BMW Cooling System Parts & Accessories

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.

BMWs are well-known for their problematic cooling systems, which are often the cause of irreversible engine damage and a hefty repair bill. The coolant expansion tank—a crucial component responsible for holding hot engine coolant under high pressure—is a common cause of cooling system issues. Unfortunately, BMW chose to manufacture the factory F8X expansion tank out of plastic. After years of exposure to high coolant temperatures, ambient engine bay heat, and chemical-rich antifreeze, the plastic degrades, eventually weakening enough to fail catastrophically. With this issue in mind, our team of BMW enthusiasts engineered the ultimate cooling system upgrade for F80 M3, F82/F83 M4, and F87 M2 Competition owners: a robust intercooler expansion tank that is built to last! Constructed from durable 5052 TIG-welded aluminum, this tank withstands high temperatures and pressures without deteriorating over time. Unlike the OEM molded plastic tank, this alternative is not prone to cracking, leaking, or weakening. With the Turner Motorsport Aluminum Intercooler Expansion Tank Kit, you'll never experience expansion tank failure again! Ideal for track-driven cars, this upgrade prevents catastrophic failures that cause charge-air temp spikes and limp mode due to coolant loss in a system with no level sensor. Unlike other aftermarket coolant reservoirs, this tank retains the factory coolant capacity and features a laser-cut Turner logo plate at the top of the tank to provide an exact level for filling. To guarantee exact fitment, the upgraded tank was designed using advanced 3D CAD modeling. All bungs, nipples, and fittings are precision-machined to ensure a secure seal with factory hose ends. Designed for both high-performance builds and daily drivers, the tank features a premium wrinkle black powder coat for a sleek "OEM+" look. This durable finish goes beyond style—it prevents corrosion for long-lasting reliability. Avoid the risks of the factory expansion tank—upgrade your S55-equipped BMW today and drive with confidence!

Upgrade your cooling system setup with our Heavy Duty Radiator Mounting Brackets, engineered to deliver maximum structural support and a refined engine-bay aesthetic. After decades of heat cycles and hard driving, your E30's factory plastic mounts inevitably become brittle, faded, and prone to cracking, risking damage to your radiator. Our radiator mount upgrade completely replaces those tired OEM units with a high-strength alternative built to handle the rigors of spirited driving, track days, and engine swaps. Whether you are performing a full cooling system refresh or executing an M5X swap that utilizes an E36-style radiator, these brackets provide the ideal balance of precision fitment and rugged dependability.

Crafted with a premium brushed stainless steel finish, this kit does more than secure your radiator; it radically improves the visual appeal under the hood by swapping out cheap, weathered plastic for durable steel hardware. Designed as a true direct bolt-on solution, the brackets align seamlessly with factory mounting locations, eliminating the need for frustrating custom fabrication, cutting, or drilling. They clamp down firmly to eliminate unwanted radiator movement, ensuring your cooling stack remains locked in place under heavy vibration.
