Water Pump Adaptor for GM LS Engine Port Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The industry faces a need to adapt conventional electrical and mechanical water pumps to engine blocks with rectangular coolant entry ports and circular coolant exit ports, such as the GM LS engine, due to the high cost and bulkiness of Chevrolet's LS engine specific water pumps.
Innovation Solution
A water pump adaptor kit is provided, comprising adaptor elements with proximal, distal, and longitudinal surfaces, featuring rectangular and circular openings to match the engine ports, allowing standard water pumps to be attached and ensuring coolant flow compatibility, along with pump adaptor plates and fittings for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a Chevrolet LS engine specific water pump is used, then the water pump is designed to be specific to the LS engine block, but the water pump becomes expensive and bulky
Solution Approach 1:
The patent introduces an adaptor element as an intermediary component between the conventional water pump and the LS engine block. This adaptor includes a first portion that interfaces with the conventional pump and a second portion that interfaces with the engine block, allowing the pump to be adapted without requiring a complete redesign of the pump itself, thus reducing cost and complexity while maintaining compatibility
Solution Approach 2:
The water pump system is segmented into three distinct components: the conventional water pump, the adaptor element, and the LS engine block. This segmentation allows each component to maintain its original design integrity while working together as a functional assembly, avoiding the need to redesign the entire pump system
2Device complexity
If a conventional water pump is adapted to LS engine, then cost and compactness are improved, but the adaptor must accommodate different port configurations
Solution Approach 1:
The adaptor element incorporates locally adapted features including a first opening configured to receive a conventional water pump and a second opening configured to receive an adapter plate, with specific geometric characteristics tailored to match the LS engine block's rectangular and circular port configurations. This localized adaptation allows the rest of the adaptor to maintain a simple, compact structure
Solution Approach 2:
The adaptor element is designed with universal applicability to accommodate different port configurations through its multi-functional opening structures. The first opening can receive various conventional pump types while the second opening interfaces with the LS engine block's unique rectangular and circular ports, making the adaptor versatile across different configurations

Function Achieved in This Case
The kit enables the adaptation of standard water pumps to GM LS engines, offering a cost-effective and compact solution that maintains coolant flow efficiency, allowing for the use of a wide variety of pumps with the LS engine block, reducing costs and maintaining performance.
Implementation Method 1
a first channel through the water pump adaptor, the first channel connecting the additional opening on the longitudinal surface to the first circular opening. The adaptor may further comprise a second channel through the water pump adaptor, the second channel connecting the rectangular opening to the second circular opening
