Rick,
Here is a thread as to what your coach should have for the fill valve if still OEM. This a DIY on how to clean it out and what to look for. Water Fill Valve Issues
As for as location as David has said it should be hid behind or around the water pump.
Mike
Those were change over years so they hid that valve in different places. If not around the water pump it may be one of the few that is hid behind the fiberglass cover where you hook up your water hose.
