Well, I put a set of gages that a friend has on but we aren't too sure of
what it should be. He thinks the low side is where it is supposed to be and the
high side looks normal at ideal but at higher RPM's it goes to what he thought
was too high. Sorry I didn't right down the numbers.
Bernd both of what you say is happening. When the outside temp is above 95
the clutch starts to engage then it pops off and will not engage . As the
outside temp goes down when you turn it on the clutch engages and it blows great
cold air.
Does this help give anybody an idea of what to change? Or what to test to
figure this out.
Thanks
Bill

Jesus once said to his followers:
Daily you must trust Me, surrendering everything, including the blood in your
veins and the breath in your lungs, for Me to do with as I see fit. If you
want to join up with Me, you must let Me lead. Luke 9:23 (Eric Ludy paraphrase)
