How Deep of Water Can a 4runner Drive Through?

A 4runner can ford through water that is up to its axle height. However, it is not advisable to drive through water that is deeper than this as it can substantially damage the engine. When fording through water, it is important to keep the engine speed low in order to prevent water from being sucked into the air intake. If water does enter the air intake, it can cause the engine to hydrolock, which can result in severe engine damage. In addition, deep water can cause the brakes to lose effectiveness, so it is important to use them lightly ifgment necessary when exiting the water.
