How to Remove Heater Core?
Removing a heater core is a difficult job. It is generally behind the dashboard of your vehicle. Once in awhile you can access it from the floor easily however most cases involve removing some things in order to access it. You should see a box on the firewall when looking up from the passenger floor area behind the dash. Remove those bolts and the cover. Make sure hoses are unhooked in the engine compartment and pull it out then replace it.
