98 dodge dakota slt 318. no heat, low operating temp

My truks fan runs continuously, the heater blows lukewarm air, the temp gauge does not rise at all, the lower and upper radiator hoses and radiator cap do not get hot. I am low on coolant. but i think my last mechanic has my owners manual so i am unsure to add coolant while cool or hot. why is my fan runninng constantly even though the engine is staying cold and if i am low on coolant shouldn't my engine heat up faster?

    If after adding the coolant, it just keeps circulating. wouldnt that show a thermostat that is stuck open? Again, why would my radiator fan run even though the engine is cold?

    the coolant low almost every week and recently, I noticed the coolant boiling after driving for about 10 miles. I thought the radiator fan wasn't working but I checked later and it was working

    eveything works but why do i need heater to keep engine temp right

  • Anonymous Mar 21, 2014

    could it possibly be a stuck thermostat or blocked radiator

    My 2004 Dakota is loosing coolant but I can not find any leaks. I have replaced all cooling components except the radiator. When I drive to Seattle and Back (about a 6 hour drive round trip) The overflow tank is always full but the upper radiator hose is empty and it takes about half a gallon to fill it up. Has anyone else had this issue? What was the solution?

    Engine tempature is normal. Fan blows. Coolant levels are normal.

I would try flushing the heater core first,it's a very easy job,if thats not the problem then it's most likely your thermastat.hope this helps you,i know that worked on my dakota.

First thing first, turn off the engine wait for 15 - 20 mints, open the radiator cap and fill it up to the top then start the engine and see if it needs more water adn add as needed, then wait till you ca see the water circulating in the radiator now instead of corculating if it starts boiling out shut the engine replace the thermostat and do the whole thing again.

unless there is water in the engine the gauge will not be able to show the actual temp of the engine, so always malke sure you have water / antifreeze

No heat coming from the vents.


If it is a manual system--sounds like coolant low ie: air bubble in system. If it is ATC system, Check Codes, if no failure codes, coolant may be low--air bubble in system--most Durango's have air bleeders in system.

Heat goes in and out and the temp gauge goes up and down


Your temp sensor has nothing to do with your heater. The temp sensor needs coolant in order to work properly. So first check the coolant level because if it is low your heater will act the way you describe. Once the coolant gets low enough the heater will blow cold. Another possibility is the radiator cap. After the engine has warmed up it expands when it cools down it contracts. As it is contracting if the cap is weak air can be drawn into the system and cause air pockets to form and will cause the same problem

Heater blowing only warm air, fan is fine. no leaks on heater core where is the control for the heater located


Make sure you have the coolant level at the correct level in the bottle resorvoir. If there is not fluid to circulate in the system, the fan will only blow a cool or lukewarm temperature air. If there is enough coolant, check that the water pump is working.

My truck starts running hot then I turn the heater on and it blows cold air but every once in a while the heater will throw out hot air. Then the temp gauge will go down. I've check med the radiator cap...


I'd still check the thermostat. Or basically just replace it. Have you ever drained all the antifreeze and flushed the system? Good time to do both. If the hose's get real hot that doesn't really mean the thermostat open. Wouldn't they get hot even if the thermostat didnt open.? If the thermostat was stuck open you'd would have cold air and low temp gauge. Then maybe hit a pump or something and have the thermostat stick closed and have high temp. Maybe water pump. Check it when you have the belt off. Spin, pull & push the water pump pulley around. I'd replaced my water pump at about 110,000 on a '97 dodge Dakota. My 97 never had a very good heater. Always heated up more after driving. Idle never got it warmed up.

I have a 1998 Dodge Durango SLT-V6 that has no heat.


The heater core might need back flushed, I just did mine this winter. Go to dakota-durango.com and introduce your self and your rare as ever truck, a v6 durango, and have fun.

Heater does not work


Check blend door motor for proper operation (vacuum operated) if necessary, detach arm from heater box and move by hand. If you have heat then, change motor! You are reaching operating temp for engine, right? If not, thermostat is stuck open... Change.
