4wd Tips and Tricks: Water Crossings

Know Exactly  What to do Before Attempting Water Crossings

Don’t go into this advanced maneuver without first knowing what to expect and what you should do if it goes wrong

  • If you are hesitant or are not sure of the crossing, do not attempt it on your own. Have another person in a vehicle fitted with a winch to come with you in the instance where your engine stops mid-crossing, or you get stuck and you need to be rescued.
  • Check the crossing including the exit before you plunge in.
  • Water depths of up to 30cm can be handled fairly easily but will depend on the type of bottom and the current flow. Soft sand and/or a strong current can make even a shallow crossing a problem. A snorkel for deeper water may be required.
  • Spray electrical components with WD40 before entering the water.
  • Loosen the fan belt unless it has an auto clutch (auto clutch will still spin at higher RPM). A spinning fan can spray water onto the electrics.
  • In deeper water (over 30cm) remove fan belt and fit blind to help create a bow wave.
  • Keep speed down, but fast enough to create a bow wave – low second gear is best.
  • Do not disengage clutch or change gears.
  • Keep the engine running, even if you stop. If the engine does stop, DO NOT restart it. Winch or snatch out.
  • After crossing, dry your brakes out. Check all oils for contamination if you’ve been driving regular, deep crossings, or you’ve become stuck.
