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).  

For the following BMW engines:
N54 N52

Eventually, you are going to replace the radiator in your vehicle. The joints where the cores meet the end tanks tend to get weak, crack or split and cause a leak. Impacts to the fins can cause cracks and punctures. Corrosion and clogging from the inside can make cooling less than effective and compromise coolant flow. Replacing your leaking unit with a genuine BMW OEM replacement restores flow and prevents overheating.

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 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 325/330i. 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 325/330 cooling hoses, and the BMW antifreeze. This package fits 325i/330i/xi with N52 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
(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.
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 325/330 water hoses during this job (see diagram):
  • 17127531579, upper radiator hose
  • 17127531581, 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 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.

13621433076, coolant temp sensor (in cylinder head, next to oil filter housing)

The perfect upgrade for your connection between your thermostat and cylinder head. Designed using durable silicone and billet aluminum to greatly outlast the OE rubber and plastic combination.

Some of the weakest point of the cooling systems in BMW's can come down to the OE plastic fittings breaking down from the constant changes in temperature softening these plastic components. When this happens even simply moving the hose slightly could cause the fitting to crack causing the coolant to leak all over. The ECS design silicone hose with billet aluminum adapter retains OE fitment with superior strength to not only handle the performance, but stand up to the wear and tear of a daily driver.

Features: 

  • Manufactured from billet 6061-T6 with type III anodize for exceptional durability and corrosion resistance.

    • Much stronger part than OEM plastic

    • Will not become brittle and fatigue over time due thermal cycling.  This will prevent the part from breaking during removal and re-installation.

  • Constructed of 4-Ply reinforced silicone for improved durability over the failure prone OE rubber hose.
  • Flourosilicone lined internal layer for exceptional chemical resistance.
  • Silicone offers reduced thermal conductivity as well as improved resistance to ozone and UV degradation for improved performance and durability.
  • Follows OEM form for perfect fitment.
  • Utilizes OEM O-ring 11537545278 to ensure a proper seal.

The N5X family of engines marked the start of a new era for BMW. The all-new aluminum block powerplants featured a host of technical upgrades, aiding in power output, reliability, and performance. Among these technological advances is an external electronic water pump, which removed load from the engine's accessory drive and allowed for advanced pulse-width-modulated (PWM) control.

From factory, the N52's electronic water pump is limited to a measly 200W output—strong enough for daily driving, but lacking in performance applications. Recognizing this shortcoming, ECS engineers set out to create a high-flow water pump upgrade that doesn't break the bank. Their high-quality adapter wiring harness and bracket allow you to install a 400W N54 water pump without any modification, an effortless, yet effective upgrade that doubles the output of the factory water pump!

By increasing coolant flow capacity, the 400W pump improves heat extraction from the cylinder head and engine block during high-load operation. This added thermal headroom is particularly beneficial for modified engines, sustained aggressive driving, track use, or operation in elevated ambient temperatures where the factory pump can operate near its limits. Improved circulation helps maintain more stable coolant temperatures and reduces the risk of localized hot spots.

Features & Benefits:

Upgrades to the more powerful 400W N54 water pump for increased coolant flow and improved engine cooling efficiency Sealed adaptor harness ensures secure connections and optimal operation under demanding conditions The N54 pump's higher power output offers longer-lasting, more effective cooling compared to the stock N52 pump Design:

40A fused power wire safely handles the increased power demands of the N54 pump, providing consistent and stable performance Sealed and robust construction, designed to withstand heat and moisture, ensuring reliability in even the most challenging environments Plug-and-play compatibility is designed for easy integration with the N52 engine and N54 water pump, minimizing installation time and complexity Kit Contents:
