Abstract: A coolant valve mounting arrangement is provided for a vibrating environment with significant temperature fluctuations. The mounting arrangement includes a fastener, a housing, a compression limiter and a mounting base. The compression limiter is arranged to minimize the housing thickness in order to reduce subsequent thermal expansion effects, while maintaining packaging, stiffness and strength requirements. A spring washer can be implemented to ensure that an adequate force is applied to the housing to maintain the integrity of a leak-free interface with the mounting base.
