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 2008-2010 E60 528i/528xi models with an automatic transmission (N52 engine).
Much of the later E60 cooling system is strong and reliable compared to the previous generation 5-series models. But there is still the potential for serious cooling system and engine-related failures. On the N52 engine the electric water pump is the weakest link. It will fail without much warning and shut down the engine. Preventative replacement is the best course of action and the water pump and thermostat should be done before they reach 60,000 miles. Several other cooling components are due for replacement by 100,000 miles to prevent other breakdowns. 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 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 base kit comes with the OEM Behr thermostat, Original BMW electric water pump with mounting screws, and the u-shaped hose between the pump and thermostat. From there you can add additional items to complete the overhaul - radiator, expansion tank, cap, and new radiator hoses..
E60 528i Automatic Radiator Options. There are two styles of radiators for the E60 6-cylinder and automatic transmission: original and updated. You can use either radiator as long as you have the correct corresponding parts to go with it. Both radiators are still available from BMW or the OE supplier Behr. If it were up to us we would prefer the updated style because it won't cause any confusion down the road and it reduces the number of potential leak points by eliminating an unnecessary fitting.

E60 528i Cooling Hoses. There are a lot of hoses on the N52 engine. Not all of them need to be replaced during an overhaul but it would be a good idea. The hoses themselves don't wear but the metal spring clips on the connector lose their tension over time and that can lead to a leak. It's worse when re-using a hose after it's already been disconnected. Since our package includes the thermostat, water pump, and radiator we offer all of the hoses related to those components. Use the diagram on the right to see where each is connected in the engine bay. Evaluate your current hoses and then decide which ones to replace. One note about the lower radiator hose: when ordering a new hose you must order a new temp sensor. Do not reuse the original temp sensor as it will leak on the new hose.

The cooling system is one of the major weak points on the N62 engine in the 550i/650i. The water pump itself won't last more than 100,000 miles in most cases and the engine itself is prone to coolant leaks from multiple locations. So a major 550i cooling system overhaul should be planned before the 100,000 mile mark. Aside from obvious leaks the 550i water pump will also squeal or screech indicating the bearings inside have worn. This package covers the water pump, thermostat, and radiator for the 2006-2010 E60 550i and E63 650i with a manual transmission.
The entire cooling system on the 550i is susceptible to leaks and poor performance. The condition of the rest of the cooling system should be considered along with the water pump and thermostat. Replacing the water pump will expose the front of the V8 engine where more problem areas may appear so plan accordingly. The biggest problem is the V8 valley pan gaskets and inner coolant tube seals. The tube carrying coolant through the valley is prone to leaking and replacement is a major job (see our valley pan pipe kit here). Additional items recommended to be replaced during the water pump job are: cooling hoses, expansion tank and cap, temp sensors, drive belts, and pulleys and tensioners.

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.
