Was draining the radiator yesterday, running some new engine ice formula through it. I filled radiator, and proceeded to remove coolant reservoir bottle, pulled it off, and filled with engine ice to full mark as well. Now, there are two hoses on this bottle. One at the bottom with a clamp, and one at the top with a clamp. Well, after I'd re-installed the bottle, I noticed the top hose was connected to the bottle, but nothing else. It also has a sharp point at the end of the top hose, that makes it look like a breather hose or something. My question is, does this top hose run to anything, or just sort of free lance loose? I looked at the service manual pg.68, but the drawing isn't clear, and neither is the wording on routing imo. Does anyone know? My bottom hose is intact. Thanks in advance. If anyone could just glance at theres, I'm sure it would help.
