{"title":"EGR Cooler","description":"\u003ch2\u003eGenuine OEM EGR Coolers\u003c\/h2\u003e\n\u003cp\u003eA leaking or clogged EGR cooler can allow exhaust gases to mix with coolant, leading to white smoke, coolant loss, overheating, and in severe cases, catastrophic engine damage. Because the EGR cooler must lower recirculated exhaust gas temperatures before they re-enter the intake, a wrong or generic replacement with incorrect flow rates or insufficient heat exchange capacity often can't keep up under load — accelerating failure and putting the engine at risk.
