BMW 3 Series M4, G20, G22, G42M Radiator – High-Performance Cooling System Replacement

Protect your turbocharged and high-output engine with this BMW 3 Series M4, G20, G22, G42M radiator, designed for the latest generations of the 3-Series, 4-Series, and M models. These vehicles rely on efficient cooling to handle higher boost pressures, stronger acceleration, and daily driving demands. When the radiator becomes blocked, cracked, or begins leaking, engine temperature rises quickly. Replacing it restores stable cooling performance and prevents long-term engine damage.

This radiator follows the correct factory dimensions for the G20 3-Series, G22 4-Series, and G42 M models. It mounts directly to the original points and connects smoothly to the cooling hoses, fan assembly, and temperature sensors. Because the layout matches the factory design, installation is simple for workshops. Once installed, the radiator provides consistent coolant flow and efficient heat transfer.

The strong aluminium core and reinforced tanks handle high pressure and elevated temperatures produced by engines such as the B48, B58, and S58. Additionally, the radiator supports proper airflow to related components, including intercoolers, transmission coolers, and auxiliary radiators found in M-Performance variants. As a result, the engine maintains stable temperature during city driving, long-distance travel, and spirited acceleration.

A replacement radiator is ideal for vehicles showing coolant loss, overheating warnings, cracked tanks, temperature spikes, or poor cooling efficiency. Many owners upgrade or replace the radiator when refreshing the cooling system, repairing front-end damage, or preparing the car for long-term reliability.

If you are unsure which radiator your vehicle uses—standard, M Sport, or high-performance M variant—send your VIN number. We will confirm the exact radiator for your G20, G22, M4, or G42M model.
