Radiator and Condenser Fans

There are many different electric fans available to perform many duties. The fans we sell are used to supplement the air flow through the condenser. We have a small assortment of 16″ fans used for Radiator cooling. All fans are reversible unless noted.

Every vehicle with air conditioning needs a fan on the radiator to pull the air through the condenser and radiator.  Fan blades, electric fans, and shrouds are the most critical part of an a/c system.  If the fan is not moving enough air the a/c will not be able to operate effectively.  Every vehicle should have an electric fan, or a mechanical fan if a/c is installed.

The best setup for any vehicle is to use a fan clutch with a steel blade fan, and a fan shroud.  A fan shroud can be used incorrectly.  The fan blades on the engine should sit half in the shroud and half out of the shroud.  If your fan is all the way in the shroud or on the outside of the shroud it will not pull air through, and get rid of the air from the radiator area.  If you have a fan shroud, and a fan blade that is made of a flimsy aluminum you may experience problems with the a/c not performing also.  Our best guess is that the fan blades flatten out while the vehicles are driving at higher RPMs.  If the blade flattens out it will cause the air to be stopped by the fan leaving hot air in the area of the condenser and radiator. 

An easy fix to help an insufficient fan and shroud setup is an auxiliary electric fan.  The electric fan can be mounted on the front of the condenser to help move.  If you add to many electric fans it may have the same effect as the flimsy aluminum fan blade.  The goal of a fan is to move air, not restrict it.  If you wish to use an electric fan for the cooling fan be sure to purchase a good quality electric fan such as Maradyne.  Good quality fans are normally tested under all conditions, have better components to avoid failure, and move more air (higher CFM).

If your vehicle does not have room for a fan blade, fan clutch, and fan shroud you should build a “wall” around the area between the condenser and the radiator to form a tunnel.  This will force air through both parts without losing air in the middle or pulling air from in between the condenser and radiator.  The most important thing to remember is that air will always flow the path of least resistance.  Be sure make the air flow through the radiator and condenser and not around it.

If you are using an electric fan a relay, and a thermostat should be used.  We also offer trinary switches for auxiliary fans.  The relay will protect your vehicles electrical system from being overwhelmed, and the thermostat will turn the fan on and off so you do not have worry about remembering.   We offer directions on the website for relay wiring, and all the thermostats we sell come with directions.
