How do you install a heater hose fitting on 2004 Pontiac grand prix gt?

First remove the resovoir tank to have more space. Remove drive belt. Two top bolts and 1 side bolt to remove alternator plus connections( power and ground). Then 3 remove 3 bolts from tensioner housing and remove. Should come out with heater hose fittings. Be careful the fittings could break in manifold. Finally replace fittings and reinstall housing, bolts,alternator w/ connections, drive belt and reservoir tank. Used Dorman heater hose fittings # 47065 from local autoparts store autozone/ oreilly's have replaced them 6 times in past year. 6th was 2 days ago.keep blowing out... its true practice makes perfect.
