BMW Cooling System Parts & Accessories for BMW E36 (1992-1998) M3

BMW vehicles are known for their robust performance, but the water pump is a notorious weak spot, often needing replacement every 60,000 miles.

During this service, it's wise to also swap out the thermostat to maintain the efficiency of your vehicle's cooling system. Turner Motorsport simplifies this process with our expertly curated Water Pump & Thermostat Replacement Kit.

This premium kit centers around the renowned EMP Stewart high-performance water pump--a favorite among BMW enthusiasts for its exceptional design. Featuring a stainless steel impeller, this pump enhances coolant flow by 20%. Complementing this is a low-temperature 68°C (154.4°F) Mishimoto thermostat, an upgraded aluminum thermostat housing, and Redline Water Wetter coolant additive. Together, these components make for the ultimate cooling system upgrade for your E36, E39, or Z3!

Replace the flimsy plastic bleeder screw used in the coolant expansion tank or in one of the cooling system hoses with this high quality, durable, aluminum bleeder screw. The stock plastic screw can deform over time due to heat or even regular use. We have even seen the head of the screw snap off, leaving the threaded body stuck in the expansion tank. This aluminum screw will help to prevent sudden failure of the bleeder screw, which can result in immediate overheating of the car.

The thermostat regulates the temperature of your coolant. At a predetermined temperature the thermostat will open to let coolant flow to the radiator and be cooled by airflow or the fan. Over time the thermostat will become stuck open or closed, leading to a variety of issues. A closed thermostat will never allow the coolant to reach the radiator and be cooled. Hot coolant will continue to circulate through the engine and absorb even more heat until boiling and the system overheats. An open thermostat is not as bad but is still not ideal - the coolant is always cool, with the temp needle always reading in the cool range. This tells the ECU to richen the fuel mixture to bring the car up to normal operating temp. So your fuel mileage decreases and the car runs rich.  

Replacing the thermostat is an easy but messy job. This thermostat includes the main o-ring (but a housing gasket may be required). Consider replacing the housing and any associated temp sensors while you're in there. The cooling system will need to be bled after.  

Most of the engines from the mid-1980s through the 1990s use the same thermostat design and they are interchangeable among the different temperatures. This is the 68*C thermostat, at the bottom of the temperature range. It should only be used in racing situations such as when deleting the engine fan. However, keep in mind that BMW spent a lot of time engineering the cooling system to work in all kinds of conditions and changing thermostat temperature is not recommended to fix any failures in the cooling system.  

Mishimoto makes coolant tanks, radiators and much more for your Mini/BMW. Established in 2003 their commitment to absolute quality in the aftermarket world is evident through the quality and performance enhancing products they offer.

Ensure a tight and leak-free seal in your BMW's cooling, vacuum, or intake systems by installing a new adjustable hose clamp. Over time, clamps can deform or lose their tightness due to aging or frequent removal, potentially causing leaks in your coolant or vacuum hoses. Avoid the risk of leaks by replacing old clamps with new hardware, offering peace of mind against coolant and vacuum system issues.

Key benefits of the adjustable hose clamp include:

• Maintaining a secure and leak-free seal in your BMW's systems.
• Preventing coolant or vacuum leaks that can affect performance.
• Adjustable size from 70mm to 78mm for versatile applications.

Upgrade your hose clamps to ensure optimal performance and reliability in your BMW's systems.
