This cooling overhaul will cover just about everything you could replace on the 325/330's cooling system. We start with the basic water pump and thermostat bundle. These are already vital to the health and durability of the N52 325/330. 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, cooling hoses, and the BMW antifreeze. This package fits 325/330 with N52 engine and 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 E90/E92 every 80-90,000 miles and to check for soft/pending codes at every 5,000 mile service .

Base Cooling Overhaul Package - Water Pump and Thermostat

(click to expand)

Includes:
+ Genuine BMW electric water pump, p/n 11517586925
+ mounting screws for water pump (set of 3), p/n 11510392553
+ OEM Behr thermostat, p/n 11537549476
+ Original BMW connecting hose from thermostat to water pump, p/n 11537521049
+ OEM-style hose clamps for hose (x 2)

The water pump on the N52 engine has more cooling responsibilities than ever before. 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.

Coolant Hoses

(click to expand)

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 325/330 water hoses during this job (see diagram):

17127531579, upper radiator hose (A)
17127531581, lower radiator hose (B)
11537552396, water pump to engine �
11537545890, thermostat to cylinder head (includes new o-ring) (D)
There are other hoses too but they are not often replaced during a radiator swap (radiator vent hose and heater core hose) and they don't see much wear. We offer these as well if you want a complete set (see Additional Items at the bottom of the page).

Expansion Tank Options

(click to expand)

The expansion tank on the 325/330 is not prone to failures (unlike previous 3-series cars) so a new one is not strictly required. There aren't many seams or stress points for it to crack and we haven't heard of too many issues. But we wanted to offer it as part of a complete overhaul in case you want to cover everything. Simiarly, the level sensor is not required unless you're getting erroneous 'low coolant' warnings from the dash/iDrive. We do strongly recommend replacing the cap because that is designed to be the weak point in the system. The cap is what regulates the pressure inside the system and it should be replaced every few years anyway.

Coolant Temp Sensors

(click to expand)

There are two coolant temp sensors on the E90 325/330 - in the lower radiator hose and in the cylinder head. Both feed coolant temps to the ECU to regulate the water pump and cooling fan. You should replace the one in the lower radiator hose because it's one of the main sources for coolant leaks, especially when the old sensor is re-used in a new hose. The sensor in the cylinder head is not as prone to leaks and it's easily accessible so you don't have to replace it right away. But we offer it with the package in case you want to have a complete cooling system overahul.
13621433077, coolant temp sensor (in lower radiator hose)
13621433076, coolant temp sensor (in cylinder head, next to oil filter housing)

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.

Because it is subjected to such drastic changes on a regular basis, it can often crack or break. You want to keep all the coolant in your vehicle in the cooling system. If your tank has experienced damage such as cracking, nipples breaking off, or mounting point damage, you will need to replace it.

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

(click to expand)

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 328 water hoses during this job (see diagram):

17127531579, upper radiator hose
17127564478, lower radiator hose
11537613176, water pump to engine
11537534880, gasket for #176 hose
11537545890, thermostat to cylinder head (includes new o-ring)
17117524710, radiator to auto trans cooler
There are other hoses too but they are not often replaced during a radiator swap (radiator vent hose and heater core hose) and they don't see much wear. We offer these as well if you want a complete set (see Additional Items at the bottom of the page).

Expansion Tank Options

(click to expand)

The expansion tank on the 328 is not prone to failures (unlike previous 3-series cars) so a new one is not strictly required. There aren't many seams or stress points for it to crack and we haven't heard of too many issues. But we wanted to offer it as part of a complete overhaul in case you want to cover everything. Simiarly, the level sensor is not required unless you're getting erroneous 'low coolant' warnings from the dash/iDrive. We do strongly recommend replacing the cap because that is designed to be the weak point in the system. The cap is what regulates the pressure inside the system and it should be replaced every few years anyway.

This cooling overhaul will cover just about everything you could replace on the 328 SULEV's cooling system. We start with the basic water pump and thermostat bundle. These are already vital to the health and durability of the N51 328i SULEV. 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, all of the 328 SULEV cooling hoses, and the BMW antifreeze. This package fits 128i/328i SULEV with N51 engine and automatic transmission. Some of the components are different for the automatic models because of the auto transmission oil cooler.

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 E90/E92 every 80-90,000 miles and to check for soft/pending codes at every 5,000 mile service .

Base Cooling Overhaul Package - Water Pump and Thermostat

Coolant Temp Sensors

(click to expand)

There are two coolant temp sensors on the 328 SULEV - in the lower radiator hose and in the cylinder head. Both feed coolant temps to the ECU to regulate the water pump and cooling fan. You should replace the one in the lower radiator hose because it's one of the main sources for coolant leaks, especially when the old sensor is re-used in a new hose. The sensor in the cylinder head is not as prone to leaks and it's easily accessible so you don't have to replace it right away. But we offer it with the package in case you want to have a complete cooling system overahul.

Engine running a little hot or is the temp gauge not telling you anything? The thermostat might be the likely problem. Many cooling issues start with the thermostat. This is electronically controlled by the engine computer based on the cooling demands from the engine. And cooling components are working harder than ever. Engine performance is also dependent on temperature - as temperatures rise and pass a certain threshold the engine computer will begin reducing power. Stay on top of your cooling maintenance by replacing critical components preventatively. This replacement thermostat fits many of the N51 N52 N53 N54 6 cylinder engines and is an OEM Behr part.

The thermostat is located along with the water pump on the side of the engine. To gain access for removal you may need to remove the water pump as well. If the water pump is removed you MUST replace its mounting bolts. You can add them from the options below. We also have a bundled package that includes the water pump, mounting screws, connecting hose, and clamps if you want to replace everything together (recommended).

Common symptoms include a prolonged warm-up at highway speeds from the thermostat being stuck open, or consistent overheating issues from the thermostat being stuck in the closed position. Either condition can result in poor performance and potential damage to vital components in your vehicle.

This is the radiator drain plug (petcock valve) for manual transmission E82 and E9X models. The plug actually has two drains built in - the traditional blue petcock valve which is part of the black hex plug. If you drain the coolant from your radiator through this plug you could be in for a nasty surprise. The black hex plug has tabs that lock it into position in the factory BMW radiator. Once it's installed the tabs lock in place. But if you remove the black hex the tabs snap off and the plug will no longer seal correctly! Do not drain your coolant without having one of these on hand as a spare! It's cheap insurance on a definite leak later on.

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.

Fits auto transmission only.

Note: the Behr OEM radiator that we sell does not use this same drain plug. It has it's own drain plug that does not use the tabs. You won't need the factory BMW drain plug ever again.
