Low coolant, failed thermostat, failed water pump, radiator restriction, etc.
Check the coolant level. Check the thermostat.
could be a sticking thermostat.
heating coil or fan
You probably have a leak in the heater core.
please dont say this question again
Did you bleed the air valve? if you open any part of the cooling system on a dodge intrepid, ie: change the radiator hose or thermostat housing. You need to bleed the air out the Valve. If not the car will over heat.
There are a few reasons why there may not be any heat in a 2003 Dodge Ram 1500. Some of the reasons are a bad heater coil, blown fuses, or even a stuck thermostat.
IT COULD BE THE THERMOSTAT, THE VEHICLE BEING LOW ON COOLANT, OR A MODE DOOR WITHIN THE DASH
The oil sending unit on a 2003 Dodge Stratus is located on the side of the oil pan. It is under the heat shield.
The thermostat may be stuck open, replace it. No ac belt won't effect the heater.
If your car is anything like my 2001 intrepid, it is because only one of your radiator fans are coming on when the temp sensor tells your fans to turn on. You hear a fan kick on, but it is only one of them. There are two.
they leak it is common.on the intrepid the sensor is on the passenger side half way up the block.unscrew it on the smaller sedan stratus etc.it is buried in the back under a small heat shield hard to do unless on a lift
