How do i replace 2006 buick allure heater - Vehicle Parts & Accessories

If you are speaking of the heater core it is located in the center of the dashboard inside of the blower housing. You will have to drain the 134a from the air conditioner system, drain the coolant, remove the center console, remove the radio, remove the bolts that hold the dashboard in place, remove the dashboard and set aside. Remove the heater core box, remove clips and split the box, remove heater core from box, reverse procedure to install. Just a note heater core removal is one of the jobs our shops get from other shops meaning that even professional mechanic shops don't like to do this job. Make sure the person who is doing this job is well familiar with this type of work or you will be listening to a bunch of new rattling noises from missing bolts and broken clips.
