Paccar MX 13 antifreeze leak

Have you replaced the sensor on the coolant reservoir?

 

Tank is fine. Tank has too much pressure in it and pushing coolant out of over flow side.

 

I have a coolant leak in the same area. Can some one tell me how to remove the lines that go from the distribution block down to the EGR valve.

 

The coolant tubes are o ring sealed to the junction and valve. You have the retainer off. Pliers or vice grips to turn the lines and pull out. Take your VIN to the dealer, updated Valve PN and lines are common , but need to check by VIN.

 

thank you for the assistance. I was able to get the top part of the hose out. Still working on trying to get the valve side of the hose out. Any ideas?
