BMW Cooling System Parts & Accessories for BMW 3 Series G20 (2019+)

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.

Red Line SuperCool Concentrate fortified with WaterWetter is a concentrated antifreeze/coolant designed to maximize the performance of your cooling system with superior protection against cavitation corrosion/erosion. Using SuperCool Concentrate diluted with distilled water 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.

When it comes to serious performance driving, the stock BMW G2X radiator quickly shows its limits. Like many factory BMW cooling systems, it relies on molded plastic end tanks that are notorious for cracking and leaking over time. Additionally, its single-row, 34mm-thick core offers poor cooling capacity for high-horsepower or track-driven cars.

To address these shortcomings, ECS developed the ultimate cooling solution for the G2X B58 platform—a High-Performance Aluminum Radiator designed, engineered, and tested by their in-house BMW specialists. Built to handle the increased thermal demands of high-horsepower builds and extended track sessions, this radiator delivers both unmatched durability and significantly improved heat dissipation.

Each unit features fully TIG-welded 6061-T6 aluminum end tanks, eliminating the weak points found in the OE design. Precision CNC-machined hose connections, flanges, and mounting brackets ensure a perfect drop-in fit with factory hoses, the fan shroud, and auxiliary components. No modifications required — just direct performance.

At the heart of the design lies a dual-row, 42mm-thick core, increasing total coolant volume and surface area for improved heat transfer. Compared to the factory’s 34mm single-row core, this upgrade translates to cooler operating temperatures and consistent performance under demanding conditions.

Features:

Full 6061-T6 aluminum construction eliminates plastic end tank failures Dual-row, 42mm performance core (45% thicker than OE) for increased cooling efficiency OE Radiator: Single-row, 34mm core ECS High Performance Aluminum Radiator: Dual-row, 42mm core TIG-welded aluminum end tanks for maximum strength and longevity Polished finish for a premium appearance CNC-machined fittings and brackets ensure seamless compatibility with factory hoses, transmission cooler lines, and condenser Direct-fit installation – no cutting or modifications required Replaces OEM Part Numbers: 17118666740, 17115A30677

Engine oil coolers help reduce the oil temperature, preventing the oil from breaking down prematurely and losing its lubricating properties. Engine oil coolers play a crucial role in regulating oil temperature, ensuring proper lubrication, and optimizing engine performance and longevity. Engine oil that is too hot drops in viscosity and does not provide adequate lubrication to sensitive engine components such as bearings, which can fail catastrophically if not properly lubricated. If your engine oil cooler has been damaged or has failed we recommend replacing it to ensure no damage occurs to your engine.

Maximize cooling efficiency and take your BMW’s performance to the next level with the ECS High Performance Cooling System Bundle—a complete, track-proven upgrade engineered to handle the extreme thermal demands of the G2X B58 platform. Developed by the enthusiasts at ECS Tuning, this system includes both the High Performance Aluminum Radiator and High Performance Aluminum Heat Exchanger, designed to deliver consistent, reliable temperature control in even the most demanding driving conditions.

The factory BMW cooling components just aren’t built for high-performance or track use. Both the OE radiator and heat exchanger feature weak plastic end tanks and undersized single-row cores—common failure points when exposed to elevated heat and pressure. ECS set out to solve these shortcomings with an all-aluminum, dual-row system designed for enthusiasts who demand more from their BMW. ECS engineers started by replacing the fragile plastic end tanks with TIG-welded 6061-T6 aluminum for unmatched durability. Each tank is precision-crafted with CNC-machined billet aluminum hose connections, flanges, and brackets, ensuring direct OE-style fitment with the factory hoses, fan shroud, and accessories—no cutting or modifications required.

Both the radiator and heat exchanger feature high-capacity, dual-row 42mm cores, a massive improvement over the factory’s 34mm and 25mm single-row designs. The result? Faster heat dissipation, lower intake air temperatures, and more consistent performance, whether you’re cruising or carving apexes.

Radiator: Replaces OEM part numbers 17118666740 and 17115A30677

Heat Exchanger: Replaces OEM part numbers 17118666811 and 17115A54040

Features:

6061-T6 aluminum construction eliminates weak plastic end tanks Dual-row core design for increased cooling capacity and efficiency Radiator: 42mm dual-row core (45% thicker than OE 34mm core) Heat Exchanger: 42mm dual-row core (72% thicker than OE 25mm core) TIG-welded end tanks for superior strength and reliability Polished aluminum finish for a premium, high-performance look CNC-machined connectors and brackets for perfect OE fitment Fully compatible with factory hoses, fan shroud, condenser, and intercooler Direct bolt-in installation—no modifications required
