If your thermostat and pump are functioning properly, they're fine to reuse. However, this is a good time to inspect both—if they're original or have high mileage, replacing them at the same time prevents a comeback job.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp\u003e\u003cstrong\u003eWill I need to flush the cooling system before installation?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. Drain the old coolant completely and flush the block and hoses with distilled water before installing this radiator.
