Well I ordered a Haynes, but it's not the same quality of some Haynes manuals I've owned in the past. That said - using about 3-4 different uploads from bobbyg from your site/links, I was able to get things pulled apart! So thank you so much for directing me there.Have a look at this document, full engine teardown, scroll to the section of the document for the coolant system (starts at page 61).
That guys has shared basically every manual related to this generation of Santa Fe. Very helpful!
