You probably need to burp the coolant - The easy way might be to park up-hill.

I made a signature for you, change if you like. On the overheating there are a lot of things that can cause it. burping is the most common. Use the "Search Community" box above to get other ideas.

I also tried that I going to replace the water pump to see if that is my problem


Sounds like there is air in your cooling system. Did you purge the hemi's cooling system of air via the little purge bolt above the water pump when you filled it back up with fluid?

Get a sure fill funnel from NAPA, 30 bucks. Its like an open funnel that secures to your radiator cap. Fill it, get it up to temp (it will fill up the funnel, be careful). All while squeezing the upper radiator hose to free the bubbles.. And then let it sit until it cools down, being cautious ti fill it with more coolant before it drops too low.

Only way Ive been able to easily bleed the whole system. You might have a bleeder on the water pump but Mine was siezed lol

Also... Steam from the thermostat housing? Make sure that is tight, the upper hose clamp is tight, and make sure you got a rubber o ring gasket around the t stat

With my commander I have found that every time that the radiator cap has been taken off, eventually I would find my engine getting hot at idle, once by me a twice by shops checking my fluids while doing other services. Last time this happened I was just getting my tires replaced the tech had listed that all fluids were checked and okay, and sure enough the next week I started having overheating problems. I did the purge procedure and it is fine again. I don't know if the same happens with others but it seems to be in my case anyway.
