This Cooling Kit for the 1987 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 There's no reason not to address a leaky or out of date cooling system right away.

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.
Radiator (manual: #17111468074; automatic: #17111468075)
Upper (#11531286914) and lower (#11531279895) hoses to thermostat.
Thermostat with o-ring and housing gasket (#11531713040).
Water pump (#11519071562)
Timing belt and tensioner (#09-9320-000).
Associated hoses with each of the above.
 - hose from water pump to thermostat (#11531287651)
 - hose from expansion tank to water pump (#11531289257)
 - hose from throttle body to thermostat (#13541705568)

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 cooling overhaul will cover just about everything you could replace on the 535's cooling system. We start with the basic water pump and thermostat bundle. These are already vital to the health and durability of the N54 engine. But to properly maintain these cars for the long term, the rest of the cooling system must be refreshed and preventatively replaced. Here you can add a radiator, expansion tank, 535 cooling hoses, and the BMW antifreeze. This package fits 535 with a manual transmission.

The sophisticated electronics of the ECU and water pump means catastrophic overheating should be a thing of the past. But the downside is that the electronics can shut down without any warning or symptoms. And troubleshooting is equally frustrating since the water pump electronics are not readable or serviceable. There are several clues to a faulty thermostat or water pump - the fan runs at full speed all the time (even immediately on a cold start), pending (soft) fault code for low coolant flow, or the water pump can be heard running constantly. But when the pump fails it's an immediate shut down of the engine which can be a major inconvenience and lead to additional repairs that might have been avoided with preventative maintance. We recommend a full cooling system overhaul on the E60 535 every 80-90,000 miles and to check for soft/pending codes at every 5,000 mile service .


Base Cooling Overhaul Package includes:
+ Genuine BMW electric water pump, p/n 11517588885 or 11517632426
+ mounting screws for water pump (set of 3), p/n 11517602123
+ OEM Behr thermostat, p/n 11537549476
+ Original BMW connecting hose from thermostat to water pump, p/n 11537545665
+ OEM-style hose clamps for hose (x 2)

The water pump on the N54 engine has more cooling responsibilities than ever before. Not only must it provide cooling for the engine, but it's also pumping fluid used to cool the turbocharger oil and transmission oil. The good news is that the pump only works when, and only as much, as it needs to. That means the system can actually stop the pump when it doesn't need to be running. The bad news is that it's now an electrical part, so a failure is usually immediate and with no warning. The preventative replacement is your only insurance from a very inconvenient and costly breakdown in the future. Plus you get the very latest BMW water pump design with any improvements they've made since your original pump was installed.

Cooling Hoses
With regular driving the hoses should last a very long time. Even the plastic connectors seem to be holding up well. But as a preventative measure new hoses are recommended. We have also seen issues with re-using hoses as the spring connectors get weak over time and may not have the strength to hold the hose in place. They seem to have a tough time holding tension especially when they have been removed and reinstalled. In the interests of a thorough overhaul we recommend replacing these 335 water hoses during this job (see diagram):
  • 17127560968, upper radiator/radiator vent hose
  • 17127565075, lower radiator hose
  • 17127560973, return hose

    BMW has been designing notoriously failure-prone cooling systems since the late 1980s. The coolant capacity in most BMW engines is not sufficient to accommodate any driving or overheating near red zone temperatures. After the gauge reaches this critical area, it is common for thousands of dollars in damage to occur. Stop the problems before they arise. If your vehicle has 80,000 miles or more, replace all of these components to ensure that your vehicle stays healthy. To keep everything in top order, continue to replace these components at 80,000 mile intervals. Water pump failure, cracked housings, and expansion tank leaks will not be a concern once all these problem parts are replaced.

    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 1997-1998 540i with the M62 4.4-liter engine (non-VAN0S). This package applies to cars equipped with either the manual or automatic transmission (select the appropriate parts in the menu below).

    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.

    Basic Kit Contents:
    1711702969, radiator (OEM Behr)
    11510393340, water pump (OEM)
    13621703993, coolant temp sensor (located in the water pump housing)
    11531437526, thermostat with housing and sensor (OEM Behr/Hella)
    11531745595, upper radiator hose (OEM)
    11531741409, lower radiator hose (OEM)
    11531741404, expansion tank hose (OEM)
    17111741167, expansion tank (OEM Behr)
    17111742231, expansion tank cap (OEM Behr)

    Cooling Kit Options:
    540 Water Pump Options
    (click to expand)
    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.

    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:
    1999-2003 E39 BMW 525i 528i 530i
