Warning: Installation of accessories should only be undertaken by those with mechanical knowledge and are familiar with working on
vehicles. Always use eye protection (goggles, safety glasses or shield). Park the vehicle in a well lit area, on level ground and apply the
parking brake. Only work on a cold vehicle that has been sitting overnight, failure to do so will result in severe burns and injury. Before starting
the vehicle, make sure no tools or any other items are left under hood that could interfere with or be drawn into moving parts of the engine.
Failure to follow instructions can lead to severe damage and personal injury.
TROUBLE SHOOTING Q&A
Q: Why doesn’t the fan turn on automatically?
A: 1. Check all connectors to make sure contacts are crimped correctly.
2. Check the Ground connection to make sure all paint is sanded off and you are getting a metal to metal contact.
3. Check the 20 Amp Fuse Holder to make sure the fuse is good and is securely in place.
Q: Why does the electric fan run after the engine is turned off?
A: Check the ignition wire to make sure this is connected to a switched ignition source and not a constant power source.
