An isolator for damping heat and vibrations between a heat shield and heat source is provided. The isolator includes a housing and a washer. The housing surrounds a center opening and extends axially from a first end portion to a second end portion and includes an intermediate portion therebetween. The housing has a serpentine shape. The first end portion and the intermediate portion of the housing clamp a washer therebetween, and the second end portion and the intermediate portion of the housing clamp the heat shield therebetween. The washer includes a plurality of through openings between an outer periphery and the center opening for enhancing vibration dampening and minimizing heat transfer from the heat source to the heat shield. The isolator optionally includes a collar member disposed along the center opening of the washer to facilitate mounting of the isolator to the heat source.
