Im not known for my description abilities. Thats just what I do and havent had a problem yet.just empty the system......then fill it..until is "full"...then run the truck...with the cap off....and its gona go down..then fill and fill until you cant no more .....:rofl:
Great point, since you have an open system you need to use the above method.Jabo the above suggestions work great if you have converted to an open system but if you still have the football on the passenger side firewall then you have the closed system and the best method is to park it with the rear higher than the front. Use ramps if you don't have a hill. remove the temp sensor on the rear of the head on the drivers side and fill the system slowly. That sensor hole is now the high spot and the air will eventually start flowing from it. you now have a system that is full and you can re-install the sensor and hook the wire back up.
