BMW Cooling System Parts & Accessories for BMW 4 Series F32 (2014+)

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.

Replace your fragile OEM plastic coolant bleeder screw, which is prone to cracking and failure, with a premium titanium upgrade built for strength and style under the hood. Factory plastic components weaken over time due to constant heat cycles, leading to brittleness and potential failure. Our titanium replacement delivers superior durability, being twice as strong as aluminum yet 45% lighter than steel, ensuring unmatched resilience and long-term reliability for your coolant system. More than an upgrade, it’s a must-have for engine longevity. CNC-machined from solid titanium, each screw features a laser-etched Burger Motorsports logo and is hand-burned to create unique color patterns—no two are alike. A heavy-duty replacement O-ring is included for a perfect fit.

The water pump in your vehicle keeps all that coolant flowing freely. If it begins to fail, overheating problems are inevitable. Don't take a chance on doing damage to engine internals by not replacing your water pump. This has been a common problem amongst most German vehicles. Water Pump failure can lead to your vehicle making an unnecessary trip to the repair shop. If your pump stops working, coolant temperatures rise rapidly and can overheat the engine, leading to head gasket or even piston ring failure. This is a great preventative maintenance item when doing any type of timing belt replacement. This is a common replacement around 80,000-100,000 miles.

The Coolant Outlet Connector connects the engine block coolant outlet to the upper radiator hose.

Due to fragile plastic construction and consistent exposure to hot, chemical-rich engine coolant, this piece is prone to degradation and (potentially) complete failure.

Whether you're fixing a failed connector or preemptively replacing this failure-prone component, choose this quality replacement from Bremmen Parts for a lasting repair.

This is the high quality Pierburg electric water pump for F30 F32 F22 models with the N55 6 cylinder turbo engine. The electric water pumps on older N54 and N55 engines tended to be failure prone. The N55 water pump is electrically driven and varies output based on instructions from the engine computer. Under the best circumstances the pump drives only as much coolant as needed and will shut down or activate as load and performance demands change (combustion chamber temperatures are dynamically changed based on economy, normal, and performance demands). The pump can also run when the car is off to reduce heat soak in the engine and turbo(s). The water pump is now a factor in how much power and fuel economy your car is producing, making it all the more critical to replace during normal maintenance. If a fault or excessive temperature is reached, the dash cluster will display a yellow or red water temp icon depending on the severity of the condition. The car's electronics will begin shutting down various systems in the car to divert more resources to the cooling system. This can include reducing power output and activating 'limp mode'. The best way to avoid problems and system failures? Preventative maintenance and overhaul of the cooling system, starting with the water pump (and thermostat). NOTE: ONLY for cars with M Sports Package - option code P337A This item fits the following BMWs: 2012+ F30 BMW 335i 335i xDrive - Sedan 2013+ F32 BMW 435i 435i xDrive - Coupe 2013+ F33 BMW 435i Convertible 435i xDrive Convertible- Convertible 2014+ F34 BMW 335i xDrive GT - Gran Tourismo 2014+ F36 BMW 435i Gran Coupe 435i xDrive Gran Coupe

When it comes to your temperature gauge on your instrument cluster your thermostat plays a large role in where that temperature needle ends up. There are many cases where the vehicle will run a bit cool according to that gauge, oftentimes meaning the thermostat has failed and is stuck open allowing coolant to continuously circulate. The other more damaging side is when it closes shut and keeps the engine from cooling down properly. All vehicles are designed to operate in an ideal temperature range for the ultimate efficiency, life, and performance.
