BMW Cooling System Parts & Accessories for BMW 1 Series

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.

Engine running a little hot or is the temp gauge not telling you anything? The thermostat might be the likely problem. Many cooling issues start with the thermostat. This is electronically controlled by the engine computer based on the cooling demands from the engine. And cooling components are working harder than ever. Engine performance is also dependent on temperature - as temperatures rise and pass a certain threshold the engine computer will begin reducing power. Stay on top of your cooling maintenance by replacing critical components preventatively. This replacement thermostat fits many of the N51 N52 N53 N54 6 cylinder engines and is an OEM Behr part. 

The thermostat is located along with the water pump on the side of the engine. To gain access for removal you may need to remove the water pump as well. If the water pump is removed you MUST replace its mounting bolts. You can add them from the options below. We also have a bundled package that includes the water pump, mounting screws, connecting hose, and clamps if you want to replace everything together (recommended). 

This thermostat fits the following BMWs:

N54 and N55 engines are prone to water pump failure - replace every 60,000 miles. If your water pump is starting to fail, you may notice coolant leaks, or even hear a whining noise coming from under the hood. If you think your water pump is starting to fail, replace it as soon as you can. The main downside to an electric water pump is you may also notice nothing - nothing but overheating! Keep your eyes peeled for warning signs it may be time to replace your water pump.

Replace your fragile OEM plastic coolant bleeder screw, which is prone to cracking and failure, with a premium titanium upgrade built for strength and style under the hood. Factory plastic components weaken over time due to constant heat cycles, leading to brittleness and potential failure. Our titanium replacement delivers superior durability, being twice as strong as aluminum yet 45% lighter than steel, ensuring unmatched resilience and long-term reliability for your coolant system. More than an upgrade, it’s a must-have for engine longevity. CNC-machined from solid titanium, each screw features a laser-etched Burger Motorsports logo and is hand-burned to create unique color patterns—no two are alike. A heavy-duty replacement O-ring is included for a perfect fit.

If your vehicle is experiencing cooling issues, chances are the thermostat is the cause. Common symptoms include a prolonged warm-up at highway speeds from the thermostat being stuck open, or consistent overheating issues from the thermostat being stuck in the closed position. Either condition can result in poor performance and potential damage to vital components in your vehicle.

This is the radiator drain plug (petcock valve) for manual transmission E82 and E9X models. The plug actually has two drains built in - the traditional blue petcock valve which is part of the black hex plug. If you drain the coolant from your radiator through this plug you could be in for a nasty surprise. The black hex plug has tabs that lock it into position in the factory BMW radiator. Once it's installed the tabs lock in place. But if you remove the black hex the tabs snap off and the plug will no longer seal correctly! Do not drain your coolant without having one of these on hand as a spare! It's cheap insurance on a definite leak later on.

When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.

Fits auto transmission only.

Note: the Behr OEM radiator that we sell does not use this same drain plug. It has it's own drain plug that does not use the tabs. You won't need the factory BMW drain plug ever again.

The perfect upgrade for your connection between your thermostat and cylinder head. Designed using durable silicone and billet aluminum to greatly outlast the OE rubber and plastic combination. Some of the weakest points of the cooling systems in BMW's can come down to the OE plastic fittings breaking down from the constant changes in temperature, softening these plastic components. When this happens, even simply moving the hose slightly could cause the fitting to crack, causing the coolant to leak all over. The ECS design silicone hose with billet aluminum adapter retains OE fitment with superior strength to not only handle the performance, but also stand up to the wear and tear of a daily driver. Features: Manufactured from billet 6061-T6 and type III anodized for exceptional durability and corrosion resistance. Much stronger part than OEM plastic Will not become brittle and fatigue over time due to thermal cycling. This will prevent the part from breaking during removal and re-installation. Constructed of 4-Ply reinforced silicone for improved durability over the failure-prone OE rubber hose. Flourosilicone lined internal layer for exceptional chemical resistance. Silicone offers reduced thermal conductivity as well as improved resistance to ozone and UV degradation for improved performance and durability. Follows OEM form for perfect fitment. Utilizes OEM O-ring 11537545278 to ensure a proper seal. Replaces Genuine BMW Part Number: 11537545890
