How deep in the water?

[BRETTLSMO]

2019 Z71 LT stock.

How deep in the water can I back my Tahoe?
Going to the lake and boat ramp is WAY FLAT....
I am guessing that i will have back down the ramp until my rear axle is over the top.

Last time I used this ramp I had a truck that I extended the vents into the engine bay.

So the question is? How deep can these stock Tahoe 2015-2020 get into the water?

Thanks.

As an avid watcher of YouTube boat ramp fails, I ask you to please not end up there. However, you're asking a great question that I'd love to know the answer too as well. Subscribed

As deep as you are willing to pay to fix! The old rule used to be up to the spark plugs deep, then boots got better and it became keep top of motor dry. Now I think halfway up the tires is probably going to cost you sooner or later. Too many wires. Dunking the rear in fresh clean water still have to check for water in oil. Axle seals or vent line under.

Well, the 2019 owner's manual says not drive into water deeper than the hubs, axle or exhaust pipe. The rear axle is sealed and there is a vent tube that exits several inches above the rear differential. Is yours a 4x4 with All-Terrain tires? I'd sure be leery about backing down that deep on a slimy, algae covered ramp even with my All-Terrains and engaged in 4LO! Wouldn't want to wind up on youtube!

Don't be this guy!:

If you put the rear axle under water you should check the rear diff fluid, the vent tubes can crack over the years causing them to act like a straw and draw water into the diff, happens more than you think.

Personally, I wouldn’t want to get the vent solenoid wet. There are enough issues with them as it is.

Not to mention you could slip off the back edge of the ramp and then the party is really over....
Find a longer trailer tongue...

Something about the narration of these videos really grind my gears. But at the same time awkward silence is boring

Dont forget about the Air Compressor (if equipped)!
