water crossings.

[laro]

An upcoming trip will involve some watercrossings. waterlevel might get up above the tires(31-10.5), or higher, but under the head lights line.
What to watch for on a RJ 70, 22R carburated engine?
Drive slow to avoid big wake.
Air intake hose at the highest point in the engine bay, distributer wrapping in plastic bag during the crossing, coil is waterproof ?
Spray all connectors and spark plug wires with silicon spray?
Loosen drive belt for fan, to avoid waterspray in the engine bay?
Do I have everything covered.

Any experiences would be helpfull.
Thanks, Ronald.

Don't get it stuck........


Have more than one truck,
Be weary of your starter after the fact...

Loosen drive belt for fan, to avoid waterspray in the engine bay?

...or if the fan has a viscous coupling hub, tie the fan off to something in the engine bay to stop it spinning.

Diff breathers up under the bonnet to the top of the firewall as the stock ones only just above the axless. They are useless.

extend all your breathers....
Snorkels are cheap insurance.

A tarp accross the grill can also be advantagous to stop any water getting in in the first place.

all the other bits and pieces that have been mentioned.

Try too let things cool off before any major crossings. If every thing is hot the moment the water hit it will cool rapidly and can suck water in through the seals esspecially if the breathers are too low or not working.

Select the right gear before you enter the water. Never change gears or depress the clutch while in the water. Dont stop keep it going.

WOW!!
all the suggestions that i have broken for the last 30 years...

your discription is good enough for me.
Snorkel is nice piece of mind.
plastic fans suck for running in water but your idea of slow and steady will work.
walk the route if no one has gone through before you (yep, getting your feet wet is part of the fun)
breathers: higher the better but in reality you will be checking/changing the diff fluids when you get back from the run anyway, right?
shifting while in water is fine just don't keep the pedal depressed for any length of time in the water since water can gat between the disc and the flywheel ... no traction = no action
i have taken gassers half way up the windshield in the past and there is no issues if you have your electrics water proofed.

one side note: if you go too slow and have the revs too low then the water pressure can cause too much back pressure and that will kill the engine. if that happens make sure you get towed or winched out ASAP since water can go backwards up the exhaust and into the internals of the engine. not good.

i would say make sure you have an 8274 mounted to the front, they work underwater (for quite a while) and will get you to shore.

as for cold water hitting hot objects, i have yet to see any damage of any kind from doing this activity. not saying it can't happen, just saying unless you are hitting 4000 rpms when entering i am doubting it.

oh, and if you do get stopped in the water for any length of time and get hydrolocked, pull the plugs and crank it over. also check your oil IMMEDIATELY for water contamination. if contaminated then DO NOT drive it till you change out the oil...

 

[laro]

Thanks to all for the info.
We will be with more trucks on this trip, they are all diesels. I will let them swim first.

bring new oil and a catch pan/bottle

I ended up getting my 74 stuck+hydro locked a few weeks ago; it was under for a few hrs and im still drying things out...
EVERYTHING took on water; was able to do the enigne oil in the field but had to wait a few hundred KM before I could get the gear oils done...
in retrospect I could have slightly pulled the drain plugs and gotten most of the water out of things right then and there, but hind site etc....

Be sure you know how to purge your water catcher; and pull the plugs etc
maybe turn your lights off before crossing; if you get stuck the lenses will fill and shatter...
have a pelican case for camera gear etc if you go deep;

Way over stressing here.... for this depth... just do it... really, almost all of these suggestions are ineffective and or unneeded. Below headlights... Yawn.,.. just drive. Really... no exaggeration... for that amount of water, we do not give it a thought.


Mark...

 

[crushers]

but Mark,
where is the fear mongering in that?

you jsut need to bring your sense of fun and wind your windows up!! I really really hate cold dirty water flying into the car as I hit the water too hard, stear too wildly as my wheels spin up the bottom mud because I over anticipated and got too excited at the first crossing for the day.. But gee it makes a great sight, its exciting and if there is an audience the flying spray is just great.

Crushers,

Most boat trailer bearings seize becasue people reverse hot bearings into cold water. If you ripped your bearings out 2 mins after you launched, they have plenty of water in them even if you just perfectly replaced the bearings and seals 5 mins before the ramp. If you look at most trailers with a seized wheel it is rust not lack of grease.

Voice of experience..... I travel long distances to launch and I have done it a few times....

 

[crushers]

bow waves work well, it creates a depression right in front of the rad.

if you do go too deep then get a tug out no big deal really... the lid on the air box was not attached properly before the run... duh.

Pin it and have fun!

When ever I think water crossing, I think these clowns.
