2011 Volvo D13 STOP engine fault

613005

{"text":"I have a 2011 volvo, D13 engine, I-Shift, and while pulling the trailer uphill, I keep getting the Stop Engine Fault message. Everytime I pull over, I stop the engine, pop the hood and I can see the coolant boiling but the water temperature gauge doesn't go over 200degrees. I had it in 3different Volvo dealerships, they replaced The EGR cooler, they tested the truck but didn't get any error on the computer. They also changed the thermostat. About a month ago I had the water pump replaced, the coolant tank and all the hoses and I have no leak whatsoever. Probably not related, but I also get a message on dashboard saying 'tractor front parking light open circuit' and other Check lights messages. I have no issues when bobtailing. Any ideas on what the problem might be? Thank you.","pics":"[]","canComment":true}
