First... I'm not a wrench . so be nice. My 2010 HEMI Ram just started this. I need direction to trouble shoot it. Its not throwing any codes. If I'm idling say at a bank or fast food drive through. About 15-20 minutes my coolant temperature starts rising. Typical its at 195 degrees but at stop its has hit 260 & my engine HOT warning at 255. If I get moving say up to 55MPH everything seems to cool down back to about 195. Any suggestions or input would be appreciated.
