Q: Their is a hole in the Heater Box

If you are referring to the "heater core", which is the metal assembly under the dash that looks like a mini radiator and through which heated coolant flows, for your make and model that part costs anywhere from $75 to $250 depending on whether you buy a genuine OEM (dealer) heater core or an aftermarket heater core. Obviously, the OEM core is preferred as it will fit and function as well as the original. It takes roughly 3 to 5 hours to remove and replace the heater core. To get a precise estimate of the cost, please request a heater core diagnostic and the responding certified mechanic will estimate this exactly for you, based on whether you want the OEM core or an aftermarket core.
