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.

The Precision Raceworks Billet Coolant Cap Set is a functional and stunningly stylish way to add a nice touch to any engine bay! These caps come in three color options, so there is always a color that will work for you! Black with Billet Silver, Black with Blue, and the Stealth series (all black). Many people don't realize it, but the OEM caps have a pressure release valve built into them. Oftentimes, aftermarket companies don't know this either or just don't care. But our team cares about proper function just as much as we care about the appearance of every product we design. For pressure relief, our caps incorporate the OEM internals, so you get all the functionality of the original caps, ensuring a safe and reliable system in place. These caps offer superior style and performance-grade components that guarantee a reliable fit every time. Durable billet aluminum construction provides long-lasting protection and dependability that will upgrade your engine bay for years to come. PLEASE NOTE: These do require assembly and swapping the pressure relief valves from your old caps to your new billet caps.

Mechanical water pumps circulate coolant between the engine block, cylinder head, and radiators. Over time, the seals and bearings can wear out, leading to leaks from the impeller shaft and around the pump face. Some BMW water pumps have even had imellers that come loose from the shaft, resulting in little or no coolant flow. Plastic coolant flanges attached to the housing can become brittle over time, cracking or breaking off completely, leading to coolant loss and overheating. Restore cooling functionality and performance with a brand new pump directly from BMW. This coolant pump assembly includes the pump, the coolant support housing, four of the plastic coolant flanges, and a new water pump pulley.

Situated on the engine's oil filter housing, this set of gaskets plays a crucial role in sealing the housing to the engine block. Over time, exposure to heat and oil can cause these rubber gaskets to become brittle, compromising their ability to seal the mating surfaces effectively.

Given that oil flows from the block to the filter housing, any leaks from these seals can lead to significant issues. Fortunately, BMW offers a comprehensive set of these gaskets, providing a solution to all oil leaks and restoring your vehicle to optimal performance.

How can you identify if your oil cooler gaskets are leaking?

Oil drips beneath the car when it's parked. Visible oil accumulation on the intake/heat exchanger side of the engine block. Frequent low oil level warnings during driving.

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

Over time, rubber hoses and plastic coolant flanges can become brittle due to numerous heat cycles. This often leads to cracks and coolant leaks on the left side of the engine. Additionally, the two o-rings that seal this hose to the water pump flange and the thermostat module housing can flatten, leading to leaks when reinstalled. When servicing your cooling system, it is advised to replace this hose to prevent leaks and potential overheating. This is especially helpful due to its cramped location, requiring the intake manifold to be removed for replacement.

Carbon fiber is a staple in the performance world and has been incorporated into motorsports since the early 80s. Over time companies have taken it upon themselves to create new carbon products to add to your car that may have not been originally available. Autotecknic is no different. If you're looking for a carbon addition that has been made to the highest standards with premium materials, then Autotecknic's line of carbon additions is your one-stop shop. Made from dry carbon this shroud is durable and can stand strong in any driving environment. Dry carbon is the highest-quality version of carbon fiber products that are produced. Dry carbon fiber's name comes from its manufacturing process. Dry carbon fiber is formed by using a "pre-preg" or impregnated piece of carbon materials. This piece of carbon is first placed into a mold and then into a sealed vacuum (autoclave) to properly cure. This method creates the least amount of waste and forms a lighter version of carbon than the "wet" method. The autoclave vacuuming process of making dry carbon means fewer pinholes and virtually no air pockets in the carbon. Some customers have even reported better gas mileage and power gains.

Positioned directly in the charge pipe's path, the stock B58TU upper cylinder head cooling hose, primarily made of plastic, is prone to damage. A dislodged charge pipe can easily take out this cooling hose, leading to severe engine damage through rapid coolant loss and overheating.

To address this vulnerability, VTT has engineered a robust solution. By replacing the OEM rubber hose with a durable 7-ply silicone variant, they offer superior resilience and longevity. Furthermore, they've upgraded the factory plastic flanges to 6061-T6 billet aluminum with black anodizing, enhancing corrosion resistance.

This upgraded hose is the ultimate solution, providing protection against dislodged charge pipes and the heat generated from spirited driving or track use.

Key Features:

Direct factory replacement for easy installation 6061-T6 billet aluminum with black anodizing for improved corrosion resistance Durable 7-ply silicone available in three colors Upgrade your BMW B58TU engine with this enhanced cooling hose from Vargas Turbo Technologies for superior performance and reliability.

Engine oil coolers are critical for keeping oil temperatures in check, preventing premature breakdown and maintaining proper lubrication. When oil gets too hot, it loses viscosity and can't effectively protect vital engine components like bearings—which can lead to serious, even catastrophic, failures. If your oil cooler is damaged or has failed, replacing it is essential to protect your engine and keep everything running smoothly.

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.
