An improved flushing system accessory that comprises a connector and a lubricating-fluid vessel. The connector has a threaded first intake port connected to a water supply hose, and a second intake port coupled to a non-vented bottle containing lubricating fluid. The connector further includes a threaded outlet port sized for connection to a marine engine flushing accessory. The connector has an internal chamber to draw fluid from which is divided by a partition wall into a first passageway and a second passageway. The intake and outlet ports are in fluid communication with the interior chamber. Lubricating fluid supplied by the lubricating-fluid vessel, and water supplied by a water supply hose, enter through a first and second intake port, respectively. They then pass through the connector outlet port and into an attached marine engine flushing accessory.

A method for charging coolant in a cooling system for a vehicle may include determining a vehicle-diagnostic apparatus connection that determines whether a diagnostic apparatus configured for charging coolant has been connected to a vehicle; starting a coolant charging mode for charging the coolant by the diagnostic apparatus; and determining whether a coolant charging mode release condition has been satisfied after starting the coolant charging mode.

The present disclosure relates to a turbocharged internal combustion engine which will flush dirt periodically from the heat exchange surfaces of the LT-charge air cooler by using water condensed on the heat exchange surfaces for the flushing.

An apparatus and a method are provided for an air box with an integrated air filter to communicate air flow from an exterior of the air filter to an air intake of an automobile engine. The air filter comprises a filter material that surrounds at least a portion of an interior cavity of the air filter. An end cap is affixed to a distal end of the filter material, and a wire support extends along at least a portion of the exterior surface of the filter material. The air box comprises a housing portion and a mount portion. The housing portion is configured to direct air drawn through the filter material into the interior cavity of the air filter and then into the air intake of the automobile engine. The mount portion is configured to support the air box and the air filter once installed within an automobile engine bay.

A vehicle coolant system includes a pipe configured to facilitate a flow of vehicle coolant through the pipe, a light source configured to transmit at least one wavelength of light through the vehicle coolant, and a signal detector configured to receive at least one wavelength of light transmitted through the vehicle coolant, and to generate a signal intensity value corresponding to a measured intensity of the at least one wavelength of light received at the signal detector. A controller is configured to receive the signal intensity value from the signal detector, identify a coolant contamination threshold value corresponding to the vehicle coolant, compare the signal intensity value received from the signal detector to the coolant contamination threshold value, and initiate a vehicle coolant remedial action according to a result of comparing the signal intensity value received from the signal detector to the coolant contamination threshold value.

An engine oil cooler backflush valve assembly is provided as a replacement cap to an engine oil cooler EGR coolant supply cover. The backflush valve assembly includes a main body through which a valve stem is inserted. The valve stem has a bushing threadedly attached thereto which moves the valve stem between first and second positions. A removable cap is provided to cover the backflush valve assembly during normal operation and to be removed during backflush operation. A removable lock can also be used to secure the cap and/or bushing to the main body of the assembly.
