The average cost for replacing a timing belt depends on the make and model of the vehicle. According to CostHelper.com, the cost for passenger cars varies between $179 to $942, with an average cost of $449. A timing belt for an SUV or minivan costs between $502 to $950, with an average of $736.
Much of the cost of timing belt replacement can be attributed to labor. The belt itself is generally not expensive, but accessing the timing belt and evaluating the condition of other internal parts can be labor intensive. Labor costs can run from $40 per hour to well over $100 per hour for high-end vehicles.
