I put my JLX Soft top Vitara across the Wollondilly river, at the nudist resort, and the water, was over my bonnet, and 4 inches up my windows, yes got some water in the back, but I had no snorkel, the back wheels were floating, and luckiiy in 4 wd the front wheels were touching the boulders in the water, due to engine weight, and managed to cross this river, in those conditions, 3 times in the same day. I got no water, in thru the air intake, nor into the engine. My later Vitara a 2001 mod, was set up better for water crossings but it also didn't have a snorkel, and did drive with water over the bonnet on numerous times, and also had the diff breathers, set up from factory, with the extend lines, and had one way valves, on the end of those lines, that let the air out but not water in. Those lines where on the diffs, the transmission, and the transfer case. Never should have sold that vitara, but the daughter wanted it badly to set up for serious off roading, so parted with it.
