G..G..G..Granville.........!! Fetch your cloth.
To get the correct Part Numbers for hoses a machine Serial Number would be a great help.
For coolant that machine was designed to run on DEAC, but TBH if you are going to flush it and get rid of all traces of what's in there now I would go for a 50/50 premixed Extended Life Coolant (ELC).
