Cooling System Products | BMW E39 525/528/530

In order to maintain peak engine performance and ensure engine longevity, regulating proper operating temperatures is imperative. Instead of waiting for cooling issues to erode your car's performance and damage expensive parts, replace your water pump preemptively, saving unnecessary time and expense.

ECS offers OEM BMW and aftermarket Water Pumps. Each aftermarket option features a metal impeller, and includes an alignment dowel and sealing gasket.

Commonly replaced at around 60k miles, this critical engine component is a wise investment for your E39.
