I servicing my cooling system and installing a new thermostat. I noticed that my radiator cap is starting to leak and the rubber in it is starting to crack up. Its a Ford radiator cap 16lb. But NAPA says I should have a 13lb cap. which is the right cap for the IDI? Also can I trust an aftermarket cap? or should I go to Ford to get it?
