2014 LML passenger side overflow constantly full while engine side is low. Passenger side is pressurized and spews bubbles. Cooled overnight and pressure remains. new rad cap didn't help. I bring it to operating temp and on restart shows 'low coolant'.

I hate to say it but head gaskets. My truck was doing the same thing. It’s in getting done right now.

@Rotto, your silence tells me you have discovered how much it will cost for repairs. I was shocked too but more pissed off. I just bought truck back in May. All stock and only 158k kilometres on it. Lots of opinions and suggestions on here for repairs.
I personally went with ARP studs instead of head bolts even though I was keeping it stock. Three mechanics I talked to recommended them. Also recommended was a water pump change. Good luck in your repair. I should have mine back this week.

I'm not normally one to recommend replacing parts that aren't bad, but my water pump literally went bad almost the day after I finished head gaskets on my truck. At a minimum a person should replace the stud with a small allen headed bolt so it can be removed without pulling the balancer.

I don’t either but the three guys who I talked to said at this point you should. Cost of the pump is negligible considering all costs involved.
