The radiator is most likely plugged. Flushing is the least expensive way to try to fix the problem. It may not clear a severely plugged radiator. Watch the lower radiator hose with the engine running. Accelerate the engine. If the hose tries to collapse, then the radiator is definitely plugged.
Sensor would just cause a check engine light and radiator caps hardly ever go bad. It's possible you put the thermostat in upside down. Also possible that a hose is clogged. More than likely you have a massive air bubble trapped in the engine block.
Sorry to say, but these are classic symptoms of a failed head gasket. Those bubbles are probably exhaust. Check the oil as well, coolant could be leaking into it. There are test strips that can verify this by dipping the coolant.
With the engine cold remove the radiator cap. Top off with coolant. Start the engine and let idle topping off coolant as necessary. When the engine is fully warmed up and you feel heat coming from the radiator fan replace the radiator cap.
I hope I am not corect but the dodge engine Mitsubishi has aluminum heads easy to warp and overheat I had three dodge engines with warped heads go for anywhere form 600 head refurbished to 800 remanufactured heads replaced not dealer shop price that would be 1200 to 1600 minimum find a home mechanic have him check the head for warpage do you smell steam sometimes ?? It is a symptom I replaced water pump ,thermostat ,radiator cap, resorvoir , prayed ..prayed but it was the head warp deal ... you can do this yourself BUT replace head bolts and gasket A must when you re install the head
1. With what you have replaced, the only remaining credible explanation is the Water Pump. If the Water Pump is not operating correctly, this will cause overheating. The Radiator -"side blow out"? Did the radiator cap you have on not work. Overheating should cause fluid = steam to blow out the cap and not blow out the side of the radiator.
2. One thing you can do before replacing the Water Pump is to flush your entire system. There could be a blockage in the system. These flushing kits are available at most stores (Walmart or Autoparts Stores) and you can do it yourself.
3. Was the Engine Coolant Temperature Sensor (mounted near the thermostat) also changed out? If this was malfunctioning it could be giving you a false reading.
The Water Pump is the likely culprit if the Van is truely overheating.

Don't know what you are testing by squeezing things but if lower hose is cold ant upper is hot, change the t stat. If problem continues then it's likely that the radiator is still obstructed and needs to be replaced (sometimes flushing will simply go around internal stoppage).
i had the same problem, i dont remember the name of the piece but its mounted right in between the driver side headlight and the radiator. its a relay that turns the fans on when the car gets hot. its mounted on the body of the car. there should be wires leading from the radiator to the piece im talking about.... good luck I also paid about 35 dollars for the piece
