I had similar problem on 600. The reason is chemical bond between steel screws and aliminium radiator.
On 600 the screws are allen key. If that is the case you can use slightly bigger size torx.
I have used T27 Torx and a hammer to tap it in and a lot of penetration fluid.
Then you carefuly tighten slightly to break the bond. Then untighten. Again thighten. After it breaks you can go.
