BMW Cooling System Parts & Accessories for BMW E30 M3 S14 2.3L

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.

    This is the stock replacement water pump for the E30 M3. This is the Genuine BMW pump and includes a new OE BMW gasket. It's always a good idea to have one as a spare. Even if it sits on your shelf for awhile it's going to be used at some point (and prices for Genuine E30 M3 parts aren't getting any lower). Aftermarket pumps have been in short supply and the quality hasn't been as good as the Original BMW pump so we have decided to stop offering aftermarket brands like Laso or Saleri. This is the Genuine BMW part, straight from BMW.

    This cooling package for the E30 M3 consists of all of the major components on the S14's cooling system. There are no major weak points to the E30's cooling system, unless you count skipped maintenance. The entire system is serviceable in individual components so you don't need to buy a complete package of parts. Many of the indivdual parts are on our site but we have setup this package to cover all or most of what you would need to perform a major overhaul. This overhaul package consists of an Genuine BMW radiator and then you build the package from there. Add hoses, sensors, water pumps, thermostats, gaskets, hose clamps, and more. We also sell the Original BMW antifreeze to finish off the job.

    Any problems with the cooling system are likely electrical. Sensors become corroded and fail over time which will send the incorrect signal to the corresponding unit, including the engine computer. Diagnosis of electrical type problems is easy and repair with the OEM Bosch or OE BMW sensors is not too expensive for a car like this. Electrical connections, particularly solder joints, can also become brittle and fail. These are not helped by the intense vibrations of the S14.

    Top Turner Tip for a healthy S14!
    E30 M3s always seem to have cooling problems at the most inconvenient time. If the temp gauge starts rising in the summer months first check and make sure your auxiliary cooling fan is working if it's not it's most likely the switch or the wiring going to the switch. Also remember that the E30 instrument conductor plate can make the gauge read whacky try tapping the gauge if it seems like it's acting up. When it's time to do a water pump (which weeps through a hole on the bottom before it goes completely) take a good look at the radiator too its not expensive and you have to remove it to install the pump anyway.

    Use the options below to build your package.

    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.

    Give your vehicle a cooler, more efficient running engine by installing a performance Mishimoto aluminum radiator. These radiators are a direct replacement to the factory unit making it an effortless install and provides up to a 30% more cooling capacity. Made from aircraft quality aluminum, these radiators have a dual row core and polished end tanks. So what are the advantages of an aluminum radiator? Well, first is the lightweight aspect of the radiator. You can run a larger radiator at the same weight as a stock unit. Also, in case of leaks years down the road, an aluminum radiator can be welded and repaired, saving costly replacement in the future. It is also much more durable, channeling heat better and resisting cracking and breaking, even at high temperatures. WARNING! Prop 65 may apply to this product.

    Red Line SuperCool Concentrate fortified with WaterWetter is a concentrated antifreeze/coolant designed to maximize the performance of your cooling system with superior protection against cavitation corrosion/erosion. Using SuperCool Concentrate diluted with distilled water protects the entire cooling system keeping new components like new for 5 years/150,000 miles and prevents further damage to older components. Red Line’s proprietary coolant additive formula enhances the fluid’s ability to transfer heat, reducing operating temperatures by up to 20*F and prolonging the life of the entire cooling system. Red Line's SuperCool is an OAT coolant that is a Nitrate and Silicate Free product with its own proprietary corrosion technology to offer superior protection for aluminum engines found in all European vehicles, performance vehicles, as well as other applications. SuperCool will not void the factory warranty either. It can be used to top off the existing coolant of any BMW and will not cause any ill-effects on the cooling system because it is silicate and nitrate free. It is still better to flush it out and switch completely to SuperCool to get all the full benefits of the product in performance and protection.
