ABSTRACT:
A device for draining engine oil in a DIY manner including an oil drain screw bolt, a valve, an oil drain tube, a spring element, and a control cable. The screw bolt has a cylindrical rod portion having a drain hole at the center, and a head portion having an oil outlet at one side communicating with the drain hole. The outer end of the oil outlet forms a threaded section of a larger diameter. The head portion is provided with a through hole in a direction perpendicular to the oil outlet. The valve is provided with a rod at a front end for receiving a spring. A front end of the rod is connected to a pull strap. The valve is locked in the through hole of the screw bolt by a sunk-head screw. The oil drain tube has a rotary connecting portion at a front end for locking in the threaded section of the oil outlet. A control valve is provided at a rear end of the oil drain tube. The control cable forms a hook portion at a front end thereof and is passed through a small duct at one side of the oil drain tube. Engine oil may be drained using the device, without the need to remove the screw bolt from the engine.
