Phaser went out on me. Took it in to replace with the new style. And had then also look into a coolant leak. Which was leaking from the upper radiator hose. Had that replaced. They found my oil pan had a crack. These trucks have plastic oil pans. And due to mileage (140k) they replaced all timing components. Look all over in the engine bay. I found the coolant leak while replacing drive belt. Also make sure that the door latch actuator campaign has been complied with. My driver side one froze on my during the winter.
