Don't know the specifi procedures for your exact car, but here are the general procedures for most vehicles:

1. Drain coolant system

2. Remove glovebox/dash

3. Remove part of the airbox that holds the core (following the coolant hoses through the firewall)

4. Unclamp and fastners/clamps that may holt the core in the air box.

5. Remove two clamps that hold the coolant hoses onto the core.

6. Remove and replace core

7. Install in reverse order

8. Refill coolant

These are the basic general procedures. Take your time and have patience. The difficult job is removing the lower dash and airbox to get to it.

*** If you have a pass. airbag, DO NOT disconnect the yellow cannon plug that may be in the way. Just try and move it.***

Get yourself a Haynes or Chilton Manual for your car< I used both and they give good directions. Most auto supply stores carry these.
