Abstract: A combustion gas detection apparatus includes a transparent tube partially filled with a combustion gas sensing fluid and an inlet fitting for engagement with the radiator cap of an engine cooling system and an outlet fitting connected with a vacuum port of the engine.

Abstract: A manual trigger actuated automotive hose clamp release mechanism includes a flexible cable in a flexible tube. The cable and tube are attached respectively to opposed jaws designed to engage the end tabs of an automotive hose clamp and effect release of the hose clamp in response to movement of the cable relative to the tube. Mechanical advantage is gained by use of the manual trigger mechanism connected to the tube and cable in a manner enabling movement of the telescoping cable relative to the tube through which the cable extends thereby effecting movement of the jaws to release a hose clamp.

Abstract: A method for removal of a vehicle hub and rotor assembly from a steering knuckle that includes partially removing the bolts that attach the assembly to the knuckle followed by driving the bolts and the attached assembly from disengagement with the knuckle and subsequent total removal of the bolts thereby releasing the assembly. A special driving tool to effect the driving of the bolts, in particular, flange headed bolts, is depicted.

Abstract: A battery carrier comprises a handle having first and second ends threadably receiving, respectively, first and second threaded ends of first and second threaded rod members, the first threaded end and the second reverse threaded end being in opposed relation and defining an axis whereby rotation of a connecting member controls the spacing of handle members and attached battery gripping members; each of the gripping members includes an inwardly extending flange having an equal dimension transverse to the axis and extending equally in opposite directions from the axis of the handle by a distance at least two times greater than the width of first and second plate members.

Abstract: A hand hold connecting member having first and second ends threadably receiving respectively the first and second threaded and remove ends of the first and second threaded rod members, said first handle threaded end and said second handle reverse threaded end being in opposed relation whereby rotation of the connecting member controls the spacing of the handle members and attached grip members; each of said grip members including the inwardly extending flanges thereof having an equal dimension transverse to the axis and extending equally in opposite directions from the axis by a distance at least two times greater than the width of the first and second plate members whereby attachment of the carrier onto a rimmed battery enables positioning of the extending flanges underneath sections of a rim around the peripheral top of the battery.

Abstract: A circuit testing device includes a handle with a hollow interior, a conductive probe projecting from one end and a removable cap with a wire and clamp projecting from the opposite end A subassembly retained within a counterbore in the handle includes a polarity sensitive buzzer and light in a parallel circuit configuration whereby the device is useful for determining polarity, circuit continuity, and battery drain.

Abstract: A fan clutch wrench set includes multiple driving wrenches which are sized to fit in the restricted space between a fan and an engine block and to engage a fan clutch wrench retention nut inasmuch as the wrench is made from a thin plate of steel. A separate handle includes bifurcated legs which fit over the sides of the flat plate driving wrench and engage a driving surface so as to drive the driving wrench and impart a turning force against the nut.

Abstract: A mechanic's creeper includes a molded plastic platform with casters connected at the periphery of the platform. The platform includes molded indentations in its bottom layer which merge into the top layer in an array which enhances the structural integrity of the platform. The platform further includes distinct sections for support of head, shoulders, lumbar and buttocks of a user.

Abstract: A universal fan clutch wrench kit includes an adjustable holding wrench and an adjustable turning wrench, both of which are utilized in unison to remove a fan clutch assembly.

Abstract: A fan clutch wrench set includes multiple driving wrenches which are sized to fit in the restricted space between a fan and an engine block and to engage a fan clutch wrench retention nut in as much as the wrench is made from a thin plate of steel. A separate handle includes bifurcated legs which fit over the sides of the flat plate driving wrench and engage a driving surface so as to drive the driving wrench and impart a turning force against the nut.

Abstract: A universal Noid light for testing the output control voltage of an electronic fuel injector system includes a body with a lead wire wound on the body, a resistance light bulb maintained within the body and pins mounted on adjustable pin mounting arms.

Abstract: A bearing and circular raceway lubrication apparatus includes congruent and nesting male and female, polymeric material plates wherein the male plate includes a counterbore opening for receipt of a rod with a hollow shaft through which lubricant is directed into the region between nested plates when a bearing raceway is compressed between the plates. The female plate includes an integrally molded hub with a threaded throughbore for receipt of the hollow shaft.

Abstract: A combination ground and power source circuit tester device includes a cylindrical plug with a cone-shaped end that fits into a vehicle accessory receptacle. An attached body member engages the plug and retains first and second radially extending contacts that function to provide a connection with conductive studs that attach to leads to a circuit. A light bulb indicating that the circuitry is powered is retained in the body member and in a parallel circuit with the contacts.

Abstract: An improved tool extractor includes a head end and a broach end. The broad end includes a series of symmetrically arranged recesses and ribs generally defined about a longitudinal axis of the broach end.
