2003 caravan 3.3L blew a fairly new radiator.
I was on a highway at 70mph when my radiator blew out top right side. I have 196,000 on it and i checked oil fo coolant...none. Smelled radiator no oil smell. Mechanic is looking at it but said it could have pressure build up from a bad head gasket. My temp was right where it should have been, wasn't running hot at all when it just blew out. Radiator was installed by local mechanic 6 months ago and has a warranty.
Any clues what I am looking at?
