Water pump question
Ok here we go. This spins off my previous post. Truck cold took off degas cap, both small cooling lines and started truck. No coolant flow at all. Did the same on my truck and it sprayed out the line coming from intake. No bubbles in tank at all.
No pressure equals bad water pump?

You should have flow from the small hose that connects to the degas bottle from the intake.
It could be a bad water pump, or it could be something in the rebuild that you did that is blocking the coolant flow.
What EGR delete did you use and can you tell us a little about the oil cooler job?

I installed the sinister kit. Not my first time it's the fourth one I have done pretty simple. From what I have read hot or cold I should have water pressure to the heater control valve.
I tapped into that line for the coolant filter kit from sinister. I also have zero flow through the kit. In my mind those are two separate jacket ways with one common.
Being aircraft and auto maintenance my whole life I am very meticulous about double checking as I work. No doubts in my mind there are no obstructions
