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.

The auxiliary fan in your vehicle serves an extremely important role. When your car reaches temperatures that may be hazardous to your engine, the auxiliary fan moves air through the radiator to provide better cooling. Usually activated during times of stationary vehicle operation, it supplements the air usually driven through the radiator by driving down the road. If your vehicle is getting too hot during traffic or at stop lights, your auxiliary fans are probably faulty. Replace yours with this piece from ACM to restore the factory cooling in your vehicle and prevent catastrophic damage to your engine. Even if your fans are still operational but the blades are damaged or cracked, replacement is the only solution.

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:

The coolant expansion tank in your vehicle gives additional fluid a place to go after expansion and contraction from temperature change. 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.

Over time, rubber hoses and plastic coolant flanges can become brittle due to numerous heat cycles. This often leads to cracks and coolant leaks on the front side of the engine. Additionally, the two o-rings that seal this hose to the cylinder head and the water pump housing can flatten, leading to leaks when reinstalled. When servicing your cooling system, it is advised to replace this hose to prevent leaks and potential overheating.

As most 335 owners have discovered, the cooling system is vital to maintaining high levels of boost. The car's sophisticated electronics wisely shut down and limit boost when temperatures are elevated enough to do potential harm. Don't short-change your cooling system or performance on the street or the track! Where the stock radiator suffers is in capacity, which is why BMW also sells an additional radiator and other cooling upgrades with their Performance packages. This radiator for the E90/E92 335 and E82 135/1M is a larger 40mm core (2mm thicker than stock) for additional capacity and bulletproof cooling. It fits in the stock location, with the stock shroud and fan (some plastic trimming may be necessary), maximizing the available space to dedicate to fluid capacity and surface area. Having a greater capacity means less saturation time for the cooling fluid which leads to more consistent engine temperatures, reducing the possibility of limp mode condition and reducing wear and tear on other cooling components such as the water pump and thermostat. If you're looking for the most complete and unbeatable radiator solution for your E9X, this is the best we have seen. Not only is this radiator larger, but it's also designed with the stresses of motorsports in mind. The cooling vanes use a unique oven-brazed bonding technology that will not fatigue and crack like epoxyed construction. Aircraft-grade aluminum is used for the tanks and frame, which are TIG-welded for superior strength. This radiator is a direct replacement for the stock E9X radiator, with all of the same hose locations and fittings as the original radiator. Because of the extra depth required between the radiator and engine, extra care will be needed when installed with upgraded intercoolers, intake piping, and oil coolers. This aluminum radiator is a replacement for the stock BMW radiator 17 11 7 558 480 and fits the 135i and 335i/xi (automatic transmission only). This item fits the following BMWs: 2008-2012 E82 BMW 135i 1M Coupe - with auto transmission only 2006-2011 E90 BMW 335i 335xi 335i xDrive - Sedan - with auto transmission only 2007-2013 E92 BMW 335i 335is 335xi 335i xDrive - Coupe - with auto transmission only 2007-2013 E93 BMW 335i - Convertible - with auto transmission only 2009+ Z4 BMW Z4 28i Z4 35i WARNING!

This is the Genuine BMW electric water pump for F30 F32 F22 models with the N55 6 cylinder turbo engine. The electric water pumps on older N54 and N55 engines tended to be failure prone.

The N55 water pump is electrically driven and varies output based on instructions from the engine computer. Under the best circumstances the pump drives only as much coolant as needed and will shut down or activate as load and performance demands change (combustion chamber temperatures are dynamically changed based on economy, normal, and performance demands). The pump can also run when the car is off to reduce heat soak in the engine and turbo(s). The water pump is now a factor in how much power and fuel economy your car is producing, making it all the more critical to replace during normal maintenance. If a fault or excessive temperature is reached, the dash cluster will display a yellow or red water temp icon depending on the severity of the condition. The car's electronics will begin shutting down various systems in the car to divert more resources to the cooling system. This can include reducing power output and activating 'limp mode'.

The best way to avoid problems and system failures? Preventative maintenance and overhaul of the cooling system, starting with the water pump (and thermostat).

NOTE: Not for cars with M Sports Package - option code P337A

Full hose kit includes: Upper Radiator hose Lower Radiator hose Cylinder head outlet hose (Mickey Mouse hose, this hose is notorious for breaking when removed) Upper vent hose (this hose is also notorious for breaking as stock the center is plastic that crumbles when moved) Water pump inlet hose (Horse Shoe hose)
