My radiator gurgles
I have a 2002 dodge Durango and
the radiator started to gurgle and it
tries to over heat . I shut it off before
it got to hot . There is nothing coming
out of the exhaust so I don't know if I
can completely rule out head gasket.
But when I tried to start it back up it
shook and hesitated could this have
been because it was still hot and was
telling the sensor that ? Please help
That sounds like it has already blown a head gasket. Get a "block check" performed at a shop you trust, that will tell you what your next step is.
There are two ways that the water can go if the head gasket blows, in the exhaust like you said but the other way is into the oil, so check if the oil has a creamy color or smells of anti frees. Also check for leaks under the truck you could have a bad hose and they usually go bad where the clamp is so look at those . you could also have a water pump starting to go bad then you would get the coolant out on front of the engine and leaking down. You could also have a stuck thermostat you can take that out and put it in boiling water and if it opens, if it is open when cold it is stuck open and needs to be replaced but that would only cause the engine to warm up slower but not causing the radiator to gurgle. Always start on the cheaper things so start on the hoses. make sure you have enough coolant in it and if you need to drive it have extra coolant with you so you can top it off. make sure you don´t over heat it cause you have aluminum heads and you can kill them very easy with over heating and if you have the 4,7 l engine it is even more sensitive.
