When it comes to replacement costs, engine drive belts are relatively economical, although the price can fluctuate based on a multitude of factors. On average, the cost of a drive belt itself ranges from $25 to $75, depending on the vehicle make and model. However, the total cost of replacing an engine drive belt can rise significantly when you factor in labor costs. Mechanics typically charge between $75 to $150 per hour, and changing a drive belt might take anywhere from one to two hours, culminating in a total cost of $100 to $300 for parts and labor combined.
