#62 of 94 Poor heat 2000 Dodge Dakota 4x4 sport
Dec 05, 2009 (3:27 pm)
Hello to all, I got a heat issue with my 2000 Dodge Dakota 3.9L. The truck puts out warm heat. I checked the anti-freeze, put in new thermostat and checked the heater core. They all seem to be working fine. The hoses that go to the heater core are warm, where I think they should be hot. The truck is running at operating temperature. Water pump sees like it is working fine and circulating the water.

I have a 2000 sport v6 with over 300,000 km on it. What you describe is a leaking heater core. I have just put in the 3rd one. Not a job for the meek.
I am actually reading through this to see if anyone else has had experience with 2 heater cores going bad, first one original mopar part went after 250,000 km. second one went after 14 months (12 month warranty on the part) and was an aftermarket copper heater core.
New one is an aftermarket aluminum heater core. Part is about $40 (US). Labour is 8+ hours.........
I want to know if anyone else has had any luck in trying to determine possible causes?
I check for electrolysis (none to speak of, cannot remember actual reading)
Suggested too much pressure in system. Rad cap is original and has been tested. Rated at 21 psi and still good according to test. local garage says it should only be 18 psi. Cannot confirm this.
I was also told that it was running cool. (195-200 F) cannot confirm correct op temp either.
IMO if pressure is too high than temp should be too high too?
can anyone elaborate or help with trying to prevent a 4th heater core from being installed.....

Also have a 2000 V6 sport.
I have a subscription to AllData and also checked an online resource link title
I could not find the code P0045 either. Not saying it doesn't exist, just cannot find any info about it.
I do get a code somewhat regularly which is P0455, Large evaporative leak detected. Usually goes away and cannot find the real cause. Sometimes gas cap isn't on correctly or the evap. canister has issues. I believe dusty has dealt with this more thoroughly than I have (or want to)

#67 of 94 Evaporating Radiator Fluid
Jan 01, 2010 (1:10 pm)
I am having issues with a bad burning smell of radiator fluid, but I cannot locate a leak. I have a feeling that it may be related to my heater core as I can smell it through the vent in my cab but regardless, fluid level is consistantly draining and now the truck is having problems idling (maybe as a cause of this radiator fluid problem.) Cab floor is dry (as I have noticed that a bad core may leak on the cab floor.) Oil has a good consistancy, (no froth.) Anyone have an idea?
#68 of 94 Re: Radiator On Dodge Dakota is Holding Pressure
Jan 05, 2010 (6:52 pm)
Can someone help me please? Does anyone know what would cause the radiator in a Dodge Dakota to hold pressure even when it has been turned off all night long? And also, is the water pump supposed to be turning clockwise or counter- clockwise when it is turning? Thanks to all for your help. - Wayne

Not sure about what direction the water pump should turn.
On the radiator pressure - keep in mind that much/all of the pressure increase in the cooling system is due to the coolant heating up when the engine runs. Once the engine is off and cools down, the pressure should pretty much return to what it was before. That's why there are warning notices posted around the radiator to not remove the cap unless the engine is cool.
#70 of 94 overheating on 2001 dakota with the 4.7L
Aug 15, 2010 (12:03 am)
yes, i have a 2001 dakota with the 4.7 its a quad cab and 2wd, it has an overheating problem. ive replaced the thermostat 2 times, water pump, caps, belts, fan clutch. its weird because it only overheats when going below 40 mph but when you speed up it cools off to normal temp range. im wondering if my electric fan on my radiator is going out or maybe ive blown a head gasket, any ideas how to check the fan? ive already looked for leaks or coolant in my oil and found nothing out of the ordinary. its also been starting rough, its only rough at start then it idles smooth. any ideas?? thanks

To check the fan, disconnect the connector to the fan and CAREFULLY apply 12V across the input terminals to the fan using a battery charger set on low (couple of amps max output) or a current limited power supply
Could also be the fan relay.
