Air bleeding system for an automotive engine cooling system instrument module
First Claim
1. In a system for analyzing cooling problems in a closed automotive engine cooling system, wherein a cooling instrument module is inserted in series with a flow path of the automotive cooling system, an improvement comprising in combination:
- a first fluid fitting being connected to a first internal point in the cooling instrument module;
a second fluid fitting being connected to a second internal point in the cooling instrument module; and
a coolant reservoir, said coolant reservoir having a first and a second fluid passage through a wall thereof, said first fluid passage being connectable through a first conduit to said first fluid fitting, said second fluid passage being connectable through a second conduit to said second fluid fitting.

Abstract
The invention comprises an improvement for an automotive engine cooling testing system wherein a coolant reservoir is connected to the instrument module by means of two quick disconnect fittings; each such fitting is provided with an internally located shut-off valve that is actuated to close when a disconnection is made. The improvement provides a convenient way to bleed air out of the cooling system prior to commencement of a testing routine, therefore providing a more accurate test result.

9. An improved method for removing air from an automotive cooling system and a testing apparatus comprising an instrument module, the instrument module being connected in series with the automotive engine cooling system, the improved method comprising the steps of:
-
attaching at least two ports in a coolant reservoir to at least two ports in the instrument module by means of at least two conduits; allowing air to escape into said coolant reservoir from at least one of said two ports in said instrument module through at least one of said at least two conduits by means of gravitational forces; and allowing a reservoir coolant to flow through another of said at least two conduits from said coolant reservoir bottle to another of said at least two ports in said instrument module by means of gravitational forces. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
