Now, we move on to installing the AN fittings.
Install the -6AN ORB to -6AN flare fitting into the upper steam line port after lubing the O-ring with some motor oil. Tighten with a 3/4” wrench.
Install the -10AN ORB to -6AN flare fitting onto the radiator vent port (rectangular side) and the -10AN ORB to 1/2” nipple on the coolant return port (circular side). Tighten with a 1” wrench. Don’t’ forget to lubricate the O-rings with a bit of motor oil!
Now it’s time to remove the stock de-gas Bottle. This thing is made of plastic and has no internal baffling. Basically, it’s a milk jug.
In an attempt to keep the mess to a minimum, I first siphoned out as much coolant as I could.
After siphoning out as much coolant as possible, I clamped the radiator vent and steam lines, loosened up the stock clamps, and removed them from the bottle.
