2014 Sentra. 92k miles. it loses about 1" of coolant per month. no visible leaks (I used UV dye), pressure tested system (cold, obviously) and just had a UOA done with no evidence of coolant in the oil.
since it has a warranty, I have an appt at the dealer. they are claiming that they just want to do a coolant flush/fill (for a million dollars) and that they will test the system as part of that.
I expect they will claim all is good and I don't have a problem.
I also expect it's a head gasket issue that only exists when the engine is warm, but cant prove it. there is no bubbling in the radiator when running.
thoughts?
(we've had the car since new; it's never been overheated; actually it's had zero issues except repeat issues with the CVT)
