Over heating 2002 dodge intrepid

check fluid level --water pump -thermostat-cooling fans

either a heat switch is not switching heat to the compartment or else the thermostat in the cooling system is defective. when it is not open it does not let hot water to the internal heating system, has your engine been overheating or running hot? also as this would be a symtom.

sounds like a stuck thermostat. It is over heating

CHECK COOLANT SENSOR WIRE CONNECTOR MAKE SURE ITS ON TIGHT NOT DAMAGED.IF ALL IS GOOD.YOUR COOLANT TEMPERATURE SENSOR BAD CAUSING THE COOLING FAN NOT TO COME ON.

Ensure your cooling system is full.
With the engine at operating temperature feel the heater hoses going into the firewall. They should both be warm.
If all that is ok inspect the heater temperature door. The door that operates when the heater valve is actuated.

hi is the water flowing through the engine ie radiator blocked, water pump. regards

Since your blower is working and it is a heat issue,thats where we'll start,First thing is have you checked the coolant level in the radiator when engine is cold,make sure it is filled to top,next verify you have coolant in reserve ,Start your van and get it up to normal operation temperature,If your heat gauge on the dash works correctly it should be 190 degrees,Now lift the hood and locate the two heater hoses going into the heater assembly at the fire wall,Both hoses should be hot to hold on to,if both are hot and no heat inside your problem will be the blend air door in heater assembly.
if neither hose is that hot you need to replace the thermostat in the engine to get it up to 195 degrees.
if one hose is hot and one is luke warm then the heater core is blocked and to blame. hope this helps you.

Make sure when you add coolant to system, that you have heater running while filling it and be sure to bleed all air out of system. Keep a real close eye on coolant level for a while as you may have caused worse damage, and if you keep having to add coolant. It would also be smart to change thermostat before refilling system, but if not, keep a close eye on temperature gauge for a while to make sure it doesn't go too high, or jump erratically from cold to hot, indicating faulty thermostat. Check oil often as well.

Radiators do not "go out". They leak or they don't... that's it. You wasted money changing a radiator if you aren't loosing coolant. The thermostat (~$10) is all you needed to change.

The first thing i would do is replace thermostat and bleed cooling system, then re-check, It sounds like you have a defective thermostat.
