Question about 2010 Dodge Nitro

1 Answer

Heating problems I have a 2010 Dodge Nitro that hasn't heated well since new. We took it in for warranty three times, having the thermostat replaced, the heater core pulled and cleaned, and the blending door checked. I have not checked the parts myself because of warranty. The only time we can get the car warm is while traveling at high rpm, (interstate, hwy, etc). I know the cooling system is moving freely. Any suggestions on what else could be wrong with the system?

Check for air in the cooling system - tighten carefully all hoses especially ones by expansion tank. If motor on cool down sucks in air instead of water an air bubble could restrict the flow of coolant into the heater core.

SOURCE: Cool air blowing from heater, even when on high.

if the heater core is bad, it will leak or not flow water. even tho you can "hear" the blend door working, it may not be actually moving inside the box. check to see if the actuator is connectd to the blend air door. You may be hearing the actuator moving but not the door.

Was the sludge Orange or more of a tan or brown colour? If there is a tan or brown colour sludge in the rad, this usually indicates a head gasket leak. I would flush out the cooling system and be sure that there is good coolant flow through the rad ( you should be able to see the coolant moving in the rad with the rad cap off and engine running) as well as no air locks in the cooling system. Feel the heater hoses at the fire wall with the engine at opperating temp. The hoses should be hot and close to the same temp. If not then there is a flow problem or a plugged heater core. hope this helps..Good luck.

if your radiator is leaking then i would say you are low on coolant. the heater wont work when the coolant is low. i would see what happens when you get the new radiator in tomarrow.

My heater quit working how do I check the fuse

Do you mean the fan or no heat?. Do you have a temp gauge on the dash and does it look normal? It could be a stick open thermostat.

Where is the thermostat on 2010 Dodge Nitro

Look where the top radiator hose connects to the intake of the engine it will be in that location more then likely there will be two bolts to take out . But let me say this if you have never replaced a thermostat let some one that has help you.. It has to be put in with the cone up and if you are not careful and lose to much antifreeze you can vapor lock the cooling system.

No heating inside cabin , motor not heating , mybe thermostat open nonstop coment

Thermostat is the place to start. Remove the old one. It should be closed when you remove it. Get a Dodge thermostat because on later model cars they need to warm up in a set time frame or you may get an on going check engine light. It will also be the correct temp vs aftermarket which may not be.

2010 Dodge Nitro AC Fuse for fan location

First, it would be nice to know WHICH fan you are talking about. The engine cooling fan? The heater-A/C blower fan?

Second, this might be the time to educate you about fuses. Fuses do not cause electrical failures, Electrical failures cause blown fuses.

With that being said, it is highly unlikely that if you find the fuse you are looking for, that it will solve your problem.
