All OEM connections, the stock cap, and the factory coolant sensor are fully retained for a seamless, plug-and-play installation with no warning lights or level reading issues.\u003c\/p\u003e\n\u003c!-- Why Upgrade --\u003e\n\u003cdiv class=\"wce-why\"\u003e\n\u003cp class=\"wce-why-label\"\u003eWhy upgrade?\u003c\/p\u003e\n\u003cp class=\"wce-why-text\"\u003eThe factory plastic reservoir is known to crack and leak coolant directly onto the injectors and ignition coils — causing vehicle downtime and potential engine damage.
