I had a mechanic look at it briefly and he said that there might be a leak in a hose. He said that he doesn't feel pressure in one of the hoses. He told that the cooling fans run. I had replaced my radiator cap with one at a junkyard, but then I decided to get a brand new one today for $8 dollars. I am gonna get the car pressure tested on Monday or Tuesday to see if there's a leak. Then I'm gonna do a full coolant flush.
