Just to be sure...wading the diesel

Hello all,
I'm pretty sure it's evident that the DEF injector makes the Jeep a puddle hater, but has anyone done any creek crossings or wading of water at any level and survived? Living in the Northeast we like to get some serious rains, and in my past rides I welcomed washing off the underbelly on occasion.

Seeing that Joaquin is about to hit us hard am I simply asking for trouble driving on wet, semi flooded conditions in the diesel? Is it pretty much a guarantee that if that wiring/injector gets wet it's game over?

I've done a couple of creek crossings with Dom's injector plate installed. No problems.

Unprotected (ie: no plate) it is not so much a question of wet as it is applied force. For example, I believe that it should survive a gingerly entry/exit into standing water. Where it fails utterly and catastrophically is when water is sprayed onto the affected area, so like 96.38% of the time.

I broke the injector driving on roads with about half an inch of water on them (South Florida Deluge), and post Dom's Plate, have not had an issue in same/worse conditions.

Does is also apply to the "fix" Jeep made for later 2015 models? Mine is finally built and should be here a a couple of weeks. Just wondering if I need to get the Dom armor plate for the DEF.
Thanks

I don't know the specifics of the 2015 "fix", but if it is anything like the recall "fix", then get the plate. Zip ties to the DEF tubing adds some stability, but the weak point is the injector itself sticking down (not up!) towards the front passenger wheel well...

No problems hitting deep standing water - but would not attempt it without Dom's DEF plate.

Re: Just to be sure...wading the diesel

I live in South Tampa Bay area and did not know anything about the DEF injector untill last week when I joined here. It rains like hell here and I am constantly driving through some serious wetness and never had a problem(obviously). Now I don't have 4wd so I am not worried about ripping it out offroad but I can personally tell you rain water is not the enemy.

Deep standing water taken at speed will break off the injector - it's only a matter of time....

In addition to Dom's plate we found this that will also give peace of mind and protect the entire harness. It works with the def plate. Found it doing a google search of "def injector shield" company or site called shield productions

I managed to take mine through about 3-4 feet of water by accident. Did just fine. I needed to change my underwear after but I had no damage
