One of distinctive features of Phobya G-Changer radiators is presence of four inputs/outputs instead of regular two. This allows tube routing to be more conveniently arranged. Unused ports are sealed with special leak-proof plugs that come with the rad.

Phobya G-Changer 420 safety feature

Side tubes of radiator has small bars soldered to prevent them(tubes) from being punctured when using fan mounting screws of extra length. The last is said to be the most common mistake when WC system assembling, especially for beginners.

The bottom tank has a special screw for bleeding air bubbles out of rad. There is a spare bleed screw in the package in case you lose it.

Overall impression of radiator outlook and accompanying accessories is positive.
