Its not elevated enough but the upper hose is getting warm, bottom hose still cold but the water in the radiator is warming up as well. Very frustrating

tried elevation and also ran with heat on, heater hoses warm, lower hose cold, upper is warm, temp past 210 shut off. I think I will pull the thermo stat and test it. :bang:

I pulled the thermostat and started the car, same result except I got water through the lower hose. There must be a nasty pocket by the water jacket or????? Thanks

One thing I usually do with new stats, is drill a little air bleed hole in them to help with those issues :)

Thanks, I will test the sensor today

The last thing I thought was bad was the gauge and sure enough, before the water reached a boil the gauge went to 250. Time to call auto meter, that was a hateful two plus weeks. Thanks I will let you know how the new gauge works out.

Are you using the autometer temp sensor? It won't work with the the stock LS sensor that the ECM is using. You need two sensors.

I am using an auto meter temp sensor where did you come up with two sensors? Thanks

What temperature sensor is your engine controller using? Are you using the GM controller?

Quite often guys use two sensors, one in each head.

I would think you have a factory sensor on the driver side forward in the cylinder head. I run the auto meter sender in the passenger rear part of the head. If I recall you said the fans sensor is in the radiator.
