Performance Water Pump & Thermostat Kit | ES4818358

As a common failure point amongst all BMW models, the water pump should be serviced every 60,000 miles. While doing so, it is good to change the thermostat to ensure proper functionality of your vehicle's cooling system. Thankfully, ECS has combined these parts in one simple kit to make your cooling system refresh even easier. 

To maximize the effectiveness of this service, our kit is based around the famous EMP Stewart high-performance water pump. Well-known by many BMW enthusiasts, this water pump features a redesigned stainless steel impeller boasting a 20% increase in coolant flow. Paired with a low-temperature 68*C (154.4*F) Mishimoto thermostat, upgraded aluminum thermostat housing, and Redline Water Wetter coolant additive, this kit is truly the ultimate upgrade for your M5x/S5x-equipped BMW!
