Just curious, did you install the wrong rotation pump? Or are you thinking about it?

I would imagine you would run into some kind of heat issues, but I'm not sure.

This is why it is important to check what you bought against what you have installed before installing the new pump.

Overheats like a big dog.

Sure you don't have air in the system?

How much coolant did you put in before starting it?

Ok it runs at about 220 so I guess its not the water pump.
I installed new radiator, water pump, t.stat, fan clutch, hoses...so I guess theres still air in the system?

It should have ingested a little over 2 gallons of coolant when you filled up....

You should also verify your gauge is correct by aiming an IR temp gun at thermostat housing when it's warmed up.

If it took over 2 gallons, there is no air in the system.

Have you let it cool down and started it up again?

I installed one of those safety thermostats with a fail safe that keeps the thermostat in the open position if it gets to hot. When I started it up today it took forever to warm up indicating that the thermostat has reach the temp where it stays open.

Get rid of that.

They're problematic.

Save your money. If you want to burp your system, put the left front wheel up on something (a car ramp, a curb, or something), pop the radiator cap off, and run the engine until the t-stat opens up. Add coolant as needed.

That's it. It's really that simple.

But as Curry said, verify the temp before you throw money at this. Gauges are known to lie.

So I ended up bringing the jeep to SPEEDEE oil changers and had them diagnose the cooling system, they said everything is working good and how it should be and that there is nothing wrong. There was never anything really wrong. I just find it weird that all parts of my cooling system are new and the jeep runs warmer than it did with all the old rusty parts and coolant.
Before the jeep ran just below 210 when driving and at 210 when just idling like sitting at a red light or in a drive thru.
Now the coolest it runs is 210 and 220 when driving.

Remove the temp sender/sensor and clean the probe(3M pads work). If that doesn't help your reading either verify the temp with an IR gun(borrow one?) or replace the temp sender/sensor.
