What's the cost for a 2004 Ford Expedition heater core replacement?

You could expect to pay anywhere between $750 to over $1000 to have the heater core replaced in a 2004 Ford Expedition. The parts required to do the job cost between $100 and $200 the rest of the costs are for labor charges. In my opinion, it is well worth the cost to have the heater core replaced by either a shop or a dealer. In order to replace the heater core, pretty much the entire dash must be removed from the car and it is not a fun job to do. You are going to need various wrenches, sockets, pry tools and screwdrivers. On top of the tools, You are going to need a couple days to do the job, especially if You have never done it before.
