BMW Coolant Expansion Tanks for BMW 4 Series F32 (2014+)

Clear BMW chassis

On certain models, namely E36, E46, and E90, the factory BMW expansion tank is prone to either breaking at connection points or blowing apart altogether. If you're starting to feel like your expansion tank is on borrowed time, it's probably time to replace with either a direct OE replacement, or strengthen your cooling setup with an aluminum expansion tank - we offer numerous performance upgrades for your expansion tank. Especially if you're someone who likes to track your BMW, we recommend upgrading your expansion tank to avoid ruining your track day.

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.

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

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.

We have found that the expansion tanks should be replaced based on age as well as condition. Expansion tanks seem to have a lifespan of fewer than six to eight years before they show signs of fatigue and wear. Pre-emptively replacing the expansion tank as part of an overall maintenance plan can prevent you from getting stranded from a sudden failure later on.
