BMW Cooling System Parts & Accessories for BMW 4 Series F33 (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.

Water pipes and coolant hoses are essential for proper cooling. If they are cracked, they are going to need to be replaced as soon as possible to avoid overheating your engine. Wear is easy to see on these rubber hoses. Bulges, cracking, splitting at connections, and the loss of flexibility are usually big indicators that they are reaching the ends of their lives. Replace them whenever this wear is identified.

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 regularly, the plastic will become brittle and will often crack or break. You want to keep all the coolant in your vehicle in the cooling system to prevent overheating issues. If your tank has experienced damage such as cracking, nipples breaking off, or mounting point damage, you will need to replace it.

The factory B4x/B58 heat exchanger is not built to cater to the rigorous demands often associated with a modified build. The thin core is easily overwhelmed with IAT's rising dramatically once pushed beyond a few successive WOT pulls or even a few minutes at the track. This elevation in temperature gives way to the factory ECU fail safes pulling timing and reducing overall power in order to keep the system from overheating to the point of permanent damage. On an application where enjoyment is directly attributed to pushing the platform to its limits this constraint to cooling presents a challenge for the automotive enthusiast. The Dinan B4x/B58 heat exchanger for the F2x/F3x chassis assists in mitigating these issues with a more robust core (48mm thick Dinan core vs. 27mm thick OEM core) that wields 78% more heat transfer surface area for improved cooling capacity. The significant increase in core thickness requires unique "L" shaped end tanks to be incorporated as well, which also contributes to the overall thermal mass (ability to absorb, store, and release heat) improvement beyond the OEM setup. With up to a 15° IAT delta recorded over stock the Dinan heat exchanger is ready, and able, to assist in extending your vehicles ability to deliver maximum performance time and time again for your driving enjoyment! Features: Average of 8° reduction in IAT's with a maximum reduction of 15° over 15 successive WOT pulls Reduces the tendency to heat soak / go in to limp mode 48mm thick Dinan cooler vs. 27mm thick stock cooler 78% more cooling surface area and volume than stock 100% TIG welded and pressure tested Installation hardware included (inclusive of xDrive specific transmission oil cooler brackets) NOTE: Due to the enlarged core and unique "L" shaped endtanks minor modification to the plastic core stack shroud may be required with some factory configurations ( particularly those with the optional OEM hot climate heat exchanger). Consult the installation PDF for full documentation on what exactly that entails. (https://documents.dinancars.com/d780-0002.pdf)

Charge Air Cooler Expansion Tank - Rein | BMW F22/23, F3X B48/B46 B58 is an essential component that ensures proper coolant circulation in the charge air cooling system. Acting as a reservoir, this expansion tank allows coolant to expand and contract with temperature fluctuations, preventing excessive pressure buildup. Over time, plastic tanks can become brittle due to constant exposure to heat cycles, leading to cracks and leaks. A failing tank can cause coolant loss, reducing the efficiency of the charge air cooler and leading to increased intake temperatures, which negatively impact horsepower and engine performance. Rein offers a high-quality direct replacement designed for durability and a perfect fit on BMW F22, F23, and F3X models with B48, B46, and B58 engines.

  • Maintains proper coolant circulation within the charge air cooling system
  • Prevents excessive pressure buildup caused by temperature fluctuations
  • Durable construction resists cracking and leaks for long-lasting performance
  • Direct replacement for BMW F22, F23, and F3X models with B48, B46, and B58 engines
  • Helps maintain optimal intake air temperatures, preserving horsepower and efficiency
  • OE-quality fitment ensures hassle-free installation and reliable function

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.
