ECS Aluminized Silicone Water Pump Hose V2.0

Heat-shielded coolant link for N52, N54 and N55 engines, Version 2 update for easier fitment

Stop repeat coolant leaks and replace the short pump-to-thermostat link on your BMW with this ECS Version 2 upgraded hose. Built from high-quality silicone with a reflective aluminium outer layer, this compact U-hose is designed to handle the radiant temperatures found beside turbo downpipes and exhaust components, giving you reliable cooling and long service life.

Updated in 2021 for a smoother installation, this V2 design keeps the tight factory routing without kinks, improves access during fitting, and provides improved thermal protection compared to the OE rubber piece and the small factory shield. Ideal preventative maintenance on both stock and tuned cars.

Why enthusiasts choose this upgrade

• Silicone construction with aluminium heat-reflective wrap for superior resistance to under‑bonnet temperatures
• Direct replacement for the short pump to stat connector that commonly perishes, splits and seeps
• Version 2 revision for easier install, keeping the tight bends that the bay requires
• Helps stabilise coolant temperatures in high heat zones next to turbo downpipes
• Perfect reliability upgrade during cooling system refreshes and performance builds

Great for maintenance and upgrades

This is the ideal time to renew the electric pump and thermostat assembly if you are due, typically every 60,000 to 80,000 miles, ensuring your entire cooling circuit is refreshed in one go.

We have fitted these at MJ Modifications and customer feedback has been excellent, with clean fitment and a noticeable improvement in durability versus the OE rubber connector.
