327 Running Hot!
Hey guys I posted about this a month ago and with your suggestions I have done the following: new high volume water pump, high flow 180 thermostat, moved temp. sending unit to the top of intake, fan correct inside of shroud, fan is stock type looking but heavy duty aftermarket 18" with aluminum blades, correct coolant concoction with water wetter added, new radiator cap, replaced new green line stewart warner gauge and sending unit with new set-------Still according to the gauge its running at 215 - 225. Then I bought an ir (raytec) temp. tool and everywhere I check, thermostat housing, radiator, hose out of thermostat, etc. I don't get a reading over 185! Then I drained out about a quart of coolant and replaced it with a quart of water to dilute it some (it was 50/50) and left the top of the radiator off so I could check for bubbles and watch the water in the radiator so I could see the water ripping through when the thermostat opened but the water never started ripping through. It just slowy, very slowly moves when the water warms but my gauge is showing the temp at 215-225, should'nt the water be ripping through if that was the temp. because my thermostat would be fully opened at that point? But even more screwy is when I put the lazer in the hot water of the radiator it only measures like 150! Is it possible I have a plugged radiator because the water is not ripping through it and another bad gauge also? Sorry I was long winded but I think I've given enough detail for someone to help out. Thanks.
