BMW Cooling System Parts & Accessories for BMW G82 M4 S58 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.

Auxillary water pumps are electric water pumps that pump coolant to critical components of your BMW. A failing pump can cause excessive noise and intermittent cooling issues, leading to potential damage if not replaced quickly enough. If the electric motor dies completely, chances are any parts downstream from the pump will overheat and fail, leading to costly repairs and replacements.

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. Fully reversible
