Belt Guard

Courtesy of VOLVO CARS CORPORATION

Engines B4204T9/T10/T12/T13/T15 have a belt guard to protect the timing belt from external influences such as stones, water etc. The guard also provides some protection against an incorrectly installed or defective Accessory Drive Belt where on other engine options this can cause the Accessory Drive Belt to end up in the timing gear resulting in engine failure.
