Find Parts That Fit Your Vehicle

Packaged by Turner BMW Cooling System Parts & Accessories

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.

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.

This is a compete cooling system overhaul kit, which includes all the common cooling system failure parts bundled into a complete package. This cooling system package is for the E53 with the M54 engine. 

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 thermostat housing, radiator, and 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 entire cooling system. Keep on top of the cooling needs of your engine for your own piece of mind. Potential buyers also see the upside of a properly maintained car with receipts. 

 

This kit fits the following BMWs:

2000 - 0/2002 - E53 3.0i with manual transmission

Looking to free up horsepower and upgrade your cooling? Then this Electric Fan Conversion kit is the perfect choice! The fan and clutch that connect to the water pump add additional rotating mass to the drive line. By removing them and converting your system to an electric fan, the engine has to do less work, giving you that extra little bit of power. In this kit we include a lower temperature thermostat, coolant additive, and low temperature fan switch that engages the electric fan at a lower temperature, keeping your engine cool and lowering the drag and unneeded weight from the front end of your BMW.

Included in this kit:

  • 80 degree Celsius thermostat
  • 1 liter of Genuine BMW coolant
  • Water Wetter coolant additive
  • Low-temperature coolant temperature sensor/switch
  • 16 inch Electric fan 
  • Electric fan mounting kit
  • Fan controller kit with probe sensor 
  • Fan delete nut

Fits the following BMWs:
1992-09/1995 E36 BMW 325i/is/ic 328i/is/ic M3

This Cooling Kit for the 1988-1992 E30 325i covers all of the major replacement parts for the original cooling system. We start with an OEM Behr radiator and then you choose the additional parts you need to replace next. Add hoses, sensors, water pumps, thermostats, gaskets, hose clamps, and more. We also sell the correct Original BMW antifreeze to finish off the job.

Of the systems in your E30, the cooling system is not where you want to let slide or skip maintenance. Almost nothing will ruin your day more than an overheating engine and it's usually at the absolute worse time. Maintaining the cooling system is easy and you can do most or all of the work yourself with ordinary tools. There's no reason not to address a leaky or out of date cooling system right away.

To save you time and money, we recommend replacing major components with related parts.
Radiator (manual: 17112241912; automatic: 17112241913)
Upper (#11531722218) and lower (#11531718980) hoses to thermostat.

This is a compete cooling system overhaul kit, which includes all the common cooling system failure parts bundled into a complete package. This cooling system package is for the 1999-2000 528i with the M52TU engine and the 2001-2003 525i and 530i with the M54 engine. This package applies to cars equipped with either the manual or automatic transmission.

Much of the later E39 cooling system is strong and reliable and doesn't suffer the same types of problems associated with earlier E39 and E36 systems. But there is still the potential for serious cooling system and engine-related failures. Several of the primary cooling components are prone to failure within 80k miles (or less in many 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 thermostat housing, radiator, and 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 entire cooling system. Our kit includes an OEM Behr radiator, an Original BMW water pump (with updated composite impeller), thermostat with housing, radiator cap, and new radiator hoses.

Optional items (which can be added below):
- Original BMW antifreeze
- Upgrade the water pump to a Stewart EMP High Performance pump
- Add a new coolant expansion tank (known for cracking)
- Add a new coolant level sensor (known for failing / throwing "check coolant" messages)
- Add a new coolant temp sensor (located in lower radiator hose and the seal ring may cause leaks if re-used)

This cooling system overhaul kit fits the following BMWs:

There are three versions of the water pump for the early 1997-1998 540i: OEM plastic impeller, updated metal impeller, and the more recently updated composite impeller. We recommend either the metal or composite impeller. These are what we use the most in our shop and what our technicians are comfortable with. On more recent models, BMW has used the composite impeller as original. There doesn't seem to be evidence of the plastic failing on this design (it did on the E36 3-series) but we feel most comfortable with the other options. Both the metal and composite manufacturers are OEM for BMW.

Top Turner Tip!
On the 1987 325i, pay particular attention to the alternator fan blades and the clearance to the lower radiator hose. As the engine shifts on worn motor mounts, and the alternator twists on worn bushings, the cooling blades can slice right through the hose. Replace the alternator bushings and use our motor mount reinforcements. Or convert the whole system to the 1988+ cooling system which moves the lower hose to the other side of the radiator.

To save you time and money, we recommend replacing major components with related parts.
