BMW Cooling System Parts & Accessories for BMW 3 Series E92 (2007-2013)

Clear BMW chassis

Please ensure your correct model is selected

The cooling system is arguably the weakest point in numerous BMWs. If you drive an aging BMW or plan on taking your car to the track like we do, we recommend beefing up your cooling system before going to the track. Generally, the main components in your cooling system that are prone to failure include the following: expansion tank, factory hoses, water pump, thermostat, fan (especially if your vehicle comes factory with a clutch fan), and radiator. Factory BMW expansion tanks are plastic and prone to either breaking off at connection points or combusting. As factory rubber hoses age they either crack or break over time - we offer silicone cooling hose upgrades for most applications to avoid future failures. If you have an older vehicle, your water pump likely comes from the factory with a plastic impeller - we offer upgraded water pumps with metal impellers that are far more reliable. Newer model BMWs utilize electric water pumps - BMW spent millions of dollars engineering these water pumps, but they fail so often that we recommend replacing at 60,000 mile service intervals to avoid being stranded on the side of the road. In terms of thermostats, we offer various upgraded thermostats for racing applications. If your BMW utilizes a clutch fan from the factory, we have several options available in terms of universal electric fans - we recommend replacing these to avoid sending brittle plastic fan blades through your hood. For radiators, we recommend swapping out your radiator for one that does not use plastic connection points like your factory radiator.

Using 100% SuperCool Performance protects the entire cooling system, keeping new components like new for 5 years/150,000 miles and prevents further damage to older components. Red Line’s proprietary coolant additive formula enhances the fluid’s ability to transfer heat, reducing operating temperatures by up to 20*F and prolonging the life of the entire cooling system. Red Line's SuperCool is an OAT coolant that is a Nitrate and Silicate Free product with its own proprietary corrosion technology to offer superior protection for aluminum engines found in all European vehicles, performance vehicles, as well as other applications. SuperCool will not void the factory warranty either. It can be used to top off the existing coolant of any BMW and will not cause any ill-effects on the cooling system because it is silicate and nitrate free. It is still better to flush it out and switch completely to SuperCool to get all the full benefits of the product in performance and protection.

The thermostat regulates the temperature of your coolant. At a predetermined temperature the thermostat will open to let coolant flow to the radiator and be cooled by airflow or the fan. Over time the thermostat will become stuck open or closed, leading to a variety of issues. A closed thermostat will never allow the coolant to reach the radiator and be cooled. Hot coolant will continue to circulate through the engine and absorb even more heat until boiling and the system overheats. An open thermostat is not as bad but is still not ideal - the coolant is always cool, with the temp needle always reading in the cool range. This tells the ECU to richen the fuel mixture to bring the car up to normal operating temp. So your fuel mileage decreases and the car runs rich.   

Replacing the thermostat is an easy but messy job. This thermostat includes the main o-ring (but a housing gasket may be required). Consider replacing the housing and any associated temp sensors while you're in there. The cooling system will need to be bled after.  

For vehicles with plastic thermostat housing

The coolant expansion tank in your vehicle gives additional fluid a place to go after expansion and contraction from temperature change. Because it is subjected to such drastic changes on a regular basis, it can often crack or break. You want to keep all the coolant in your vehicle in the cooling system. If your tank has experienced damage such as cracking, nipples breaking off, or mounting point damage, you will need to replace it.

As most 335 owners have discovered, the cooling system is vital to maintaining high levels of boost. The car's sophisticated electronics wisely shut down and limit boost when temperatures are elevated enough to do potential harm. Don't short-change your cooling system or performance on the street or the track! Where the stock radiator suffers is in capacity, which is why BMW also sells an additional radiator and other cooling upgrades with their Performance packages. This radiator for the E90/E92 335 and E82 135/1M is a larger 40mm core (2mm thicker than stock) for additional capacity and bulletproof cooling. It fits in the stock location, with the stock shroud and fan (some plastic trimming may be necessary), maximizing the available space to dedicate to fluid capacity and surface area. Having a greater capacity means less saturation time for the cooling fluid which leads to more consistent engine temperatures, reducing the possibility of limp mode condition and reducing wear and tear on other cooling components such as the water pump and thermostat. If you're looking for the most complete and unbeatable radiator solution for your E9X, this is the best we have seen. Not only is this radiator larger, but it's also designed with the stresses of motorsports in mind. The cooling vanes use a unique oven-brazed bonding technology that will not fatigue and crack like epoxyed construction. Aircraft-grade aluminum is used for the tanks and frame, which are TIG-welded for superior strength. This radiator is a direct replacement for the stock E9X radiator, with all of the same hose locations and fittings as the original radiator. Because of the extra depth required between the radiator and engine, extra care will be needed when installed with upgraded intercoolers, intake piping, and oil coolers. This aluminum radiator is a replacement for the stock BMW radiator 17 11 7 558 480 and fits the 135i and 335i/xi (automatic transmission only). This item fits the following BMWs: 2008-2012 E82 BMW 135i 1M Coupe - with auto transmission only 2006-2011 E90 BMW 335i 335xi 335i xDrive - Sedan - with auto transmission only 2007-2013 E92 BMW 335i 335is 335xi 335i xDrive - Coupe - with auto transmission only 2007-2013 E93 BMW 335i - Convertible - with auto transmission only 2009+ Z4 BMW Z4 28i Z4 35i WARNING!

