2003 concorde 3.5 overheating

Asked by Jul 17, 2017 at 12:27 AM about the 2003 Chrysler Concorde LX

Question type: Maintenance & Repair

Hello guys, i got this 03 chrysler 3.5 that i
got for free. The car runs fine but
overheats. It has no thermostat but their is
no coolant flowing through the radiator
wich is brand new. I know there is no flow
because the upper hose is at ambient
temp while the lower hose is so hot you
cant touch it. But i am able to have water
go through the engine with my garden
hose at it will run for days with temp gauge
reading below half. I have just recently
removed the waterpump thinking that was
the promblem the its in good shape. Also
put water through the upper and lower
hose with the garden hose to make sure
the pasages to the water pump wernt
clogged wich were not. I have no idea what
the hell is wrong with this car but with the
cooling system full, the temp will rise non
stop until i shut the car off. At that point
the resovoir is boiling over. I dont belive
their is a bad head or head gasket as the
oil is pretty old and it does not have any
water in the oil. Any ideas, could it just be
air in the system. Also with even the temp
over half of gauge, i get no heater in the
car.

Just curious why are you trying to operate car with no thermostat? I'd suggest going to the auto parts store getting some anti-freeze coolant that is compatible with your vehicle, putting a thermostat in and refilling the system with coolant at a 50/50 mixture.

No heat in the car from the heater is a dead give away pointing to a massive air pocket, I have had a couple of these that I wound up using a flush machine on to get the air out, some times they just would not bleed the air out, most of the time they will work just fine then there are those that are just problems. And Brian is right you must run a thermostat, it not only slows the coolant speed down when things are working right but it also has an effect on engine performance, some won't go into closed loop so you won't be getting the benefits of the electronic controls cause the computer thinks it's too cold.

I do plan on putting on the thermostat. It did not have one when i got the car. I aready have a new one but i need to buy the thermostat gasket.
