New cooling system, still overheating.

Basically all over.
Radiator hose, both upper and lower.
Radiator in different spots.
Water pump.
Intake.
Thermostat housing.
Engine block and heads in different spots.

What you are looking for is how much variation there is. Say the intake is really hot and the upper radiator hose is, really cool then the thermostat would be worth checking out.

They didn't have the leakdown tester so couldn't do that.
But as I started my truck to back out of Autozone, clouds of white smoke came out like I was stoking a beehive.
And it stumbles when I first start it up. To me, that sounds like it has water in the cylinders.
I don't want it to be, but it sounds like it is.
