And answer to the second part is - it is as high as it could be before water gets to the exaust and reaches the bottom of the radiator fan. After that - fan start spraying all vital eletrical parts, and clogged exaust can stall the engine.
With regard to the fan, my concern would be that the blades are angled such that impact with water will drive them into the radiator. <p>You could disconnect the fan and get one of those Land Rover snorkels that sticks up above the roofline. <sarcasm><p>Jack
You also have to be careful of any drivetrain parts that may have vents on them. I know on my Jeep I have pressure vents on both differentials and the transfer case. If there are vents on the drivetrain components and you submerge them, you can get water in with your gear oil which would be bad! I imagine the 18in spec protects not only the fan but any drivetrain vents as well.

The ABS sensor is likely a fully potted, sealed sensor, reading cast in place ridges or slots in the rotating portion of the hub. While the ABS may not function correctly underwater <Grin> it should be fine when it comes up for air.<p>jack
Better to leave the water crossings to boats...<p>A good friend took his Jeep Cherokee across a "small creek" a few years back. Well, it looked shallow until his 4,000-pound Jeep hit the bottom silt and sunk to water half up the doors! He opened the door to crawl on the roof (while water poured through the cabin) to call for help. Of course, he didn't shut the engine off in time and it was a mess...<p>I always let another nut cross water right in front of me. I don't want to look dumb. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/wink.gif" BORDER="0">
You could caulk the car shut, and float it across. Or maybe you could hire an Indian to help you cross it. That always seemed to work the best. My wagon always tipped over when I tried to float it, and the ferry was never around.<p>Mind you, I only accomplished this in Oregon Trail a long time ago, but hey, the old conestoga wagon sure looks like an SUV doesn't it? Whatever you do, don't try to ford the water if it's deeper than around 3 feet. I lost my last pair of underwear that way... <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/frown.gif" BORDER="0">
I crossed a gravel bottom creek that I'm quite sure was 16 to 18" deep and flowing fairly well. I wouldn't normally have done it, except it was on a road where there was no choice and it appeared everyone else did it too. We had no problem, although I was told later than crossing gravel bottom creeks can tear up your nice wheels. We didn't notice any damage.<p>Seeing the other post, as a point of interest, I also had a couple friends that liked to drive their jeep and Toyota PU truck down creek beds for kicks. On bedrock it's just fine, except every now and then there are deep holes and the one guy in the Toyota managed to drive into one. The Jeep was able to get him out, and towed him home. A terrible mistake was then made by the guy being towed. He tried to jump start the motor, and since it had water inside the piston, it blew a hole right out the side of the motor block. Ouch! (Hey ma, watch this! BANG !) <p>Mr. P
