This paper used reverse engineering techniques in order to obtain of an existing physical model. A three-dimensional piston has been created with the help of SOLIDWORKS and it is imported to ANSYS environment for the coupled steady-state thermal structural analysis. The material used for piston is Die Cast Aluminium DCA 1 2 and 3. The objective of this paper focuses the light weight piston design through finite element analysis and to optimize the piston design using parametric optimization. The results obtained from coupled field analysis and parametric optimization concluded the modified design is within the permissible limit along the selected materials for DCA2 and shows the maximum von misses stresses 78.75MPa factor of safety n is 5.67 and yield
