Thanks for the help. I noticed a hose thats not connected on the top of the big hose that connects from the Radiator to the back of the engine where the thermostat is. The hose is being held in place but the end is just open. There is nothing connecting to it. Could someone tell me what this hose might be for. Its right on top of the hose that connects to the thermostat. I have looked in the book and can't find it anywhere. Is is connected somewhere on one end but the other end is just open. By the way I have a 1998 Accord Coupe 4Cyl. if that helps.
