When you fill the radiator, did you make sure the car heater was set to Full Hot? If not, there could be an airlock in the water system. This can give the symptoms you describe.

sadly it sounds like you have a blown head gasket...Does the coolant  smell like exhaust?  I hope you don't but, everything points in that direction.  Try bleeding the coolant system.

Did you burp the air out of the system after changing those parts? It sounds like the thermostat isn't opening which is why the lower hose is still cold. Click my screenname, go to my tips and tricks, and choose the one about burping the cooling system - it may help you out.

If it is fogging your windows, you have a leaking heater core. Dash removal is required to fix it.

Dodge durango 2004 hemi running hot

You need a radiator. The cores are plugged. Flushing will not help and if you flushed the cooling system when coolant was filthy and rusty everything is now in radiator cores.

Dodge durango 2004 hemi over heating after all the repairs i have done new radiator,water pump hoses , clutch fan, radiator cap and 3 different thermostats,

The cooling system has to be bleed of air.To do this locate the bleeder on the coolant inlet on engine. Remove the bleeder and the radiator cap, fill with coolant until there are no more air bubbles coming out of bleeder. Top off resivor close bleeder replace cap. Start and let it get to normal operating temp, If all is good now you are finished. If it still overheats let it cool off until there is no pressure on upper hose .Carefully remove cap and repeat bleeding process

My 2000 durango keep overheating and the hose keeps bursting. the waterpump and various other parts have been changed. The radiator does not have a leak. The pressure in the radiator is said to be fine....

if it has the 4.7L engine they crack cylinder heads and the compression from the engine put air into the cooling system you can buy a tester that you hook up to the cooling system that changes color with exhaust fumes auto parts stores can get it or stock try napa

I have a 1997 4x4 blazer 4.3L, and I would like to have an exclusive oil transmission cooling system instead the actual beside-inside the water cooler radiator. So, I want to know wich of the following...

Transmission Fluid gets changes every 30,000 miles
on all vehicles

You can by pass the radiator cooler and put a trans
cooler in front of the condenser

Lot of work making the brakets and making it nice

The approx 7"x11" stacked plate cooler is what you
want,not the cheap tube and aluminum fin junk

Use Power Steering Cooler Hose,not fuel line

Problems with a replacement radiator.

check that shroud difference is not a fan to core 'clearance' issue.
1. drill new holes in shroud ?
2.fabricate a bracket out of strap steel to bolt them together ? 3. go back to advanced auto for heavy duty ready shroud ?

Does the cooling system from a 2002 Grand Cherokee can be purged. It's heating; there's no water leaks at all.

I usually will flush a cooling system when I change radiator fluid every 3-4 years. There are many ways to do this, I frequently will just open the draincock on bottom of radiator, run engine, and allow to drain out with a hose in the radiator to replace. This works better if you pull the thermostat, and it's always nice if you actually drop a hose from bottom of radiator to drain.

Oh, and while running engine and flushing, make sure heater is on full hot to flush the heater core.
