Find Parts That Fit Your Vehicle

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.

Plastic thermostat housing cracked on your M50?

Here are your choices: you can wait for the plastic factory thermostat housing cover to break and cause major overheating. (Even with a new stock cover, it won’t take long.) Or you can install a thoughtfully engineered all-aluminum thermostat housing cover from Active Autowerke and never experience this type of failure again. Currently there is no factory upgraded part to this problem. This is an aluminum extruded part that has all of the openings machine properly to fit like factory; from the mounting bolt holes, the seating of the thermostat to the sealing opening for the ORANGE gasket. Forged to exact factory tolerances, everything fits and this unit is a true easy bolt-on – especially suited for racing or load conditions like heavy traffic, where engine temp can rise rapidly. The housing is guaranteed never to break from overheating or over-tightening, and its CNC machined surface ensures a precise seat.

Unit comes complete with a new ORANGE sealing gasket; a new thermostat is recommended but not included.
For hotter climates, a 71 degree thermostat is recommended over the 82 degree unit.

Anything and everything BMW is the mantra at Active Autowerke. Since 1981 they have been serving the BMW community with custom turbocharger kits to a myriad of other innovative and inspiring performance parts.

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.

When you push your powerplant, thermodynamics push right back. The toll of high performance is higher heat load – and many stock components begin to complain. But Active Autowerke has you covered - this upgraded fan clutch increases viscous coupling of cooling fan blade speed to water pump speed, yielding increased airflow through the radiator for more efficient cooling. A simple, yet wonderful, thing.

This product fits the following BMWs:

Heat is the enemy of power, and the last thing you want is hot coolant heating your charge air even further right before it enters the charge cooler, but this is what BMW has done on the S58. This is done for emissions and quick warm-up purposes. However, If you are looking to make power on the S58, and are upgrading your charge cooler, or adding PI. While you are there, it takes 30 seconds to remove the coolant lines from the TB connections and replace them with our billet coolant delete kit. This completely removes the coolant from the Throttle body and provides a bypass for the coolant. Simply remove the two lines going to the throttle body, and run our hose in their place. You leave the coolant fittings on the TB open and avoid any unwanted heat being introduced into your charge tract. In our opinion a must for full effort builds. We take the work out of it for you. Kit included: One Plug and Play TB Coolant Delete Hose Kit Features: Billet 6061 Anodized coolant fittings for long leak-free life Reinforced 7-ply silicone hose for strength and longevity Vibration-resistant crimp clamps 100% plug and play, NO cutting or removing factory clamps or hoses.

Behr Replacement Radiator - More than likely, you are going to replace the radiator in your vehicle at least once. The joints where the cores meet the end tanks tend to get weak and are the first place to spring a leak. Impacts to the fins themselves can cause holes to form. Corrosion and clogging from the inside can make cooling less than effective and compromise coolant flow.

BMW's S55 motor is a modern marvel but one weak point, which Active identified is the entire cooling system for the intake which comprises the charge pipe, the aftercooler and the heat exchanger (or radiator). Finally there is a S55 aftercooler kit upgrade that is good enough to carry the Active Autowerke brand. Years of success in developing cars for motorsport has allowed Active to leverage its expertise to the top-mount charge air cooler on the F80 M3, F82 M4 and F87 M2 Competition. This aftercooler was made for the S55 and crafted using only high-grade aluminum to outperform the factory aftercooler in all situations from everyday driving to the toughest racing. The factory cooler was built to support a specific power target and environment. Many of you have increased the performance of the S55 which quickly overwhelms the stock cooler leading to heat soak and higher intake air temperatures which triggers the ECU to downgrade the performance until cooler air returns. Active's focus was not on a mass-market aesthetic add-on but a properly engineered improvement over the existing hardware. Active uses a tube-and-fin core designed specifically for the S55 and included turbulators to maximize the cooling efficiency in as small a package as possible. The end tanks are billet machined aluminum, not cast, folded, or bonded and ensure even distribution of the water throughout the internal aftercooler cores. High precision fittings, CNC machining, and TIG welding throughout ensures the highest quality construction to prevent pressure loss, and the lowest weight, in a bolt-on replacement. But Active also didn’t leave the aesthetics by the wayside as we dip the visible top of the aftercooler in a carbon fiber coating giving your installed cooling system a decidedly top market look to match the improved cooling performance. The Active silicone charge pipes for the F80 M3, F82/F83 M4 and the F87 M2 Competition improve the flow over the stock, compressed plastic pipes. The Active Silicone Charge Pipes allow you to maximize power on your F8X by securing all the boost that your S55 is making. These pipes replace the hot-side pipes leaving the turbos and into the top-mount aftercooler. The stock S55 charge pipes are notorious for developing hairline fractures at their plastic seams. These fractures or cracks are unnoticeable to the naked eye, but under boost pressure they open up leaking the desired charged air into the engine bay, and consequently can rob your S55 of it's full power potential. In addition, these leaks can trigger your S55's turbochargers to work harder to hit and maintain target boost pressure, potentially wearing them out sooner. Active uses silicone in this area because it will not contribute to heat soak and it's easier to mold for the correct clearances. Active uses a 5-layer silicone hose with all needed adapters and stainless hose clamps included. It fits perfectly with our CNC’d top-mount cooler.

Have you ever noticed how crisp and responsive your MINI was after that initial warm-up period, and wanted to keep that feeling for the rest of the day? This 180° F Thermostat is the solution. Not only does the engine maintain its fresh-start power, but also the under-hood temperatures are greatly diminished (see comparison table below). Now when your car sits after a hard run it won't cook and dry out everything under the hood as bad as it did in the stock configuration. This is great for the MINI owner that lives in a hot climate, or those that push their cars hard at the track or local twisty road.

Please Note: This thermostat does not include a replacement gasket. Reuse the gasket from the OEM thermostat.

Cold Weather Alert: If you encounter weather below 50º F or 10º C, please be aware that the ECU could throw a “check engine” light. This is no cause for alarm as the sensors are registering an anomaly and the thermostat is not harming the engine. The “check engine” light can be reset with a diagnostic tool or left as is. Please call if you have questions.
