BMW Cooling System Parts & Accessories for BMW Z3 (1996-2002)

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.

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.

The E36 Euro Spec Oil Cooler is exactly what it sounds like. E36 M3’s in Europe came equipped with an oil cooler that mounted under the radiator and was a popular upgrade for E36 owners in the US. Unfortunately, BMW discontinued the oil cooler and they have become harder and harder to find. BimmerWorld reached out to CSF to design a replacement unit that would fit exactly like the factory unit but perform even better. The original oil cooler used Tube and Fin construction. While this is acceptable for cooling performance, it is not a very robust design. CSF chose to go with a Bar and Plate construction to improve durability. While there is plenty of ground clearance, the cooler is low enough to see some potential abuse on the track. CSF wanted to offer that extra durability of a Bar and Plate cooler for track enthusiasts and those running their car on the lower side. The CSF Oil Cooler was designed to be a 1 to 1 replacement for the OEM unit in terms of fitment. This means it uses the same OE mounting points, hardware, and lines. For a Euro E36 M3 or US Z3M, the oil cooler will be a drop-in fit installation. E36 models that were not equipped with the oil cooler from the factory will need the BimmerWorld Euro Oil Cooler Bracket Kit which can attach to an OEM spec Radiator or the CSF #3054.

This fan is driven by the belt, engaged by the fan clutch.

This radiator expansion tank is used on E53 X5 4.4i and 4.6is with M62 engine, and Z3 2.3 2.5i 2.8 3.0i from 1999-2002. It is a common failure item as the plastic weakens over time and stress cracks will lead to coolant leaks. 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 less than six 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. This is the OEM Behr part - not an aftermarket. We have found that the aftermarket coolant reservoirs fail easier than the OEM Behr part. Hailing from Stuttgart, Mahle-Behr specializes in automotive cooling systems. From air conditioning to engine cooling M-B has you covered with OE-quality replacement parts.

The early M50/M52 engines had a serious weak point: the water pump. BMW originally used a plastic impeller in the water pump. This would degrade over time and eventually break apart. Your car overheats immediately. This water pump is the latest updated part with a composite impeller. The composite is stronger and lighter than the less-expensive metal impeller version. And it does not suffer from the problems of the early plastic design.

When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.

This waterpump fits the following BMWs:
1992-1999 E36 3 series - 323is, 323ic, 325i, 325is, 325ic, 328i, 328ic, M3 3.0 (S50/US), M3 3.2 (S52)

The thermostat on your vehicle controls the flow of coolant based on temperature. When you just start your engine, the thermostat remains closed to accelerate the warm up process. After a few minutes, it opens up to allow the warm fluid to flow. If your vehicle is overheating but not blowing warm air from the heater, the problem is more than likely your thermostat. If the thermostat gets stuck closed, it allows no fluid to flow and ends up overheating the coolant already in the engine. If your vehicle is not getting up to temperature when driving, the thermostat is more than likely stuck open. Your engine does not get up to the proper operating temperature where it runs the most efficiently. To fix this problem and get your vehicle's heat restored, replace your thermostat.
