump! Also use it to suck out heavy transmission fluid, differential fluid, gear oil, antifreeze, and power steering fluid or brake fluid. Remove water from a backed up sink or fish tank. The suction valve automatically shuts off when the 24" tall, 6 1/2" diameter chamber is full. The captured liquid dispenses easily for recycling. Includes three dipstick tubes and a brake bleeding tube with a bleeder valve adapter. May not fit all vehicles; call or email to confirm.
