Hi,

The heater core will be removed from the interior of the vehicle. It is located under the dash. When removing it, make sure to cover the area under it to prevent coolant from getting onto the interior components.

To get you started, here is a link that explains in general how it is done. You can use this to help in the process.

If you look below, I provided the directions specific to your vehicle from my manual.

I hope this helps. Let me know if you have other questions and how things work out for you.

Take care,

joe
