BMW Cooling System Parts & Accessories for BMW 4 Series F32 (2014+)

Clear BMW chassis

Please ensure your correct model is selected

The cooling system is arguably the weakest point in numerous BMWs. If you drive an aging BMW or plan on taking your car to the track like we do, we recommend beefing up your cooling system before going to the track. Generally, the main components in your cooling system that are prone to failure include the following: expansion tank, factory hoses, water pump, thermostat, fan (especially if your vehicle comes factory with a clutch fan), and radiator. Factory BMW expansion tanks are plastic and prone to either breaking off at connection points or combusting. As factory rubber hoses age they either crack or break over time - we offer silicone cooling hose upgrades for most applications to avoid future failures. If you have an older vehicle, your water pump likely comes from the factory with a plastic impeller - we offer upgraded water pumps with metal impellers that are far more reliable. Newer model BMWs utilize electric water pumps - BMW spent millions of dollars engineering these water pumps, but they fail so often that we recommend replacing at 60,000 mile service intervals to avoid being stranded on the side of the road. In terms of thermostats, we offer various upgraded thermostats for racing applications. If your BMW utilizes a clutch fan from the factory, we have several options available in terms of universal electric fans - we recommend replacing these to avoid sending brittle plastic fan blades through your hood. For radiators, we recommend swapping out your radiator for one that does not use plastic connection points like your factory radiator.

**** DOES NOT INCLUDE HARDWARE ****** Hardware - ES4772301 The N55 engine is no stranger to oil cooling problems, that�s why we recommend installing the MSL Oil Thermostat. The standard oil thermostat will reach around 120 degrees Celsius with a normal driving style. The MSL Oil Thermostat will open at a lower temperature than the standard oil thermostat (at 85 degrees Celsius) and will keep the temperature stable between 95 and 105 degrees Celsius. Installing the MSL thermostat ensures a cooler oil temperature which will result in more stable performance, but above all this improves the reliability of the engine. It is recommended to install the thermostat, especially for cars that are tuned. The Thermostat is plug-and-play and made out of a solid block of high-grade aluminum at our own facility. It is equipped with a real thermostat, not an always open solution. The oil will still reach the operating temperature at the same time as a stock thermostat Features Include: 20�C/68F Lower Than Stock Rock Solid Housing - CNC machined housing. Real Thermostat - Equipped with a real thermostat, not an always open solution. For use in hot and cold climates Quick Installation - Takes only 30 minutes to install.

Your charge air cooler's coolant expansion tank acts as a reservoir, housing extra coolant, and gives fluid a place to go after expansion and contraction from temperature change. Because the plastic tank is subjected to regular temperature changes, the plastic can become brittle over time and will often crack or break. If your tank is leaking and you lose too much coolant, your charge air cooler will not function properly and your air intake temperatures will begin to rise, reducing horsepower and efficiency. If your tank has experienced damage such as cracking, nipples breaking off, or mounting point damage, you will need to replace it.

These caps come in three color options, so there is always a color that will work for you! Black with Billet Silver, Black with Blue, and the Stealth series (all black).

But our team cares about proper function just as much as we care about the appearance of every product we design. For pressure relief, our caps incorporate the OEM internals, so you get all the functionality of the original caps, ensuring a safe and reliable system in place. These caps offer superior style and performance-grade components that guarantee a reliable fit every time. Durable billet aluminum construction provides long-lasting protection and dependability that will upgrade your engine bay for years to come. PLEASE NOTE: These do require assembly and swapping the pressure relief valves from your old caps to your new billet caps.

If your water pump is leaking coolant, there is a good chance one of the seals has failed. This is especially common when your coolant level gets too low and your BMW's water pump runs without coolant. The water pump shaft seal can fail as it gets too hot and you will begin to notice coolant dripping from the weep hole found at the bottom of your pump. We recommend replacing the whole pump to ensure your BMW stays cool for many more years! This kit includes the basic parts necessary to replace your water pump: GEBA Mechanical Pump with an upgraded metal impeller Elring Water Pump Gasket Genuine BMW Water Pump Bolts (x6) Don't forget to pick up a gallon of BMW coolant as well to top your system back off once you have completed your pump installation! Servicing your accessory belt and tensioner is also great to do at this time as the belt must be removed before replacing your pump.

Water Pump And Thermostat Kit - BMW N55 F Chassis

Ensure optimal engine cooling and performance with this high-quality Water Pump And Thermostat Kit - BMW N55 F Chassis. In the mid-2000s, BMW introduced electronically controlled water pumps and thermostats for better temperature regulation and efficiency. However, these components tend to have a shorter lifespan compared to traditional mechanical designs, often failing before BMW’s recommended 80,000-mile service interval.

This complete kit from Turner Motorsport includes premium-quality components that match OEM specifications, providing reliable and efficient cooling system performance. Maintaining a properly functioning cooling system helps prevent overheating, enhances efficiency, and extends engine life.

Signs Your Water Pump and Thermostat May Need Replacement:

  • Engine overheating or failing to reach operating temperature
  • Water pump running intermittently or erratically
  • Cooling fans operating at maximum output
  • Engine fault codes, including 20A804

Upgrade your BMW N55 F Chassis cooling system with this all-in-one kit for worry-free performance and longevity.

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 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.

When it comes to your temperature gauge on your instrument cluster your thermostat plays a large role in where that temperature needle ends up. There are many cases where the vehicle will run a bit cool according to that gauge, oftentimes meaning the thermostat has failed and is stuck open allowing coolant to continuously circulate. The other more damaging side is when it closes shut and keeps the engine from cooling down properly. All vehicles are designed to operate in an ideal temperature range for the ultimate efficiency, life, and performance.

The OE plastic connector is a frequent failure point due to brittleness and cracking caused by repeated thermal cycling and hydrolysis. Hydrolysis, the breakdown of plastic or rubber by water exposure, weakens the structure over time, leading to failure. To combat these issues, Rein’s upgraded connectors are constructed from high-strength aluminum, eliminating the vulnerabilities of plastic connectors and ensuring long-term durability.
