the infared test was done at a muffler shop here in huntsville.
just finished installing the new clutch (thermal clutch) and i cant get the temp over 180. i havent put a thermostat in yet. and the water has the watter wetter stuff in it. before the trip to nashville i dumped a can in the system and it dropped the temp 20 degrees, i was impressed . now that i look back im lucky to have done same as i probably would have had to fix the weenie for over heating last week end.
the non-thermal clutch looks like the thermal but it is a rpm sensitive clutch. more rpm less friction and fan turns less rpms. it is supposed to turm one for one at low less than 1000 rpm .
we all have a problem with the 454s running hot and when you pull a toad you have more heat to worry about.
your sencet in the block might need replacing . they are not that expensive . i replaced mine before i had the temp checked at the muffler shop. also on my engine the right side exhaust manifold runs hotter than the left side. im going to put a 180 thermostat tomorrow, and hopefully that will be the end of this

Cockpit Heat

I know its an old thread, but it describes what this fellow tried to solve here. - Fresh Air Vents

This alteration leaves no visible outside alteration on your Classic Motorhome, such as a manual reversible vent would.

Fresh air is always better for cooling the body if you can get enough air movement, and this would allow you to keep that noisy window closed. His and hers could be installed as each is controlled individually.
