ABSTRACT Water pump was driven by crankshaft via belt is the important part in engine coolant system.

Whose efficiency is significantly affected power output and fuel economy of engine .This paper is to show the coupling analysis by fluid dynamics (STAR_CCM+) and Stress analysis (Abaqus). Focusing on improve analysis on a production water pump impeller made by sheet metal which has a better strength, but may cause cavitation due to flat impeller and low efficiency design .

Using the plastic material and a backward-swept type in the impeller design can improve efficiency and fuel economy. And also a light weight and low cost design can be attained.

Initial calculation is using STAR-CCM+ to calculate the water pump flow field, and mapping the pressure boundary from velocity field to impeller as an initial stress condition in mapping surface in Abaqus. By doing the file-based coupling analysis, the stress condition from Abaqus can be useful information in pump design. Keywords: engine water pump, impeller, pressure boundary, coupling, STAR-CCM+,
