So, I replaced the coolant hoses behind the intake manifold...since I haven't seen anyone stating the sizes, I thought I would share for future newbies. Also, I went ahead and cleaned the insides of the piping (took it off) with some rust remover.
HOSE SIZING:
The largest one can be replaced with some 1" heater hose
The one behind it (next to largest) can be replaced with 3/4" heater hose
IACV hoses are 5/16"
Throttle body hoses are 5/16"

After reading some IACV problem threads, I might hook those up instead of bypassing which is what's shown. Def. keeping the TB bypassed...What do you think?

Oh, does anyone know of a part number of a hose that worked for the funny shaped hose? I know it's 5/8" ...hoping someone found one of a similar shape; forgot to look for that one!
