Radiator cracked

[Nobody]

Hi guys, was not here for a while busy with my other project - Porsche 928 GT. I was using my SVX extensively for couple months and now during check I spotted cracks on upper side of radiator. Why the hell they did it from plastic??? So upper plastic part has several cracks which are bleeding with AF fluid. Seems to me it is integral part with whole radiator. Is there any fix of it? Can be replaced only upper part or whole radiator? Thanx for any EU advice, do not plan to buy this unit in the states. It is pretty urgent as now unfortunately have to rely on SVX:-(.
Thanx a lot, Petr
