Hello everyone. I just bought a used 2004 Dodge Durango with the 4.7 v8 magnum and I noticed its running a little hot. Its at my local repair shop and they are going to do a system flush. I hope this solves it. I have been reading on some issues with this engine including engine sludging, I hope that is not the case. Any tips would be helpful as to fixing the slight overheating issue.

Thanks!
