Let me try and clarify a little better. The small coolant hose I am reffering to comes off one side of the metal tube and goes to the thermostat. The other end of the metal tube also has a hose that the coolant runs thru. Basically it all the same line but I just want to remove the metal tube inbetween the 2 hoses and just make it one hose and remove the metal tubing all together. I just wasnt sure it it will hurt anything or if that metal tube is there for a purpose before I remove it.
