I was looking at why my car is over heating. And i turned it on drove it around and got it to get normal temps. Then i was looking at the top radiator hose and never once did it have pressure, i was holding it down with my hand with some gloves. You could fell the water pass tru, but it never held pressure. Its suppose to have pressure sometimes right to let it cool down in the radiator??? The t stat has bout 1000 miles on it. So i dont think its that. Honesstly i have no idea???? What do u guys think????
