87 dakota over heating

May need to bleed the air out of the system after the hose change. Look for small bleed valve on the top engine or cooling hoes/pipe bleed slowly while engine is at operating temp, then refill after reservoir after car cools down

You have problem in 1) Your air flow system have gone down and some plastic valves that opens to cold position or to hot position is broken. Solution: remove panel and check this plastic valves that controls airflow.
2) Your heat salon radiator is very poor and can't blow in all directions. Solution: replace salon heat radiator.
3) Your cooling system don't have good limit of coolant. Solution: fil it to min - max position.
4) Your cooling system isn't bleeding. Solution: make system without air in it.
Hope this will helps.

Hope you didn't break a nail.

There is a air pocket in the heater core, you just didn't burp it right.

Try this

1. Open the hood of your car. Secure the hood with the safety handle. If you have a newer car, you should have a bleeder valve on the front of your radiator. Check in your owner's manual for the location of this valve. If you do start your car, open the valve with wrench and let your car heat up. The excess air will bleed out of your cooling system. Keep your car on long enough to give the (trapped air) time to bleed out of your system.
2. Let your car cool down. Once the car is cool, take off the radiator cap. Did the level of the radiator fluid go down? If it did, it means you bled the air out of your cooling system. Replace the radiator fluid, turn on the car, and let it run. Replace radiator fluid as needed.
3. Step 3 (above) is the way you will remove air from your cooling system if you do not have a bleeder valve on your radiator. You will leave the cap off the radiator. You will run your car until it heats up. As the air dissipates, the radiator fluid level will go down. You will fill up your radiator fluid to the correct level. Be careful because the heated radiator fluid will be hot. Always wear leather gloves and safety goggles when working on your radiator.
4. Once the air dissipates and you fill the fluid, shut off the car. Let the car cool down. Once the car is cool, put the radiator cap back on the radiator. You may have to put more radiator fluid in the radiator. The level may fall as the car cools down. Now it is safe to drive your car. You have removed the trapped air from your cooling system.

Tips:
Always wear gloves and safety goggles when working on your radiator.
Radiator fluid gets very hot when heated.
Check radiator fluid periodically.

look at your top radiator hose is there a small bleed valve at the top of the thermostat housing when the upper hose attaches to? If so loosen the bleed valve and allow the cooling system to purge the air out of the system you can tell when the air is out of the system when a steady stream of coolant starts to flow out of the bleed valve, if there is no bleed valve take the top radiator hose off of the engine side and allow the cooling system to purge the air out through the top of the engine that way

1. This method works best if the nose of the car is raised as high as possible. Park your car in your driveway. Let your car cool down. When your car is cooled down, you are ready to work on the cooling system.

did you do anything which may cause a vapor lock? if you suspect there is, you need to park your car upwards on a hill or raise the front of car, let it idle and try to bleed system with bleeding it while heat is on inside. while bleeding it you cna try to squeeze radiator hoses too.

Theres a strong possibility being you just changed the coolant a few weeks ago that theres air in the cooling system not allowing the coolant to cirrculate properly, look at your top radiator hose is theres a small bleed valve at the top of the thermostat housing when the upper hose attactes to? If so loosen the bleed valve and allow the cooling system to purge the air out of the system you can tell when the air is out of the system when a steady stream of coolant starts to flow out of the bleed valve, if theres no bleed valve take the top radiator hose off of the engine side and allow the cooling system to purge the air out through the top of the engine that way, but it definatly sounds like theres air in the system not allowing for the cooling system to cool properly...

YOU MAY WANT TO CHECK THESE FIRST
make sure your radiator is clear and not blocked in any of the fins and openings and make sure your fan is working

u may need to flush the cooling system-could be blockage somewhere
bleed valve should be on bottom of radiator on right side looking at front of truck
if u still can't find it just remove the bottom hose on radiator-make sure engine is not hot before doing this
u can buy flush kit at any auto store
after flushing-put water if-not antifreeze
run for 15 to 25 minutes and see if it gets hot
if not-drain and put antifreeze in
if it still gets hot you may have gasket problems allowing fluids to leak out or hot gases from exhaust to get into you're cooling system
check tail pipe for steam

good luck

try bleeding the cooling system

Where is the thermostat in a dodge dakota 1992 located? Flushed it yesterday still just have heat blowinf ti side vents rather cool windsheild defrost. Maybe there is another problem?
