87-93 Fan Wiring - Factory Five Racing MK4 ROADSTER Assembly Manual

Run the tube next to the 4" main rail and under the steering rack to the radiator. Route the lower tube
with enough slack to be able to adjust the radiator for the nose aluminum.
Make sure that the lower hose is not hanging down. If necessary, zip tie the hose to the frame.
Mark the tube where it needs to be cut so that the tube will just touch the attaching location.
Remove the tube/hose assembly from the vehicle.
Cut the tube using a hack saw or if available a cut-off wheel. If necessary clean the end up with tin
snips or a grinder.
Shake and blow the tube out so that no metal pieces are in the tube.
Remount the tube assembly and tighten the hose clamps on the mount locations.

After running the car for the first time once coolant is added and while the system is still warm,
retighten the hose clamps used on the cooling system.
