Question Running hot & losing water/coolant

Over holiday truck started running hot after about hour on road. I added water to get to destination with no further issue. Problem continued on return trip. Water/coolant level continues to drop with no leak indicated under vehicle. Where is the fluid going??
Anyone with idea or have had similar occurance please advis!

Do you have any monitoring gauges?
Are you blowing any white smoke out of exhaust?
How about the coolant tank is it venting at all?

Factory gauges are just about useless. Remove your EGR valve and look to see if valve is wet or the intake hole is wet inside. You can park the truck so the nose is lower than the rear or put rear up high with jack stands, this will allow coolant to flow toward the front of the intake if the EGR cooler has failed.

You really should have a aftermarket monitor solution.

Things to consider about owning a 6.0L

Check your ECT/EOT delta, you may have to replace the oil cooler also.
