Disclosed herein is an engine cooling system comprising a first wall in an engine block defining a coolant jacket including an upstream coolant jacket portion, a downstream coolant jacket portion, and a passage portion extending therebetween and including therein a valve seat, a second wall in the engine block defining a void opening into the exterior surface of the block and communicating with the coolant jacket in general alignment with the passage portion, a third wall in the engine block defining a recess opening into the exterior surface of the block and communicating with the void, a valve member having a flange with opposed first and second surfaces, which first surface engages the seat, a spring having a first end engaging the second flange surface and having a second end, a plug located in the void and having a surface engaging the second spring end, and an outer surface, and, a retainer located in the recess and engaging the outer plug surface to releasably retain the retainer in the recess and to releasably retain the valve member against movement away from the seat.
An engine cooling system comprising an engine block including an exterior surface, first wall means in said engine block defining a coolant jacket including an upstream coolant jacket portion, a downstream coolant jacket portion, and a passage portion extending between said upstream portion and said downstream portion and including therein a valve seat, second wall means in said engine block defining a void opening into said exterior surface of said block and communicating with said coolant jacket in general alignment with said passage portion, third wall means in said engine block defining a recess opening into said exterior surface of said block and communicating with said void, a valve member engaging said seat, a spring having a first end engaging said valve member and having a second end, a plug located in said void, and having a surface engaging said second spring end, and an outer surface, and a non-deformable retainer located in said recess and engaging said outer plug surface to releasably retain said retainer in said recess and to releasably retain said valve member against movement away from said seat.
An engine cooling system comprising an engine block including an exterior surface, first wall means in said engine block defining a coolant jacket including an upstream coolant jacket portion, a downstream coolant jacket portion, and a passage portion extending between said upstream portion and said downstream portion and including therein a valve seat, second wall means in said engine block defining a void opening into said exterior surface of said block and communicating with said coolant jacket in general alignment with said passage portion, third wall means in said engine block defining a recess opening into said exterior surface of said block and communicating with said void, said recess being generally of U shape and including a bite portion which is aligned with said void and which is of greater dimensions than said void, a valve member engaging said seat, a spring having a first end engaging said valve member and having a second end, a plug located in said void, and having a surface engaging said second spring end, and an outer surface, and a retainer located in said recess and engaging said outer plug surface to releasably retain said retainer in said recess and to releasably retain said valve against movement away from said seat.
An engine cooling system comprising an engine block including an exterior surface, first wall means in said engine block defining a coolant jacket including an upstream coolant jacket portion, a downstream coolant jacket portion, and a passage portion extending between said upstream portion and said downstream portion and including therein a valve seat, second wall means in said engine block defining a void opening into said exterior surface of said block and communicating with said coolant jacket in general alignment with said passage portion, third wall means in said engine block defining a recess opening into said exterior surface of said block in spaced relation to the opening of said void into said exterior surface of said block and communicating with said void, a valve member engaging said seat, a spring having a first end engaging said valve member and having a second end, a plug located in said void, and having a surface engaging said second spring end, and an outer surface, and a retainer located in said recess and engaging said outer plug surface to releasably retain said retainer in said recess and to releasably retain said valve member against movement away from said seat.
