BMW Cooling System Parts & Accessories for BMW 5 Series E34 (1987-1995)

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.

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)

This radiator is made by Nissens, an original equipment supplier to BMW. The cooling system is a weak point on most BMWs, causing many BMWs to develop issues in as few as 50,000 miles. Overheating your engine can and usually will result in large repair bills and sometimes a warps the cylinder head(s), requiring intensive repair or full replacement. Prevent potential failure by replacing your radiator early, keeping your BMW happy and cool. This is the brand we use exclusively on our own BMWs, and think you should as well! As a leading source of high-performance BMW parts and accessories since 1993, we at Turner Motorsport are honored to be the go-to supplier for tens of thousands of enthusiasts the world over.
