Turbo-Flex Electric Fans are designed to assist belt-driven fans when additional cooling is required, to replace factory electric fans for equal or better air flow at a lower cost, or to replace the factory driven fan for improved engine performance and better gas mileage. All Turbo-Flex electric fans are pre-assembled and shipped as "pullers."
In choosing an electric fan for primary cooling, four cylinder engines generally require 1,600 cubic feet per minute (CFM) minimum. Six cylinder engines generally require 2,000 CFM minimum, small cubic inch eight cylinder engines require 3,000 CFM and large cubic inch eight cylinder engines require a minimum of 4,500 CFM. Recommendations are based on stock engines and regular driving conditions. CFM estimates are based on the electric fan mounted behind the radiator in a "pulling" configuration. Electric fans mounted in front of the radiator, in a "pushing" configuration, are only 80% as effective.
Turbo-Flex Standard Electric Fans feature high-strength, glass-filled polypropylene blade and shroud assemblies. Straight blade design flows substantially more air than spiral blade designs. The low profile configuration is ideal for vehicles with limited space. Standard electric fans have multiple locations to fit almost any application.
