When ordering an electric fan here are some things to consider.
1. What are the make, model and year of the vehicle?
2. Will the vehicle be used to drive on the street, race, or off roading?
3. Will you replace the engine fan with an electric fan or do you
want a pusher fan while still using the engine fan?
* If puller fan is to replace engine fan, you need to know the distance
(in inches) from the water pump to the radiator core. When using
only an electric fan, use 3 3/8" thick x 16" whenever possible or use
the Sidewinder Electric Fan Kit.
4. What is the width and height (in inches) of the radiator core (not
including tanks)? ____" W x ____" H
5. Is the radiator a cross flow (tanks side by side) or down flow (tanks on top and bottom)? |
Pusher Fan
Pusher fans with straight blades must be spaced out 1⁄4" from
core or fan mount bars. Pusher fans that go onto AC condensers can be attached with plastic ties and cut off at the condenser.
IMPORTANT: Do not put plastic ties through the radiator, as it will cause the radiator to leak in time.
Pusher fans should be the same diameter or smaller than the AC
condenser. If they are larger the air will pass through the open area.
For either a pusher or puller fan, one large fan (14" - 16") typically
works better than two small fans (10" or smaller). If you are able to
use two fans (11" or larger), two generally work better than using
only one large fan. When the pusher fan is a helper, one (11" or larger)
fan will work best, or you can use two (10" or smaller) fans if you have room. When a pusher fan is the only fan being used, select a fan or fans that will cover up as much of the core as possible. |
