An apparatus which enables a person to comfortable work on the engine of a vehicle includes base, spine, post, knee pad, and chest pad components. The spine component is pivotally connected to the base component. A brace prevents the pivoting movement but is removably connected between the spine and the base to allow pivoting when desired. The spine component carries the tube component at a selected height, and the tube component carries the knee pad component at a selected position. The tube component carries the chest pad component.

A viscous clutch head may be replaced by selecting a viscous clutch head and a mount adapter. The viscous clutch head and the mount adapter may be selected from a group of universal modular fan drives and from a group of mount adapters. The mount adapter of a threaded type or a flange and bolt type may be selected. Depending on the viscous clutch head to be replaced, a fan adapter and/or a pilot adapter may also be selected from a group of fan adapters and from a group of pilot adapters. Accordingly, a range of models of viscous fan clutch systems may be replaced by using a limited number of parts. These parts may be stored on a tool cart. As different models of viscous fan clutch systems may be replaced using a limited number of parts, the in-stock inventory of replacement parts may be reduced.

A dual-purpose mechanics creeper includes: a flat board, a first swing arm and a second swing arm pivotally attached to a bottom surface of the flat board. Each swing arm includes a plurality of rollers. When each swing arm is at the first position, it is adjacent to the bottom surface of the flat board. When the swing arm is at the second position, it is perpendicular to the flat board. When the second swing arm is at the second position, it is attached to the first swing arm, such that the second swing arm is obliquely supported between the flat board and the first swing arm.

A creeper for accessing cabinets includes a first end and a second end. The creeper includes a base support structure having a top surface, a bottom surface, and a plurality of side walls extending between the top surface and the bottom surface. The base support structure also includes a cabinet entry first end that is shaped and dimensioned for positioning within a cabinet and an exposed second end that is shaped and dimensioned to sit outside of the cabinet when cabinet entry first end of the creeper is positioned within the cabinet for use. A downwardly extending leg assembly is secured along the bottom surface of the base support structure. The cabinet creeper may be used for accessing a cabinet or as a seat with the user sitting directly upon the downwardly extending leg assembly.

A height adjustable plumber's support includes an elongated board having top and bottom major surfaces that extend from a proximal end to a distal end of the elongated board, a cushioned pad covering a central region of the top major surface, a head pad covering the top major surface adjacent the distal end of the elongated board, a foot pad covering the top major surface adjacent the proximal end of the elongated board, and a pair of flexible handles secured to opposite lateral sides of the elongated board. The height adjustable plumber's support includes a foldable support leg secured to the proximal end of the elongated board. The foldable support leg has a vertical section and a horizontally extending section. The foldable support leg is height adjustable for adjusting the height of the proximal end of the elongated board over a floor surface, such as when the distal end of the elongated board is inserted into a cabinet having an elevated base.

A fluid sample display for displaying actual vehicle fluid samples alongside comparisons of exemplary fluids has a tray with dimples to receive the fluid samples. The dimples are coverable by a movable cover. The tray can have an indicia panel for removably receiving indicia indicative of a vehicle and/or vehicle owner.
