This is a compete cooling system overhaul kit, which includes all of the common Z3 cooling system failure parts bundled into a complete package.

The Z3 cooling system's primary cooling components are prone to failure within 100k miles (or less in certain cases). A failure in the cooling system can lead to overheating and catastrophic engine failure. Don't gamble your engine! By replacing these core items preventatively, such as the radiator & waterpump, you are defusing what could be a ticking cooling system time bomb. And if you've had a failure of one of these parts, now is the time to refresh your cooling system. Our kit includes one radiator, OE BMW water pump (with composite impeller and O-ring), OEM thermostat and housing (complete with sensor and gasket), radiator cap, expansion tank, and new hoses (as pictured).

Optional items (which can be added below):
- Upgrade the waterpump to a Stewart/EMP High Performance pump
- Original BMW antifreeze
- Aluminum water pump pulley (stock plastic ones are known to crack)
- Cooling fan clutch

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!

Just like the rest of your vehicle's major systems, the cooling system must also be addressed periodically to ensure proper cooling and component reliability. Plastic and rubber components become brittle and prone to splitting or cracking after long periods of heating and cooling cycles, especially in colder climates! The coolant itself can degrade or become contaminated, leading to potential corrosion or freezing issues. Finally, thermostats and sensors can fail completely, preventing proper cooling and/or coolant temperature readings to become inaccurate.

To make sure you are not left stranded on the side of the road with an overheated engine, we have put together this Basic Cooling System Service kit. This kit contains all of the most-likely-to-fail components, giving you peace of mind knowing your engine will continue to run cool for another 60,000+ miles.

See kit contents below for all included components.
