Broken Jeep Wrangler TJ
 

The girl friend took off on the weekend to get away from Melbourne
(Australia) for the Grand Final, and did a bit of off-roading at the back of
her family farm up near Echuca - the farm backs on to the Murray.

She drives a Jeep Wrangler TJ 2002.

During a creek crossing she rushed it too fast causing water to spray every
where and the engine stalled. On inspection there was water around the air
in-take and water in the air filter box. It was presumed the engine had
sucked in some water causing hydraulic lock (is that what you call it? My
words not hers :) ).

A three hour walk back to the farm house where they picked up the 4.2TD
Patrol to go and tow the Jeep back.

She rang me last night to tell me and I was hoping it was water on the
electronics that caused it to stall but it still hasn't been able to be
started.

I asked how deep the water was (i.e. was it above the wheels?) she wasn't to
sure - being hopeless with attention to detail. I'm assuming it wasn't above
the wheels.

So if the engine did take in a gulp or two of water what are some of the
likely outcomes? Is there other things that we should check that may be
cause of engine failure? (The Wrangler engine is a 4.0L petrol straight 6)

If the engine is stuffed can this sort of thing be covered by insurance as
it was an 'accident'?

Thanks for your help and suggestion's in advance.

Cheers,
Rhu

Far more common is to get water inside the distributor cap. Cold water
splashes on the outside of the cap and masses of condensation build up
inside. Same for the sensors on the throttle body

I would recommend someone open the cap and the plugs and sockets on the
throttle body and give it a spray with WD40 which displaces the water
out.

Now if it won't crank over with the starter, then I suspect water got
into the engine hydrolocking it.

A hydrolocked engine stops and the starter won't crank it over. A wet
engine stops, but the starter still turns it over.

Re: Broken Jeep Wrangler TJ
 

No dist cap in the '02 TJ, uses the coil-on-plug design, at least in North
America, not sure about Australia but no reason to think otherwise...

To the original poster... Was there water past the air filter? Water in the
lower half of the box may not have gotten past the filter.Was the inside of the
intake tube, between the filter and throttle body wet (your post just said
"intake")

If she can crank but not fire, you *probably* did not get hydro-lock. If she's
already tried to cranked it, and it wouldn't, you will probably need a new
engine, because when water is sucked into the cylinders, it bends conencting
rods, valves, and can punch holes through the engine block.

If the water was high enough, it could have gotten into the computer, which
would cause a number of problems.

Also be sure to change out your diff fluid and tranny and Tcase fluid, if the
water was that deep you probably have water in those as well.

Don't know about insurance for you, in the USA many insurance companies total
out flooded vehicles. Don't count on a new engine via the warranty, either....

Re: Broken Jeep Wrangler TJ
 

Thanks your help guys.

Unfortunately the end result it pretty bad. The engine suffered hydro lock,
bending values, breaking conrods, and punching bits and pieces (that's
the technical term) through the engine block.

The mechanic started looking at it yesterday arvo, we should have the full
prognosis tonight.

Thanks for your help again,
Cheers,
Rhu

P.S She isn't a blonde but bloody well should be.
