Recently purchased my 2006 Ford Taurus from a dealership about 7 months ago. In late October I noticed a big puddle of liquid in the passenger side floorboard of my car--we had had 2 days straight of heavy rain (Seattle!) So I figured maybe there was a leak in the hood and water was getting through and leaking into my car--(shows how much I know about cars). Anyways, in the beginning of December the puddle happened again and it had been raining all weekend as well so I thought it was the rain again. But I called a Ford Dealership and inquired and they told me it was the heater core and that my car was not driveable and if I continued to drive it I was going to overheat the car and possibly blow the engine. They also told me it was going to cost over $700.00 to replace. I found a mechanic to disconnect the heater core for me.A temporary solution to a big problem. My dealership warranty ended after 3 months. I am trying to find fault with them. How could a 2006 Ford Taurus with only 30,000 miles (had 30,000 when I purchased it) be needing such a huge repair at this time? I am trying to figure out wear and tear of the heater core and things of that nature.

Thanks so much!

Hi,

Replacing the heater core on this vehicle is a somewhat big job. However, take your time and follow the directions and you should be fine.

To get you started, here is a link that explains how in general it's done. You can use this as a guide.

https://www.2carpros.com/articles/replace-heater-core

Below, I attached two different sets of directions. The first explains how to remove the instrument panel and the second is specific to the heater core.

Let me know if this helps or if you have other questions.

Take care,

Joe
