Forge water radiator for Renault Megane RS250

Forge Motorsport all alloy radiator for the Megane RS250/265/275.

With the known coolant temperature issues that are attributed to the original fitment radiator, this is the only real solution. The stock Renault radiator has a major design flaw in that the inlet and outlet are in a straight line across the core. At high engine rpm, when you need the most cooling, the maximum flow is straight across the core, missing out about 75% of the volume. Worse still, the 25% of the core with good flow is directly behind the crash bar and gets no direct airflow.

Forge engineers have maximised the surface area and utilised a high efficiency radiator core with a unique flow enhancement, to ensure that the coolant passes evenly across the entire core, and that the area of restricted airflow (behind the crash bumper) is taken into account.
Independent tests have revealed a 20°C reduction in maximum water temperatures, as well as a 15°C drop in oil temperatures on the track.
