Is a Snorkel Necessary?

In looking at lots of builds, snorkels seem to be a rarity. Never gave them a thought.

Then I saw this video, which should start at 5:18:


Are snorkel's necessary? Should that be planned as part of the build?

Imho snorkels encourage stupidity. A snorkel does not make a Jeep a boat. Raise your breather tubes, stay out of deep water, and service your fluids regularly.

Though they are originally designed for water crossings in Africa and Australia (apparently common), I personally think the most compelling reason to have one (and perhaps the only reason) is to be able to mount a pre-filter that catches dust.

Out here in the West our trails tend to be EXTREMELY dusty during dry seasons (which is most of the time). I typically come home from a trip with a solid layer of dust caking EVERYTHING. I will change my air filter element every spring for this reason (even though I only put like 5,000 miles a year on my Jeep) and I'm seriously considering a snorkel just so I can run a pre-filter for such trips.

Driving through deep water is honestly something that affects a lot more than just the engine intake. You have to think through a lot of things (axles, bearings, diffs, transfer case, etc.) Anything with oil in it that gets water introduced will create what I call "gear oil mayonnaise" - a whipped emulsion that will no longer perform its duty of lubricating and cooling components. Those components will then be much more susceptible to failure. I've personally had this happen to a transfer case in a CJ5 that I ended up having to rebuild.

Is it Necessary? Depends on what you have in mind for your jeep. Reference my sig.

When i was younger, I played in the Pine Barrens where there is a lot of dark water. Can't see the bottom, and some have deep holes. Had old Ford pickups then with points and none of the computerized stuff. Enter the water slowly and drive slowly, and if it starts to get deeper than you like, back out.
As mentioned, if your playing in deep water, there are many other considerations. Axle breather tubes, oil and auto tranny dip sticks, and these days computers, electric fans, etc.. Used to have to change out the U-joints often. I wouldn't purposely rely on a snorkel to protect the engine, but in one of those unexpected situations, you may be glad you have it.

It is very useful to suggest abuse and that all that buyers should avoid this vehicle

Snorkels are/were very functional on diesel submarines. Jeeps not so much. If your in over your head your in way to deep.

In order to achieve peak efficiency, you need to entirely enclose your windshield with a snorkel, farm jack and 900 LED light bar.

Better to have and not need .. I have been on trails where the front end has dropped in a hole where water has come over the hood. Those instances are NOT planned and those are the situations that will take you out of the game. So it depends where you wheel. Some guys take chances on the rocks, some in the bush.
I always say be safe or be sorry.

personally I think for dusty conditions they are pretty valuable especially with a pre-filter. You go to Moab and it is amazing how much dust and sand are stirred up.

For a 3.8, yes. A 3.6? Nope, not needed. I off-road in the everglades where boats are more useful than Jeeps.

Lol and what makes you say that?

The factory intake is in the same place for both the 3.8 and 3.6.

And yes I know 2 people personally that have destroyed their 3.6 from water ingestion.

I've had water over the hood several times, no issues. Only the idiots who charge the water at high speed seem to hydrolock.

A vehicle with that much electronics that has been submerged (intentionally) is not something any rational person would consider buying

It all depends on what types of trails you run. For example, I run lots of very tight New England trails. If I had a snorkel, it would likely get torn off. Luckily, our trails around here are slow speed, typically not too much dust. Water crossing depths are known or checked, and I don't go into anything that will result in water ingestion.

Probably wouldn't have happened if he didn't hit that mud hole at 20mph....it wasn't even that deep otherwise.

It depends on what you do.

On dusty trails yes you should have one, Water crossings here in the U.S are not too common but they happen, off course you must observe common sense and if it is possible walk it first and check the depth.

Also as someone previously mentioned some trails do get some water ponds (very common in Texas OHV parks), those ponds sometimes have holes on them where the Jeep can take a small dive, water could get over the hood for a few seconds. having a snorkel well certainly give you a piece of mind during that Oh shi*** moment.

I have one on my JK and i did raise all breathers as well. This wont make it a submarine neither that its the intended use of the snorkel, as there a lot more that will be required make waterproof. After certain amount of time water will start to get into the cabin, via door seals and vents.

I do live in Houston where flooding is pretty common, and in many areas during a heavy down pour it can get bumper high, at the entrance of my subdivison it has gotten headlight high twice.

The key is insurance since hydro locking the engine is expensive. I think the issue is the intake is a vacuum and water pushes up under the hood with no place to go.

But snorkels aren't inexpensive and many require cutting permanent holes in the hood. They usually mount on the passenger side, although a WJ I am looking at (another thread on that) has an Australian snorkel on the driver's side.

I doubt submerging pentastar at 240f is a good idea, with a snorkel or without.
IMO Snorkel is for "one wire" diesels with a clutch steel cooling fan.

Best advice I've seen this entire thread.
Most folks are either too macho or too impatient to check before they cross which usually ends in disaster.

If I did not have the prefilter I would not have gotten a snorkel. That said I have the pre filter on the snorkel and it has worked for me.

I try not to go in water that deep where I have to use it but I have had it in where I needed it driving thru flooded areas to get medical in or people out .
