How long should it take to change a heater core?

Answer 1

This is one of the most labor intensive repairs you can do to an automobile when you compare the parts required. A heater core is not that expensive, and is easy to replace, except getting to it, it not easy. It may take up to 4 hours to replace. It depends on the vehicle you are asking about. There is no "How long should it take". Fact is, it takes what it takes. Someone that has replaced one on this same vehicle can do it much quicker than someone who has not. Knowing exactly what to remove and how, takes experience. So be prepared to be shocked at the labor costs. It is never cheap. A $60 part may cost up to $300 to replace.
