Continuous heat expansion causes internal tube-to-header weld cracking within the factory heat exchanger. Once cracked, pressurized coolant enters the exhaust stream, manifesting as excessive white exhaust smoke, rapid coolant loss without external puddling, elevated cylinder head temperatures, and diagnostic trouble codes such as low EGR flow or cooling system performance faults.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to replace OEM part numbers \u003cstrong\u003e1871733C92\u003c\/strong\u003e and \u003cstrong\u003e1871733C93\u003c\/strong\u003e, this direct-replacement assembly is constructed from high-grade, thick-wall stainless steel.
