You have to verify if you have residue from coolant near the EGR below the composite air intake. If you are adding coolant and the car engine still have power then your coolant is vaporizing out and not in into the engine block. Otherwise if the coolant leaks into the engine block the car will act jerky since water is not compressible. Check the oil to see if it looks like coffee color (happens when water and oil mix).
No matter what be prepare to replace the lower/upper plenum gaskets, air intake and the tube that connects from the air intake to the EGR. New air intake comes without the tube. Replace to the lower plenum bolts. All parts available from www.rockauto.com

2004 dodge durango keeps running hot..i keep adding coolant then it stop for couple of days then start running hot again


If yo keep adding then you're obviously losing antifreeze somewhere. If it's not dropping on the ground then I'd say you have a blown head gasket and it's going out the exhaust. If you keep running it hot and it is a blown head gasket, sooner or later you'll warp the head or crack it, then you'll really be outting out the money for a fix.

Having to keep putting water in car and the temperature gauge goes up and then its starts to run hot what could it be


Hey, first. the ideal coolant mixture is 50% coolant and 50% distilled water. So just adding water is not the best thing.

Second, if you have to keep adding coolant or water to your radiator, you likely have a leak. You can go to the Auto Parts Store and get some Radiator Stop Leak and pour it in there and see if that helps. You may just have a small hole somewhere.

You could also take it to a shop and tell them to check for a leak in the radiator.

My temp guage just shot up to past the H, my coolant is empty. Do I just wait for car to cool down and add water to radiator or add coolant at any time, or both?


DON'T PUT WATER IN IT HOT!!! You need to wait a few hours to add water water, the engine should be cool to the touch. Or if you can heat several gallons of water to around 170 degrees or so you could add to the system hot. This is also dangerous since that hot of water can burn you. Adding cold water to hot metal you run the risk of cracking your engine, or at least your radiator. Best of luck hope this helps.

1995 TAHOE BLOWS HOT AIR OUT THE VENTS DURING ACCELERATION


Did you mean the only time it blows hot air is under acceleration?

First thing check the coolant level in the radiator. If coolant is low the first hing to stop working is the heat.

If the coolant level is fine but the coolant is muddy I woulds suspect a plugged heater core. You can try back flushing it by removing both heater hoses (engine cold) and then use a garden hose to flush clean water through the heater core. Do this on both pipes going into the heater core. Keep flushing until the water runs clear. Re attache the the hoses, remove the radiator cap, start the engine, let the engine come up to temp and top off the radiator with straight coolant (to comp for the water in the heater core). You may have to repeat this process several times over several days but you should be able to get it cleared enough to get sufficient heat without having to replace it.

Car ran hot ...low on coolant..added to reservoir...car not running hot now but level in reservoir keeps going down...have added twice more to max line...no leak under car temp normal


Bleed your cooling system. You have a air pockets in your system. Don't forget to run your heater full blast when doing so. Usually help to unplug your heater hose and flush out the heater core then work on getting it filled and getting all the air out of your system.

OVER HEATING ISSUE!!! 2003 JEEP GRAND CHEROKEE


Since you added coolant, now it is time to check the fans. If the fans do come on, than your thermostat needs to be replaced, Should be done every 4 years anyways.

Coolant system


If your coolant level is dropping, I would suggest that you take a good look at the water pump. That is a very common coolant leakage probelm area on your vehicle. I change 2-3 a week.
Hope this helps.
