It's a bunch of busy work nothing complicated. Remove hoses from core at firewall, remove a clip at firewall that's suppose to prevent the hoses from pulling. Remove glovebox door and back panel, radio, dash trim and then there is like 7 screws holding on the panel underneath the dash and if the dealer did it before beleive me at least 5 are missing. Remove panel and then heater core, replace core and reverse process. There are web pages with detailed instructions maybe someone can direct you. It's really easy but takes time to remove adnd replace all the screws. Then when you go to replace the hoses, the hose that runs from top front of motor, reroute to run right behind A/C compressor and leave some slack in it so when your motor torques it won't pull on the core. Pocket your savings.
