BMW Coolant & Radiator Hoses for BMW 3 Series E90 (2006-2011)

The N54 engine, like many BMW engines, has a reputation for encountering cooling system issues. To address this, Turner Motorsport enthusiasts have curated a comprehensive kit to safeguard your N54 cooling system against potential failures.

Included in the kit:

1. Turner Motorsport Heavy Duty Aluminum Expansion Tank Kit:

Enhances the factory plastic tank design, known for its vulnerability to failure. Maintains original coolant capacity and expansion volume. Features a baffled tank design to prevent air pockets during aggressive driving. Includes a specially designed bleed passage to avoid air introduction during engine cooldown. Constructed with fully-TIG welded 5052 aluminum. Comes with aluminum bleeder screw, OE coolant level sensor, expansion tank cap, flared coolant pressure release line, and all necessary installation hardware. 2. ECS Performance Coolant Outlet Hose Kit:

4-ply reinforced silicone outlet hose. Internal layer lined with Flourosilicone for exceptional chemical resistance. Equipped with billet 6061-T6 outlet adapter. 3. Redline Water-Wetter Coolant Additive - 12 oz:

Lowers coolant temperatures by up to 30*F. Compatible with various cooling system components including aluminum, cast iron, copper, brass, and bronze. For N54 owners seeking enhanced cooling system performance and longevity, especially those pushing significant power, this kit is indispensable.

This coolant outlet hose connects the cylinder head to the thermostat housing and is a critical component of the cooling system. For many N54 owners, the "Mickey Mouse" flange is a common failure point. This plastic connector is vulnerable to degradation from heat, exposure to chemicals, and wear over time.

If your outlet hose has failed or the cylinder head flange is leaking, it’s best to replace the entire assembly for a reliable and long-lasting repair.

This Coolant Hose is located behind the thermostat on N54-equipped BMW models. Due to weak rubber construction and its close proximity to the bank one turbocharger, this hose is a common failure item on high-mileage vehicles.

Whether you are replacing a failed hose or preemptively servicing your cooling system, choose this high-quality replacement from Bremmen Parts for a lasting repair.
