I have a 95 gmc jimmy it has started overheating and I found a radiator hose was leaked and started to seperate and there was a leak in the intake. Both fixed however it seems to run hot smoke out the exhaust.I have a head gasket for it and am getting ready to replace it but not sure if it will fix the problem

What do you mean by "hot smoke out of the exhaust"? If you are suggesting an engine overheating problem, then you are only looking at the coolant temperature. If you are seeing smoke, what color is it?

Exactly. You're asking my why your truck is overheating when it really isn't overheating.

You may have a coolant leak somewhere causing steam and that may eventually lead to an overheating problem but right now you're looking for something else.

Pressure test the cooling system to find the leak.
