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.

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. Replace your leaking unit with a factory replacement and get that jug of coolant out of your back seat.

This is the fan that turns on when the air conditioning is activated electronically. It’s not driven by the belt and it pushes air through the condenser. If it breaks, it might be an electrical issue that usually occurs in the motor within the fan, as it will fail to engage. There is also a chance that the blades might get damaged as well. No matter how your fan got damaged, be sure to replace it to keep air circulating evenly.

We have found that the expansion tanks should be replaced based on age as well as condition. Expansion tanks seem to have a lifespan of fewer than six to eight years before they show signs of fatigue and wear. Pre-emptively replacing the expansion tank as part of an overall maintenance plan can prevent you from getting stranded from a sudden failure later on.

The water pump in your vehicle keeps all that coolant flowing freely. If it begins to fail, overheating problems are inevitable. Don't take a chance on doing damage to engine internals by not replacing your water pump. This has been a common problem amongst most German vehicles. Water Pump failure can lead to your vehicle making an unnecessary trip to the repair shop. If your pump stops working, coolant temperatures rise rapidly and can overheat the engine, leading to head gasket or even piston ring failure. This is a great preventative maintenance item when doing any type of timing belt replacement. This is a common replacement around 60,000 miles.
