Heater problems 2009 dodge nitro v6.

Possible, with rad cap off, let vehicle idle until coolant fan comes on then shut vehicle off for 30 minute cool down. Top up rad, install cap and drive and recheck heater operation and any overheating.

2004 dodge ram 1500 overheating on the freeway

The 2002- 2007 Dodge Ram 1500 4.7 L. has a single core radiator with flat fins that become easily plugged with scale and other stuff floating around in your motors cooling system. Since these fins are so small about .040 of an inch good luck flushing out any clogged particles by doing a flush. Many of the online part stores have replacement radiators for less than $120.00 (Rock Auto, for example). Replace the radiator with a new unit. Make sure to flush the engine block and heater core before connecting back to new radiator. I completed this job over the past weekend in less than 3.0 hours start to finish. Have less than $220.00 in all hoses, Thermostat, Radiator and new coolant.

Heater No Heat

Hi my name is Allen!

If both sides of heater core hoses or to hot to hold on too then your heater is OK, but if one is to hot too hold on to and the other is just warm and you can keep holding it then you have a restricted heater core.

NOTE: If both or to hot too hold, then you have a door problem. If you change the temp door and air flow feel the same, then you could have either a bad motor or a broken door.

NOTE: We have seen a lot of broken doors on this year model, if you can reach the motor for the temp door and take it off. Then you can turn the lever and if it keeps turning you have a broken door.
