Pulley Diameters

T'stat is a 180* & checked in a pan of water before installed. Lower hose has spring & running a 17" Mopar clutch fan w/ a shroud. 3 core Mopar radiator.

Anything is possible though...it is a Demon LOL :)



I like unedumacated guesses....seems like I'm good at those :BangHead:

So when you underdrive the WP, your WP pulley is larger than the crank pulley correct??

I hate this, but am determined to fix it!!!!

Is it a high flow thermostat? That can make a difference.
