Title: FE expansion tank question
Post by: Saltshaker on August 10, 2018, 12:23:30 PM

Days after I drive my car if I start to take the radiator cap off the tank still has pressure in it. Is this normal?

Jon, pressure is only relieved when it exceeds the pressure rating of the cap, anything under that remains in the system.

That is a good sign you have no leaks.
