I have a 2000 Dodge Durango 4.7L V8 SLT.

Just recently, the top radiator hose was torn in half (no idea how that occured.) I discovered this on the ride home when white smoke was pouring into the SUV and out of the hood. After dumping some coolant into the radiator, I finally got it to Autozone and replaced that hose. Before this, I knew it had a very small leak, so I wasn't too worried about it.

After replacing the hose, the coolant is no longer leaking out, but the engine is still overheating as if it isn't getting any coolant. It over heats after maybe 10 minutes of driving from a cold start. I noticed that the reservoir is slightly overfull.

Shouldn't the overfill tank rush into the engine to keep it cool, or am I not understanding how that system works? If any more details are needed, I will provide as many as I can.

Thanks for the assistance.

 

your not understanding how the s ystem works

as the fluid heats up it expands, this causes the overflow tank to fill up, as the engine cools the coolant is sucked back in to prevent air from getting in. when your system emptied itself you got air in the system, if you neglected to burp the system (get the air out) then you have an air bubble causing you problems.

 

X2 all she needs is a little burping!

x3 The 3.7 , 4.7 and the 5.7 engines need a little time to bleed the air out of the system. Or they will overheat and start blowing hoses off or radiator tanks.

 

Thank you everyone! I burped the system, and now it seems to be running fine again. Y'all have been a great help!
