Regular water pump service is critical to preventing engine overheating. Impellers can dry out and lose elasticity during off-season storage, or wear with use — making annual replacement a best practice. Sierra's 18-3571 kit bundles all necessary housing components together, eliminating the need to source individual parts separately.
