An all alloy radiator for the Megane 3RS 250, 265 & 275 Models.
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
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.
Being confident in their design, they sent this for independent testing and
were pleased to hear that they had achieved a reduction of 20Â°C in peak
water temperatures,and also a drop of 15 Â°C in oil temperatures on the
Please note, this will not fit with the Standard Intercooler & Wagner intercooler.
