If the coolant level still in low mark when engine is fully warmed then you should have it checked out.

Don't risk it, you may have a bad water pump

Check this link out, GS350 pumps go out often, so if your car has mileage its best to replace it right away.

yeah I would get it checked, you could have a bad water pump like ibidu1 said, I had the same issue but I caught it early, someone on the forum wasn't so fortunate. Yes it should be covered under your power train warranty.

That's a big air pocket.
How long ago was your cam gears replacement?

I have a heard time believing the tech didn't bleed the radiator before letting it leave. Have the pump inspected
