yep tried that got a lot of air out but in the morning the res. was only
half full, this morning it needed maybe 8oz. of water to fill to the top I
bet that does it

thanks Dave for the website I checked there found a few fan switches but I
think I'll see how it does I'm getting tired of working on it,hehe. If it
stays below about 205F during the hottest time of the year here (now) I
think I'll leave it be.

It's still setting a code, P0420, "cat. efficiency below threshold" when I
'get on it' I've replaced one O2 sensor on that side (heater circuit
problem) will replace the older one in case it's not matching well with the
newer one, cat and muffler seem to be okay no rattles, reduced flow, sound
difference or innards coming out as I can tell. A counter guy at the local
auto parts store said sometimes a faulty gas cap can trip various codes like
this one but I put a new cap on it when I bought it just a month ago so I
doubt it's that.
