While the present disclosure is subject to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and will herein be described in detail. The invention should be understood to not be limited to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present disclosure.
DETAILED DESCRIPTIONIn the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. It will be apparent, however, to one of ordinary skill in the art that the invention disclosed herein may be practiced without these specific details. In other instances, specific numeric references such as “first hose,” may be made. However, the specific numeric reference should not be interpreted as a literal sequential order but rather interpreted that the “first hose” is different than a “second hose.” Thus, the specific details set forth are merely exemplary. The specific details may be varied from and still be contemplated to be within the spirit and scope of the present disclosure. The term “coupled” is defined as meaning connected either directly to the component or indirectly to the component through another component. Further, as used herein, the terms “about,” “approximately,” or “substantially” for any numerical values or ranges indicate a suitable dimensional tolerance that allows the part or collection of components to function for its intended purpose as described herein.
In general, the present disclosure describes an apparatus and a method for a water neck for use with a water pump whereby a coolant may be circulated from a radiator to an LS engine. The water neck comprises a conduit which includes an interior opening configured to receive the coolant from a water hose extending from the radiator. The conduit is comprised of an elongate, cylindrical section having a smooth exterior surface and a circumferential edge. The cylindrical section and the circumferential edge are configured to receive the water hose extending from the radiator. A base is configured to be coupled with the water pump, such that the coolant is conveyed from the water pump through the conduit. The base is configured to be installed onto a coupling of the water pump. The base and the coupling comprise smooth surfaces sharing substantially the same size and shape suitable for establishing a fluid-tight seal. A supportive section interconnects the conduit and the base, and is configured to orient a longitudinal axis of the conduit relative to the base so as to direct the conduit and the water hose away from the LS engine and a belted pulley assembly of the LS engine.
The straight water neck 140 comprises a conduit 144 and a base 148 that are interconnected by way of a supportive section 152. In some embodiments, the conduit 144, the base 148, and the supportive section 152 may comprise sections of a single piece of material, such as billet aluminum, which is machined so as to produce the straight water neck 140 illustrated in
The conduit 144 generally is comprised of an elongate, cylindrical section 156 having a smooth exterior surface, an interior opening 160, and a circumferential edge 164. The cylindrical section 156 and the circumferential edge 164 are configured to receive a water hose extending from the radiator. The cylindrical section 156 generally has an outer diameter sized such that the conduit 144 may be slidably inserted into an interior opening of the water hose. It is contemplated that any of a wide variety of mechanical fasteners may be used to fasten the water hose onto the conduit 144 so as to form a fluid-tight seal between the straight water neck 140 and the water hose. Preferably, the circumferential edge 164 comprises at least one structure configured to cooperate with the water hose and the mechanical fastener so as to retain the fluid-tight seal between water hose and the conduit 144 during operation of the engine 104. For example, the circumferential edge 164 may comprise any of a variety of ridges, lips, or raised portions so as to optimally engage the water hose. It should be understood that the specific configuration of the conduit 144 depends upon the particular configuration of the water hose being utilized, and thus a wide variety of specific configurations may be incorporated into the conduit 144 without straying beyond the scope of the present disclosure.
As mentioned above, the supportive section 152 interconnects the conduit 144 with the base 148. The supportive section 152 serves as a structural foundation for the conduit 144, and orients a longitudinal axis 146 of the conduit 144 relative to a plane of the base 148 so as to direct the conduit 144, and thus the water hose, away from the LS engine 104 and the belted pulley assembly 112. In the embodiment illustrated in
As will be appreciated, the interior opening 160 extends through the conduit 144, the supportive section 152, and the base 148 such that coolant received into the base from the water pump is conveyed through the water neck 140 to the water hose. As such, the base 148 is configured to be installed onto the water pump 108 as illustrated in
As shown in
As will be appreciated, the straight water neck 140 may be installed onto the water pump 108 with the gasket disposed therebetween. In some embodiments, the gasket may be treated with any one of various gasket sealants so as to further prevent coolant from leaking out of the coupling between the straight water neck 140 and the water pump 108. During installation of the straight water neck 140, a thin layer of gasket sealant may be applied to the smooth surface of the base 148. The gasket may then be applied to the smooth surface of the base 148 such that the holes in the gasket are aligned with the first and second holes 168, 172. While the thin layer of gasket sealant holds the gasket fixed to the base 148, a thin layer of gasket sealant may be applied to the remaining exposed surface of the gasket. Further, in those embodiments wherein the base 148 includes the circumferential countersink, the thermostat valve may be positioned between the base 148 and the gasket. In other embodiments, the thermostat valve may be installed into the coupling 120. The straight water neck 140 with the gasket and sealant may then be pressed onto the smooth surface 124 of the water pump 108 such that the first and second holes 168, 172 are respectively aligned with the first and second threaded holes 128, 132. While holding the straight water neck 140 in position, the bolts 176 may be inserted into the first and second holes 168, 172 and then threadably engaged with the first and second threaded holes 128, 132. Installation of the straight water neck 140 may be completed by applying a manufacturer recommended degree of torque to each of the bolts 176.

In addition, where methods and steps described above indicate certain events occurring in certain order, those of ordinary skill in the art will recognize that the ordering of certain steps may be Modified and that such modifications are in accordance with the variations of the invention. Additionally, certain of the steps may be performed concurrently in a parallel process when possible, as well as performed sequentially as described above. To the extent there are variations of the invention, which are within the spirit of the disclosure or equivalent to the inventions found in the claims, it is the intent that this patent will cover those variations as well. Therefore, the present disclosure is to be understood as not limited by the specific embodiments described herein, but only by scope of the appended claims.
