why would i still have pressure on my radiator cap after the car has not been run in approx 2 days. it is a show car and does not get driven on a daily basis. the other day i went to check fluid level in radiator and when i released the cap it pushed out anti-freeze although not hot obvisously. it has a new cap.

I would say that the new cap is faulty, take it to a radiator shop or work shop and get it tested, try this first as there is nothing that would keep pressure up in the system with a cold engine.

it also can be the wrong cap. It may be a cap for a closed system and you are runing one without, or it's the other way around.