Ensure the longevity and safety of your vehicle's engine by replacing aging plastic and rubber cooling system components.

Eventually, you are going to replace the radiator in your vehicle. The joints where the cores meet the end tanks tend to get weak, crack or split and cause a leak. Impacts to the fins can cause cracks and punctures. Corrosion and clogging from the inside can make cooling less than effective and compromise coolant flow. Replacing your leaking unit with a genuine BMW OEM replacement restores flow and prevents overheating.

Just like the rest of your vehicle's major systems, the cooling system must also be addressed periodically to ensure proper cooling and component reliability. Plastic and rubber components become brittle and prone to splitting or cracking after long periods of heating and cooling cycles, especially in colder climates! The coolant itself can degrade or become contaminated, leading to potential corrosion or freezing issues. Finally, thermostats and sensors can fail completely, preventing proper cooling and/or coolant temperature readings to become inaccurate.

To make sure you are not left stranded on the side of the road with an overheated engine, we have put together this Basic Cooling System Service kit. This kit contains all of the most-likely-to-fail components, giving you peace of mind knowing your engine will continue to run cool for another 60,000+ miles.

See kit contents below for all included components.

Engine running a little hot or is the temp gauge not telling you anything? The thermostat might be the likely problem. Many cooling issues start with the thermostat. This is electronically controlled by the engine computer based on the cooling demands from the engine. And cooling components are working harder than ever. Engine performance is also dependent on temperature - as temperatures rise and pass a certain threshold the engine computer will begin reducing power. Stay on top of your cooling maintenance by replacing critical components preventatively. This replacement thermostat fits many of the N55 6 cylinder engines and is an Wahler part. The thermostat is located along with the water pump on the side of the engine. To gain access for removal you may need to remove the water pump as well. If the water pump is removed you MUST replace its mounting bolts. You can add them from the options below. We also have a bundled package that includes the water pump, mounting screws, connecting hose, and clamps if you want to replace everything together (recommended).

When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.

2008-2013  E82 BMW  135i 135is 1M Coupe

As most 335 owners have discovered, the cooling system is vital to maintaining high levels of boost. The car's sophisticated electronics wisely shut down and limit boost when temperatures are elevated enough to do potential harm. Don't short-change your cooling system or performance on the street or the track! Where the stock radiator suffers is in capacity, which is why BMW also sells an additional radiator and other cooling upgrades with their Performance packages. This radiator for the E90/E92 335 and E82 135/1M is a larger 40mm core (2mm thicker than stock) for additional capacity and bulletproof cooling. It fits in the stock location, with the stock shroud and fan (some plastic trimming may be necessary), maximizing the available space to dedicate to fluid capacity and surface area. Having a greater capacity means less saturation time for the cooling fluid which leads to more consistent engine temperatures, reducing the possibility of limp mode condition and reducing wear and tear on other cooling components such as the water pump and thermostat. If you're looking for the most complete and unbeatable radiator solution for your E9X, this is the best we have seen. Not only is this radiator larger, it's designed with the stresses of motorsports in mind. The cooling vanes use a unique oven brazed bonding technology that will not fatigue and crack like epoxyed construction. Aircraft-grade aluminum is used for the tanks and frame, which are TIG-welded for superior strength.This radiator is a direct replacement for the stock E9X radiator, with all of the same hose locations and fittings as the original radiator. Because of the extra depth required between the radiator and engine, extra care will be needed when installed with non-stock intercooler and intake piping and oil coolers. This aluminum radiator is a replacement for the stock BMW radiator 17 11 7 558 480 and fits the 135i and 335i/xi (manual transmission only). This item fits the following BMWs: 2008-2012 E82 BMW 135i 1M Coupe - with manual transmission only 2006-2011 E90 BMW 335i 335xi 335i xDrive - Sedan - with manual transmission only 2007-2013 E92 BMW 335i 335is 335xi 335i xDrive - Coupe - with manual transmission only 2007-2013 E93 BMW 335i - Convertible - with manual transmission only 2009+ Z4 BMW Z4 28i Z4 35i WARNING! Prop 65 may apply to this product. Proposition 65 (Safe Drinking Water and Toxic Enforcement Act of 1968) is a California law that applies to call companies selling products in California.

The perfect upgrade for your connection between your thermostat and cylinder head. Designed using durable silicone and billet aluminum to greatly outlast the OE rubber and plastic combination.

Some of the weakest point of the cooling systems in BMW's can come down to the OE plastic fittings breaking down from the constant changes in temperature softening these plastic 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 stand up to the wear and tear of a daily driver.

Features: 

  • Manufactured from billet 6061-T6 with type III anodize for exceptional durability and corrosion resistance.

    • Much stronger part than OEM plastic

    • Will not become brittle and fatigue over time due thermal cycling.  This will prevent the part from breaking during removal and re-installation.

  • Constructed of 4-Ply reinforced silicone for improved durability over the failure prone OE rubber hose.
  • Flourosilicone 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.
