  • Patent number: 11807198
    Abstract: A machine for replacing used transmission or power steering fluid in a vehicle with new transmission or power steering fluid includes a frame having a housing. The machine includes a pair of service hoses that extend from the machine and connect to the vehicle for placing the machine in the fluid flow. New, used, and axillary fluid tanks are provided. A pump and a manifold are associated with two of the tanks. The pumps provide for the selective withdraw or insertion of fluid into or out of the tanks. A display on the housing presents an operator of the machine with various tasks or options the machine can perform. A processor controls activation of the pumps and other electrical components based on inputs received by the display. Scales are provided under one or more of the tanks for determining the amount of fluid going into and out of the tanks during the exchange process.

  • Patent number: 6978753
    Abstract: A device for and method of decarboning a combustion chamber and compression rings in an internal combustion engine. The device is a squid shaped container with a cylindrical body, a screw cap, and conduits depending from the body for transmitting cleaner to the combustion chambers on the engine. Once cleaner is transmitted to the combustion chambers, the engine is bumped to work the fluid into the compression rings using an automated system with a timer. When the engine is bumped, the device allows the cleaner to be vented to the device to avoid hydrolocking the engine. The device also contains the cleaner so that it is not splashed outside the engine.

  • Patent number: 6886664
    Abstract: Disclosed is an apparatus and process for exchanging an engine fluid for maintenance purposes. The fluid is accessed through the engines reservoir for that particular fluid. Used fluid is removed simultaneously with the introduction of new fluid. In order to maintain a constant level of fluid in the reservoir, and thus, prevent overflow or cavitation problems, a control module is presented that enables the user to control the rate of new fluid flow into the reservoir relative to the rate of used fluid and to activate and deactivate the new and used fluid pumps. During operation, the module is located in close proximity to the reservoir such that the user is able to observe the fluid level while relating the flows.

  • Publication number: 20040250370
    Abstract: Disclosed is a device and method for cleaning the air-intake system of an EGR-valve-equipped diesel engine. The EGR valve is removed and replaced with a vessel in which a pressure drop is created. The pressure drop creates sufficient vacuum so that cleaner may be administered into the air-intake duct of the vehicle. The vessel uses sizeable vanes to control the vacuum. The vanes also create turbulence which make the cleaner more effectively contacted with contaminants existing within the air intake system. An auger is also disclosed for cleaning out the inside surfaces of the air-intake duct so that contaminants are not allowed to crumble into the air intake system. Also disclosed is a cleaner which is particularly useful in cleaning diesel engines and may be used with the devices and methods described above.

  • Patent number: 6536486
    Abstract: A method of flushing the brake system of a vehicle is provided by administering new brake fluid to the master cylinder under pressure while at the same time suctioning with a clear wand old brake fluid from a particular bleeder valve on the vehicle with all the remaining valves closed. Once the particular valve has been adequately bled, new brake fluid will be seen coming out of the valve through the clear wand, and the valve should be closed. This procedure is repeated for each of the remaining valves one at a time until all of the bleeder valves on the vehicle have been bled. Ideally, the first valve selected should be the one furthest from the master cylinder and the last valve selected should be the one closest to the master cylinder.
