Decades of under-hood radiant heat soak cause the molded polypropylene to turn yellow, micro-craze, and embrittle. Structural failure occurs along the molded ultrasonic mid-seams, around the lower outlet hose barb, and across the mounting ear bosses. Under heavy towing conditions, these stress fractures burst, causing rapid pressure loss, boiling over, and cooling system cavitation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a permanent mechanical fix, this tank is fabricated from high-grade sheet aluminum and fully TIG-welded to eliminate vulnerable molded seam points. Aluminum delivers superior heat dissipation and impervious structural integrity against cyclic internal pressure spikes and UV degradation. The reservoir features precision CNC-machined barbed ports and a reinforced filler neck engineered to maintain a hermetic seal with the included pressure cap.
