BMW M5x/S5x ECS Water Pump Pulley and Pumps
When it comes to vehicles that are already plagued by cooling system issues the water pump is one of the last components you want to fail.
If you are looking for performance then the Stewart water pump is the way to go, hands down. This is without question a BMW favorite.
Finishing off the task with an ECS aluminum pulley not only adds a bit of efficiency, but strength so you no longer have to worry about how long the composite pulley will last. The added bonus is, it's another small touch to a clean engine bay.
