Overview

To reduce the risk of overheating, the cooling capacity of the typical DB4 or early V8 needs significant upgrading. Not only does this need an improved and denser radiator matrix, but it is also essential to increase airflow through the radiator when the car is stationary or slow moving. On the latter point, the preferred answer is fit one or two electric thermostatically controlled fans.

The upgrade of cooling radiator and specification of electric fans depends on the climate where the car owner expects the car to be used and are best specified individually.

Another aid to engine cooling would be the fitting of a modern aluminium oil cooler.
