The N20/n26 engined cars already suffer from reduced cooling area because of the factory intercooler, tight space under the hood, and of course heat from the turbo(s). BMW addressed these challenges a number of ways, including a dynamic, 'smart' electric water pump with increased output compared to normally aspirated models. The cooling demands mean additional stress on the major cooling components, especially the water pump and thermostat.

If your vehicle is experiencing cooling issues, chances are the thermostat is the cause. Common symptoms include prolonged warm-up at highway speeds from the thermostat being stuck open, or consistent overheating issues from the thermostat being stuck in the closed position. Either condition can result in poor performance, and potential damage to vital components in your vehicle.

Replace the flimsy plastic bleeder screw used in the coolant expansion tank or in one of the cooling system hoses with this high quality, durable, aluminum bleeder screw. The stock plastic screw can deform over time due to heat or even regular use. We have even seen the head of the screw snap off, leaving the threaded body stuck in the expansion tank. This aluminum screw will help to prevent sudden failure of the bleeder screw, which can result in immediate overheating of the car.

Why not upgrade when you're due for a replacement? The ECS Tuning silicone hose replacement fixes these issue with two key features in their design. Offering this hose in a much more heat resistant silicone instead of OE rubber and having the hose wrapped in aluminum. The aluminum coating acts as a heat shield to further protect the silicone as well as reducing the temperatures forced on the coolant running through the hose.

The perfect upgrade for the connection between your thermostat and cylinder head. Designed with durable silicone and billet aluminum to greatly outlast the OE rubber-and-plastic combination.
Some of the weakest points in BMW cooling systems can be the OE plastic fittings, which break down from constant temperature changes, softening these components. When this happens, even simply moving the hose slightly could cause the fitting to crack, causing the coolant to leak all over. The ECS design silicone hose with billet aluminum adapter retains OE fitment with superior strength to not only handle the performance, but also stand up to the wear and tear of a daily driver.
Features:
Manufactured from billet 6061-T6 and type III anodized for exceptional durability and corrosion resistance.
Much stronger part than OEM plastic
Will not become brittle and fatigue over time due to thermal cycling. This will prevent the part from breaking during removal and reinstallation.
Constructed of 4-ply reinforced silicone for improved durability over the failure-prone OE rubber hose. Fluorosilicone-lined internal layer for exceptional chemical resistance. Silicone offers reduced thermal conductivity as well as improved resistance to ozone and UV degradation for improved performance and durability. Follows OEM form for perfect fitment. Utilizes OEM O-ring 11537545278 to ensure a proper seal. Replaces Genuine BMW Part Number: 11537584549
