BMW Cooling System Parts & Accessories for BMW Z Series G29 (2019+)

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.

Engine oil coolers are critical for keeping oil temperatures in check, preventing premature breakdown and maintaining proper lubrication. When oil gets too hot, it loses viscosity and can't effectively protect vital engine components like bearings—which can lead to serious, even catastrophic, failures. If your oil cooler is damaged or has failed, replacing it is essential to protect your engine and keep everything running smoothly.

Dramatically increase the cooling performance of your Supra with Mishimoto's new Performance Aluminum Radiator. Key Features: All aluminum construction More durable and longer-lasting than plastic components 30% more capacity in the same space 180% Increase to external fin surface area Excellent fit and finish Unbeatable lifetime warranty and accident-forgiveness Mishimoto radiators address all of the defects and deficiencies of the stock Supra auxiliary radiators in a well-engineered and price-competitive direct replacement pair. Mishimoto's radiators feature an all-aluminum design that replaces the factory plastic and aluminum stock radiators. BMW style plastic end tanks are notorious for cracking and leaks, whereas the Mishimoto has aluminum end tanks that will never fail. Mishimoto also allows a 30% increase in coolant capacity into the radiator that fits in the original location with no modifications. More coolant volume means the fluid is not heat soaked for as long (less superheated fluid circulating through the engine). For a direct replacement performance radiator, the Mishimoto is hard to beat! Mishimoto was established in 2003 as a supplier of cooling components for drift and rally cars. Their radiators and intercoolers soon found a strong following in the hyper-competitive drift scene where high horsepower and prolonged high revs dictate the need for durable and robust cooling solutions. The catchy Mishimoto name is a combination of the name of the founder's family pet - Mishi - and "moto". All products are designed and tested in the USA using state-of-the-art CAD tools and prototyping and with the continuous evolution of product design. Mishimoto is so dedicated to quality that they offer a limited lifetime warranty and accident forgiveness. WARNING! Prop 65 may apply to this product.

Engine oil coolers help reduce the oil temperature, preventing the oil from breaking down prematurely and losing its lubricating properties. Engine oil coolers play a crucial role in regulating oil temperature, ensuring proper lubrication, and optimizing engine performance and longevity. Engine oil that is too hot drops in viscosity and does not provide adequate lubrication to sensitive engine components such as bearings, which can fail catastrophically if not properly lubricated. If your engine oil cooler has been damaged or has failed we recommend replacing it to ensure no damage occurs to your engine.

Modern BMW thermostats are electronically controlled, allowing the DME/ECU to directly regulate coolant flow throughout the engine and its components. This system enables the thermostat to operate based on a broader range of temperature inputs, such as coolant, cylinder head, engine block, and oil temperatures, for more refined control of engine warm-up and temperature across diverse conditions. Unlike traditional thermostats, which simply open or close to permit coolant flow, this system uses a rotary valve for more dynamic control. The rotary valve adjusts to various positions, allowing for partial or full coolant flow to designated passageways as needed. This precision control helps your BMW's engine reach optimal temperatures quickly and ensures efficient heat management under various driving conditions.
