You definitely need good instructions and illustrations to tackle replacing the heater core on a car. Autozone have some popular workshop manuals for free on line once you register (for free) on their website .There is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You get a one year subscription to year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual. or try and get an online repair manual subscription.
This site is primarily used to sell manuals and or repair services, fill free to do the work yourself, and bring an aspirin, and your tool box/
it would be nice if they had one for this car but they dont!
