Water terrains are altogether different compared to other 4wd tracks as it requires thorough planning, stability, and utmost control. The danger of damaging your 4wd is high. Read on to learn to avoid those dangers. And make the next time you are crossing water in your 4WD a fun experience.
Initial planning & parts to look for on your 4wd
At first ‘walk’ through the crossing to gauge the depth, feel for holes and determine the traction. This provides time to your differentials, gearbox and transfer case to cool down before really hitting the water which is vital.
The radiator fan should be checked with the engine turned off. If your 4×4 runs on the petrol engine consider using a moderate dose of CRC or similar water repellent. Diesel engine vehicles are not that vulnerable to water damage and minimise the flow of water that gets into the engine bay. Be aware of where your air intake is if you don’t have a snorkel. Do not go deeper than that level because water will cause terminal damage to your engine and it takes plenty of money to repair.
Crossing waters is like blind driving and all about feeling what is beneath the wheels & how they are responding. Slow and steady is the key here. Maintain a steady rhythm (commonly low 1 or low 2 on your 4wd) while keeping control over the vehicle. After crossing the terrain pull over on a slope and let the water drain away. Meanwhile, complete your post-crossing inspection on the differential, gearbox and transfer case oils for water contamination.
Follow these guidelines and making crossing water in your 4WD a safe and fun experience.
