ABSTRACT:
Fixturing and processes for automotive diagnostic and repair procedures are disclosed involving simultaneous pressurizing of the cylinders of a piston internal combustion engine for servicing the engine. The fixturing includes a manifold body having passages and a number of outlet ports pressurized by connection to a source of air pressure, each port being fitted with a pressure coupling for connection to one end of a pressure hose. Each pressure coupling includes a check valve which closes the associated outlet port if a pressure hose is not coupled thereto so that fewer hoses than the total number of outlet ports may be pressurized. Checks for leaking valves and piston rings are conducted by removal of one hose at a time after pressurization of all of the cylinders, while checks for head gasket leaks and valve servicing are conducted while a number of cylinders are simultaneously pressurized.
