SOURCE: 2002 dodge 1500 Changed radiator, thermostat, and hoses. No heat

Why was radiator replaced?Did it have heat before ? If it was plugged, the heater core may also be plugged. Try flushing it with a water hose in both directions. I dont know why the botton radiator hose would be cold, the radiator should be a uniform temp and the air coming through the radiator should be HOT, when the engine is at operating temp. What condition was the old coolant? if it was rusty, the water pump may have lower flow than normal.

2003 dodge ram 1500......no heat


Does your heater motor run when you turn speed dial ? Have you checked the two hoses that run from the engine compartment to the heater core ? When car is at operating temperature, carefully touch both hoses which should be warm or hot. If only one if hot, then you may have a bad actuator. If both are hot, you may have a clogged heater core or none functioning heater motor. or resister.

If motor is not working, check fuses, if good, then check for power at the switch and then at the heater motor.

Thermostat and engine heat seem fine, seems that heat knob, gears and cable are all working fine, but have practically no heat from heater.....96 Dodge Ram 1500 4 x 4. No problems with ducts switching...


Hello. First, does the fan speed work correctly? When you put it in the high possition does the air come out faster?, if so, raise the hood, look back on the firewall, ( behind the motor ), and locate 2 hoses that are about 1 1/4 inch in diameter that both hook up to pipes on the firewall. This is your inlet, and outlet for your heater core. I suspect you will find that these hoses have been joined together to bypass the heater core. Often when a heater core is leaking people don't have the money to replace the heater core, they generally cost $300 to $400 and sometimes more, then you have to pay the labor, in some cases, to remove about half of the dash to get to the heater core. This repair can be expensive indeed, so, often people just bypass the heater core by joining the inlet and outlet hoses of the core directly together skipping the core altogether.
Good luck!

How do you get a dodge 1500 2003 heater core out?


Well if your 1500 is any thing like my 03 2500 hemi 4+4 then you need about six hours of free time. The heater core is behind the passenger side dash area you have to first begin to take the front dash all the way apart and I mean all instrument cluster drop steering wheel from middle support bracket after that you will disconnect the ac lines into firewall this is not easy task but can be done with specialty ac tool then in both sides passenger four bolts on each side take those the whole dash can then be pulled back far enough to take two hoses of heater core and in engine compartment four bolts hold it in then follow steps to install

Heater blows but no heat in my 2003 dodge ram 1500 4x4 with 4.7L engine. what can this be? its a 2003.


If your engine reaches normal operating temperature then it sounds like the heater valve is not operating. Find the valve on the engine firewall passenger side and manually open the valve. Find it by following the 3/4 inch heater hose to the firewall where it is connected to the valve. Most likely the cable ( or vaccum hose)from the temperature dial to the valve needs replacing.

I have a 2002 dodge ram 1500 pickup w. hwat issues


is this a problem w/ the interior vents? maybe stuck venting in outside air rather than from the heater box? did the heat only stop working after the radiator/hose install? if so, then you probably have a big air pocket stuck in the heater core.

No heat


You probably just need to backflush your heater core. You can use a hose to flush it back and then forward. You'll be surprised at how much sludge and gunk will come out.
