ABSTRACT:
A production method of a water jacket spacer for use in a cylinder block with a water jacket formed around plural cylinder bores. The method comprises the fist step of integrally forming a tubular spacer body with a peripheral wall and a connecting bridge by way of synthetic resin molding so that corresponding regions of the peripheral wall are connected to each other via the connecting bridge, and the second step of cooling the tubular spacer body, with the connecting bridge fixed thereto, to prevent deformation of the tubular spacer body during the cooling process, and the third step of removing the connecting bridge from the tubular spacer body.
