That's my plan and has been for 7-8 years but the damned copper OEM radiator
just won't die!.

Those plastic bottles use a plastic cap that serves as the radiator cap as
well with pressure regulation and backflow relief just like a normal
radiator cap. After a while, the plastic shell starts to degrade and
cracks. One fell completely apart on me. My fallback is fab a metal cap
that will accept a standard radiator cap. After 22 years, you sometimes
have to get creative with parts....
