The cost of labor for an engine replacement on a car can be as low as $50 or higher than $200 per hour. The exact figure depends on the length of the job, which is typically between 15 and 20 hours on modern vehicles, and the hourly labor rate of the shop.
Hourly labor rates vary according to the type and location of repair facility, but are usually lower at local garages and higher at dealerships or specialists. The amount of time necessary to complete an engine replacement fluctuates depending on the vehicle and the type of engine. Engine replacements on older vehicles, which have fewer electric components and connections, tend to take less time.
