The engine cooling module (CRFM) is one of main sources of noise and vibration for an idling automobile. Here, a V6 engine cooling module was taken as a studying object when it was idling and its air conditioner was working, the vibration problem of this CRFM and the related steering wheel was investigated with simulation and tests, the influence factors affecting the vibration of this CRFM were analyzed. The numerical model of the CRFM vibration was built with MATLAB, energy decoupling and Newmark-Beta methodology, taking chassis and cooling fan vibration into account. The optimization of the CRFM isolators was performed based on a hybrid genetic algorithm, the results were validated with simulation and tests.
