Im changing my radiator fluid and drained it from the bottom. I got 4 gallons out of and I can only pour 2 back in. Do u know an easy way to get the air out? Thanks

 

What model and engine are we talking about? Is your heater in the heat position?

 

If it's a common rail 5.9 then remove the heater hose off of the pipe that comes out of the top left of the block towards the back of the engine. This is the highest point, (not to mention the easiest), way to bleed the air off.

 

Removed the heater hose and worked perfect.. Thanks guys
