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.
