LANDNOVO 11517632426 Electric Water Pump for BMW N54 / N55 3.0L Turbo Engines | Premium OE Replacement

LANDNOVO — Precision in Motion. Engineered by GB.

Is your BMW 135i, 335i, 535i, X5, X6, or Z4 displaying an overheating warning, coolant leak, or engine temperature fluctuation? The culprit is often a failed electric water pump. The LANDNOVO 11517632426 Electric Water Pump is a premium, direct OE-grade replacement engineered to restore your vehicle's cooling system performance and engine protection.

The LANDNOVO Difference

LANDNOVO is a premium automotive brand with a distinct British engineering heritage, crafted for discerning drivers who demand nothing but the best for their vehicles. Every LANDNOVO component is Designed by GB — a mark of British precision, quality, and durability.

This electric water pump is manufactured to the highest standards, matching the quality of the original equipment (OE 11517632426) that came factory-installed on your BMW. It is a complete drop-in replacement, designed for a straightforward installation.

Why Choose the LANDNOVO Water Pump?

The electric water pump is a critical component of your BMW's engine cooling system. Unlike traditional belt-driven pumps, the electric pump is controlled by the engine computer (DME) and operates only when needed — including after the engine has been switched off — to manage temperatures for multiple systems throughout the vehicle. However, because it is electric, when it fails it does so completely and without warning.

This LANDNOVO pump features an aluminum front cover instead of the original plastic cover, which is prone to cracking and coolant leaks. The aluminum construction offers superior durability and longevity compared to the factory plastic design. The internal pump remains fully functional, but when the plastic cover leaks, complete replacement is required.

Instead of paying dealership prices, the LANDNOVO water pump provides the same OE-level reliability at a fraction of the cost.

Symptoms of a Failing Water Pump

• Sudden failure without warning – electric pumps can fail completely and without prior indication.
• Check engine light – the dashboard displays a cooling system-related warning.
• Reduced engine performance – the engine may go into limp mode to prevent damage.

Installation Tips

• Professional installation is highly recommended for this component.
• BMW recommends replacing the water pump every 60,000 to 80,000 miles as preventative maintenance.
• When replacing the water pump, it is strongly recommended to also replace the thermostat.
• New mounting bolts are included and must be used – the original bolts are single-use and cannot be reused.
• After installation, perform the BMW cooling system bleed procedure: turn ignition on (do not start engine), set heater to maximum, press accelerator pedal for 10 seconds, and allow the 12-minute self-bleeding cycle to complete.
• Use only the correct BMW-approved coolant mixture.
