Radiator Cooling suggestions

SouthArk370Z

Unless you can come up with a better coolant, your choices are limited to more surface area and more air flow.

It's probably going to take more than one mod to cool you down but I think theDreamer has the best single fix - bigger, more efficient fans. The shroud is a critical component and need to be carefully matched to the fan. Placement of the fan in the shroud is also critical.

Can the undertray be modified to allow more air to escape from the engine compartment?

Edit: Have you checked flow through the cooling system? It can cause overheating if the flow is too high (not enough time in the radiator) or low (too much time in the engine).
