A factory plastic unit sitting directly in the coolant loop, baking through heat cycle after heat cycle.\u003c\/p\u003e\n\u003cp\u003eOver time that plastic goes brittle. It cracks at the seams, warps around the sealing surface, and starts weeping coolant right when you can least afford to lose it. A slow leak turns into a coolant warning, a coolant warning turns into an overheat, and an overheat on a turbocharged engine is not a cheap mistake.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eThe Permanent Solution:\u003c\/b\u003e We don't replace a failed plastic part with another plastic part.
