BMW Cooling System Parts & Accessories for BMW F82 M4 S55 3.0L

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.

When it comes to BMW's we all know the weak point is commonly in the cooling system, many models proving hard to bleed the air pockets out after the refresh. The coolant refill tool solves this problem, ensuring that you get an air pocket free fill. The entire task is as simple as draining the system like normal, reinstalling the drain plugs and hooking the tool up to your refill location. The reason this tool works so well is due to the venturi valve, it converts air pressure from the compressor to vacuum inside the cooling system, then with a twist of a valve sucks coolant right into the system using the vacuum pressure.

**** DOES NOT INCLUDE HARDWARE ****** The S55 engine is no stranger to oil cooling problems, that’s why we recommend installing the MSL Oil Thermostat. The standard oil thermostat will reach around 120 degrees Celsius with a normal driving style. The MSL Oil Thermostat will open at a lower temperature than the standard oil thermostat (at 85 degrees Celsius) and will keep the temperature stable between 95 and 105 degrees Celsius. Installing the MSL thermostat ensures a cooler oil temperature which will result in more stable performance, but above all this improves the reliability of the engine. It is recommended to install the thermostat, especially for cars that are tuned. The Thermostat is plug-and-play and made out of a solid block of high-grade aluminum at our own facility. It is equipped with a real thermostat, not an always open solution. The oil will still reach the operating temperature at the same time as a stock thermostat Features Include: 20°C/68F Lower Than Stock Rock Solid Housing - CNC machined housing. Real Thermostat - Equipped with a real thermostat, not an always open solution. For use in hot and cold climates Quick Installation - Takes only 30 minutes to install.

Like the other cooling systems on the F8X, the factory auxiliary radiators do a pretty good job in stock form. However, once you start adding a lot of power and pushing the car in aggressive driving conditions, the factory systems start to show its limitations. As more and more owners have pushed the limits of their S55, CSF saw the need and demand. The F8X platform is also almost a decade old with the newest examples being at least 5 years old. Over time the original coolers end up with damaged or clogged fins that greatly reduce their cooling capacity. CSF designed the coolers to be a true “Drop-in Fit” for easy installation. Each cooler mounts in the factory location and uses the OEM quick connections. The High-Performance Auxiliary Radiators work in conjunction with the rest of the cooling system to reduce temperatures. They not only help keep temperatures in optimal ranges, but prolong the heat soak threshold. There’s nothing worse than having your track session cut short because you need to do a cooldown lap. Each CSF F8X Auxiliary Radiator can fit the left or right side. The fitting and plugs are swappable and can be easily setup for either side. Compared to the OEM F8X coolers, the CSF units are a significant upgrade. CSF eliminated the OE plastic mounting pod by incorporating it into the modular design that fits both sides. This design improvement increases the size of both the core and tanks. The extra space taken from the mounting pod allowed for a ~7% increase in Core Size and an ~10% increase in Tank Volume. With a larger 2-row 42mm core, cooling efficiency and capacity are drastically increased. The high efficiency core using CSF’s Exclusive B-Tube Technology maximizes airflow and heat dissipation. 100% All-Aluminum construction ensures the best performance and durability. The mounting pins and brackets are much stronger and more durable than the OE plastic pod mounting system. In addition, the black finish provides extra protection and offers a stealthy look behind the grilles of your F8X. In addition, the CSF auxiliary radiators also feature integrated bolt on rock guards to keep the coolers safe. You’ve no doubt heard horror stories about OEM coolers getting punctured and spilling fluids all over the road or track. Now you can feel more confident that your cooling system is safer from road debris. CSF used a modular design so the auxiliary radiator can fit either side. There are several benefits to this type of design and offers several benefits. One of those benefits is for serious track applications. Having spare parts is always a great idea. Having one auxiliary radiator that fits both sides where you’d normally need one of each is a big cost and space saver. Getting an extra as backup is more cost/space efficient with the CSF units. Product Features: Sold Individually – all applications require 2 auxiliary radiators Multi-Fit – Fits Both Left & Right Side 2-Row 42mm High-Performance Core Featuring CSF’s B-Tube Technology Ultra Efficient 6.5mm Tall Fins with a Multi-Louvered Design for Maximum Surface Area Contact Tank Volume increased by 10% and Core Size Increased by 6.4% 100% All-Aluminum TIG-Welded Construction OEM Style “Quick Connect” Inlet/Outlet True “Drop-in Fit” Requires No Modifications to Install Includes Detachable Rock Guard Individually Leak and Pressure Tested High-Performance Upgrade Suitable for Professional Racing, Street Performance, or OEM Replacement Satin Black Finish for OEM+ Look 2-Year Limited Warranty Replaces BMW # 17112284603 or 17112284604 Applications: 2015-2018 BMW F80 M3 (incl.

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.
