I did my heater core last year, 2011.
Found lots of repairs done wrong in there while I followed the service manual. Thoroughly cleaned everything as I went.
It took a total of 9 hours, over a Saturday and a Sunday.
I had my parts supplier get the OEM hoses for me. Glad I did, as the ones on the car were either hard as a rock, or mushy.
I washed the entire heater box assembly, cleaned the flaps and surfaces. Previous owners were smokers, and it showed.
I'm so glad that I went ahead and did this job. Everything is working properly, and more importantly, there are no rattles in the dash anymore!!
