An all alloy radiator for the Toyota Caldina GT4
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.
