BMW F30 Radiator Cap FEBI (Coolant Reservoir Pressure Valve)

FEBI 36737 | Original German Quality | Optimal Pressure and Temperature Solution

⚠️ IMPORTANT BURN HAZARD AND PRESSURE WARNING:
  • Hot Engine Hazard: Attempting to open an old or new BMW F30 Radiator Cap while the engine is hot is STRICTLY prohibited! Boiling water and steam in the system can spray directly onto your face, causing severe burns. Only open the cap when the engine is completely cool (in the morning or at least 3 hours after shutdown).
  • Hose Burst Risk: This cap is not just a plug; it is also a precision pressure valve. A faulty BMW F30 Radiator Cap with a stuck spring mechanism that cannot release excess pressure can burst radiator hoses or split the expansion tank.

Imported specifically for BMW's legendary 3 Series F30 models, the FEBI brand BMW F30 Radiator Cap is now available! This mechanical valve creates a specific bar pressure in the system to raise the boiling point of the antifreeze coolant. Over time, the extreme hot-cold cycles can stretch the steel spring inside or melt the rubber O-ring seals. An old BMW F30 Radiator Cap that fails to maintain pressure and releases water as steam can cause the water to boil at much lower temperatures, leading to coolant loss and ultimately causing the engine to overheat and blow a gasket. To save your vehicle from these massive repair costs and roadside stress, you can reset the pressure in your cooling system with this brand new BMW F30 Radiator Cap manufactured with FEBI Bilstein quality, the original supplier of German automotive giants. This imported BMW F30 Radiator Cap comes with heat-resistant, pressure-resistant O-ring seals, completely sealing your expansion tank from the outside and keeping your engine's temperature gauge in the safe zone.

  • Prevents Boiling (Overheating): A brand new BMW F30 Radiator Cap keeps the water in the system at the ideal bar pressure, allowing the liquid to remain in liquid form up to 120-130 degrees without boiling.
  • Stops Coolant Loss: Thanks to its flawless O-ring (rubber seal) structure, it completely prevents the water in the expansion tank from evaporating and escaping into the atmosphere.
  • FEBI (German) Quality: Manufactured to original factory standards (OEM). Unlike aftermarket caps, it opens the valve when the specified bar value is exceeded, protecting the system from bursting.
  • Easy Installation: You can easily replace the old cap by turning it off by hand when the engine is completely cool, without going to any mechanic.

Frequently Asked Questions (FAQ)

My car keeps giving warnings and I add water once a month. We haven't seen any leaks in the system. Can I solve the coolant loss just by buying this BMW F30 Radiator Cap? If there are no physical leaks in your radiator, hoses, or water pump, the most insidious cause of coolant loss is a faulty radiator cap. Since the cap cannot maintain pressure, water evaporates as steam when the engine is hot, and you cannot see where the leak is. Since replacing it is the most cost-effective solution, starting with renewing the cap with original FEBI quality is always the best industrial rule for diagnosing coolant loss.
Should I apply extra liquid sealant or tape under the new cap? Absolutely not! FEBI caps have specially manufactured rubber O-ring seals that fit precisely into the threads and mouth of the expansion tank. Applying silicone or Teflon tape from the outside disrupts the air release (valve) function of the system and can cause the hoses to burst due to pressure. Simply hand-tightening the cap is sufficient.
