With all the rain and flooding from the last hurricane and Ivan getting ready to flood us twice as bad, how far could water rise up on the motor before drowning the motor.

I'm curious, there isn't any open ports other than intake air and exhaust, right. Could the motor be submerged using snorkles and perform during a emergency.

Someone try this and let me know

 

I've had water coming up over my hood before while driving and it never sputtered. Just took it slow and easy. I was just starting to get a little seepage into the cab when I made it through. Would I recommend this, NO!! I used to live in the Houston area and we had some pretty good floods there.

There is an opening up front for the air inlet. It is located under the passengers side headlight assy.

As long as the intake and exhaust aren't submerged it'll keep going. When you shut down, you risk replacing every elctrical component to get it going again. Even a teaspoon of water gets to your tranny clutches, you'll be taking it out. If water gets in the axles, change the fluid quickly too.

 

exhaust is fine under water just dont stall or turn the rig off. jiMMy

good way to find leaks too :-)

 

I thought I read somewhere that the injection pump could be damaged due to it "shrinking" on the outside or something like that?? just my .002

 

well most diff and transfer case vent hoses are at the bottom of the cab, and your engine oil breather is down there. not sure where the tranny vents. then the obvious exhaust and intake. Id still go through the puddle but realize you are going to have to check all the fluids.

 

SHARPMACHINE, I’ve read that too in either my owner’s manual or my factory service manual. Something about never let cool water hit a hot injection pump. Before I knew that, I pressure washed my engine while it was running, and luckily had no problems.

 

I've washed mine and didn't know this either. No problems yet luckily, but I also tried to keep the water away from the connections at the back of the pump, so this may have helped.

Serious off roaders run their vent tubes up to the engine compartment. You still have to consider the condition and how much you trust your seals to keep it out. I've had water in my diff from going through puddles (seals weren't the best) and it takes more than one oil change to get it all out. On the tranny you also have to trust your dipstick seal and shifter too. Remember the seals generally work best keeping fluid from passing in one direction. Just food for though, not meant to be preachy.

Great, now I find this stuff out. I just soak my motor twice a year with engine degreaser and then just soak it again with water to rinse it off. Cleans it up real nice. I don't think I have done that though when the motor was hot though. But I have never had a problem sprayin water all over the engine compartment. Started right back up and let it idle for a few minutes to dry it off.
