lets see, yes the water circulates, my instrument cluster has a digital speedometer, gauges and dummy lights combined. It overheats with the tstat out and in; and I read on one of the other posts not to run a lower degree tstat because it causes a continual open loop. So, last night I put the 190 degree one back in and it overheats in less time now. I will take my water pump back and get the reverse rotation and see what happens. Thank you all for your insight and thoughts. ;)
