Hello,
I would like to know which way the heat riser opens on a 75 Chevy C-10 Pickup with a 350. Clockwise or Counter Clockwise?
I seem to feel more pressure when I turn it Clockwise and it seems to have more free flow when I turn it Counter Clockwise but I am not positive. I can't seem to feel any difference at the tail pipe. When I turn the heat riser Clockwise it seems like it's fluttering inside and I am assuming it's closed. When I turn it clockwise, it seems to have no restiction. Is this correct?
Thank you,
John
