Why does my Subaru radiator keep overheating?
There may be a problem (warp, a crack which opens in the neck) where the radiator cap seal sits against the opening of the radiator. Also, when a radiator is pressure tested, it’s usually only luke warm, by then. IF there is any crack which opens, it could be opening only when the parts are hot.

How is a compression test done on a Subaru?
A cooling system PRESSURE TEST is performed by pressurizing the radiator by using a pump inserted in the top opening.

A compression test is used to determine how healthy the actual engine is.
