Hello all, have an issue with my trucks cooling system.
It's a 2013 Cascadia DD15.
Last 8 of VIN: DSBZ6783
It looks like a pressure buildup in the cooling system. From the moment I start it up there is a lot coolant rushing in from the egr valve into the reservoir.
With the old radiator cap on, coolant will gradually overflow the tank and leak out the top.
I replaced the cap with a new one and the level stays even in the tank, however hoses are starting to bust when the new cap is on.
In the lead up to this, I've had the egr cooler replaced and had blown head gasket. Did an inframe, the pressure issue persists.
Using an exhaust gas test kit, it doesn't look like any gases are getting into the coolant.
At this point I'm tapped out and am having to wait on going back to a mechanic. Just trying to get some ideas to look at.
Any suggestions would be appreciated.
