Default How Deep Can You Go?

How deep into a puddle could you go before you start damaging your vehicle? I know you as long you dont get into the air intake it should be fine, but what about other components underneath? When my blazer does see water/mud its normally just bombing through a puddle on a trail real quick, but during one longer set of puddles it started a high pitched, what almost sounded like an alarm which prompted me to question if i should continue

What you heard was probably just belt squeal from it getting wet and muddy.

If you're going to be going thru the deep stuff you'll want to reroute your vent tubes to higher ground to keep the water out of your differentials, tranny, and t-case. It's an easy job and hardly costs anything..But it could save you a ton of money. Fortunately most of the wiring connectors on our trucks have a rubber seal to keep water out, but taking apart your starter connections, battery/ground connections and coating them with dielectric grease is pretty important as well. (I also do my spark plug wires).

Technically any water is a risk, but most connections and systems have seals to try and prevent water and debris from entering. A reasonable rule of thumb is on a stock truck if the water gets any higher than your front bumper when your truck is level you're at risk of getting water into areas where it can have negative effects.

Vacuumn hose(as long as it's not silicone), washer fluid hose, or fuel hose will work. Vacuumn or washer fluid hoses are easier to work with because they're thinner walled... Probly cheaper also.

If you're doing a fuel system vent make sure it's fuel rated hose. You won't need to worry about this because you have a closed evap system, but just wanted to make note of that.
