I have a 2008 6.4 that caem in blowing coolant out the degas bottle.
First off the cap was bad. so new cap
But I put a gauge on the system and it runs up to 19 psi going down the road and builds pressure to 15 even before the engine is very warm.
Also there is a constant stream of bubbles coming out the Rad and EGR cooler bleed hose on an idle.
Is that normal?
