Coolant boiling out

[kmac0011]

I took my 2011 1500 to run some errands yesterday and when I got home coolant started boiling out of what looked to be the overflow tank. Looked around and couldn't see any obvious issue other than I noticed the fan sounded louder than normal the next time I started my truck. Do any of y'all have any ideas what it could be?

I've had it where the thermostat failed half closed, as well as my water pump starting to fail. That may be something to check out.

could be a clogged line. also keep an eye on your trans temp.

I took it for another drive and the transmission temp is good and the temp of the engine is good until I shut the truck off then it goes up and boils over.

Electric fan or mechanical?
