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.

Our Turner Motorsport's full aluminum expansion tank was designed and engineered in house to help with the weak point in your E36 cooling system. The coolant expansion tank goes through heat cycles over and over again from regular driving, it is important that your expansion tank is doing its job to retain coolant to keep your engine operating temperatures down and keep your engine bay clean. Not only is this a major upgrade but also a great maintenance item to replace. Our expansion tank was designed to fit the OEM hoses for an easy install and comes with all the upgraded items you will need for a clean install,

If your E36 needs a new expansion tank, make sure this is the last expansion tank you ever need to buy. Our coolant expansion tank has a full aluminum construction and wrinkle black powder coat for durability. Expansion tank kit comes with all the accessories you need to replace your expansion tank once, and never have to worry about it again.

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

This high quality BEHR brand expansion tank is used on M50, M52, S50 and S52 engines, and is a common failure item on all E36 3 series with 6 cylinder engines (325/328/323 and M3) 1992-1999, Z3 with 2.8 liter, MZ3 Roadster/Coupe (S52), and E39 528i from 1997-1998. BEHR was the original equipment supplier to BMW, so you know the BEHR made expansion tank will be the highest quality available. Be leary of competitors selling this part for less -- is it a BEHR? Probably not. We only carry the BEHR brand expansion tank as it is the only one we use in our own BMWs.

If you are overhauling your coolant system, now is the time to consider preventative replacing this expansion tank. These are known to go bad, causing a leak which can leave you stranded. 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.

Need a new coolant level sensor too? If your coolant level sender is bad, your on board computer will constantly display a "low coolant" message (unless your coolant is actually low...). If you're replacing your expansion tank, now is a great time to replace this failure prone sensor. If you want a new coolant level sensor, simply choose from the option below. Because there are different sensors for different year/model BMWs, please be as specific as possible when you give us your car info during checkout (model, year, production date). Thanks!


This item fits the following BMWs:
1992-1998 E36 BMW 323ic 325i 325is 325ic 328i 328is 328ic M3

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.

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 electric fan for the E36 takes the place of the stock engine-mounted fan and offers several advantages - more horsepower by removing parasitic drag customizable temp control (with optional fan controller) frame included for a direct fit more reliable than a stock-style fan clutch The stock engine fan is mounted on the water pump shaft and spins with the engine. Torque from the engine is used to spin the fan, which could otherwise be used to power the car. It's not a lot of lost power and torque - Mishimoto measured a max gain of 6whp - but sometimes every little bit helps. And the other advantages of an electric fan make it a smart move. The Mishimoto electric fan uses a 16" slim profile electric fan that flows at 1,850 cubic feet per minute (CFM). The shroud and frame are black powedercoated steel and mounts to existing points on the radiator for a seemless install. Mishimoto has confirmed fitment with stock radiators as well as their own Performance and X-Line aluminum radiators. Hardware and instructions are included. An electric fan must be powered by a 12v source. A fan controller kit is optional and is activated by coolant temp. This is the preferred setup method but other types of controls may also be used. There are two styles of Mishimoto fan controllers - a sensor located in a 1/8" NPT plug or as a 6" probe inserted between the fins on the radiator. For BMW applications, the NPT plug is usually the best and Mishimoto has this port built into their radiator designs (most other aluminum radiators do as well). For the E36, Mishimoto has an optional dedicated wiring harness with a controller that takes power from the factory fuse panel.

This is a genuine BMW Motorsport part, designed specifically for BMW racing applications. We use this exact thermostat setup in our Championship-winning E46 330i race car. It is designed to be used on all M54 and M52TU double-VAN0S engines, as used in the 1999-2000 E46 323/328 and 2001-2005 E46 325/330. This 60 degree C (140 defrees F) thermostat comes complete with plastic thermostat housing. It does not use the plug and wiring for the stock DME so this should only be used with an aftermarket engine management system (Motec, Bosch, etc).

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.
