Abstract
A fuel cooler and coolant filter assembly for the filtering of coolant and the cooling of a fuel flow for use in connection with a cylinder head of a vehicle engine includes three primary components which are assembled to one another in a stacked configuration and which in turn are assembled to the cylinder head. These three primary components include a fuel cooler core which is assembled directly to the cylinder head and which includes a fuel inlet, a fuel outlet, and a heat exchanger. The interior of the fuel cooler core is designed for the incoming fuel to flow and circulate across the exterior of the heat exchanger prior to exiting. The second primary component includes a filter head assembly with various inlets, outlets, and passageways. The filter head assembly is attached directly to the fuel cooler core so as to deliver coolant into the heat exchanger. The third component is a coolant filter which is connected to the filter head assembly and which filters the flow of coolant from the filter head assembly and then introduces the coolant back into the filter head assembly. A shut off valve is positioned in the filter head assembly so as to block the flow of coolant from the c…
