I heard last weekend of several people having problems with the turbos "exploding" during
water crossings. Apparently the turbo is either under or at least low down on the side of the motor so that when attempting a
water crossing after a period of normal speed travel the turbo is hot and cracks when it hits cold
water. Can anyone confirm this???

Graham,
although I am not a fan of the engines because of the difficultly servicing basic components and the placement of a/c compressors and alternators.
I do believe if you are going to drive into deep
water with a turbo that has been working you may cause some damage.
I don't take deep
water lightly having had a very bad experience once and I learned my lesson for life. I am sure the sit and have a cuppa approach while you check the depths/bottom and flow will allow all the hot bits to cool and you will have no problem with the turbo.
None of the utes at work have had any turbo problems and many have some big hours on the engines.
Have a good one and be cool,
RA.

As above,
Good advice, and not just the turbo, diffs, gearbox and transfer will all be much happier!
Cheers.

Hi Rockape
Thanks for the reply and advice. From the other replies it seems that all one has to do is let the turbo cool of before "charging" into
water which is good practice anyway. By the way I looked at your profile and notice that you have a 6.5L V8 motor in a 1989 troopy so my guess is you are a mechanic?? but anyway can you give me a rough ides how much the conversion cost you?
Thanks
Graham

Graham,
I am not a mechanic. I am an underground bonehead but I do have a lot of experience with trucks and earth moving machinery. One old boss I worked for had a policy of "if you broke it and it was your fault. You will work on it until it is fixed for nothing." That taught me to respect machinery very quickly.
Have owned and driven 4wds since my early twenty's and drive them every day underground and on the surface.
When Linquip fitted the 6.5 to my old girl it cost $15000 and that included a new a/c compressor and installation. That figure was 8 years ago though.
All the best,
RA.

Yeah I heard the factory AM/FM radio's change stations when nobody is around.... spooky Hey!
Maybe more urban myth then fact.
No mention of it on Lcool
forum so I would say it was started by someone who is a part time engineer in their sleep who thought having a turbo down low is a no no..... fancy putting a turbo there, what ever were they thinking.
Toyota's seem to get more then their fair share of mystery faults that everyone hears about but nobody see's..... could be "tall poppy syndrome"

We have a fleet of criusers and hyluxes and we have had no trouble with the turbo's at all....even as low as they are and hot and sweaty getting speayed or emersed in cold
water and all......but we have had
water get into the sensor plugs and that has caused us some grief....goes for our prado's too.

Graham
Consider this.
After doing many
water crossings on the Old Telegraph Track to
Cape York, this year.
Every crossing was walked before we did them. That means that turbo temps had idled down to a minimum, before we immersed the vehicles. Some deep crossings, and some shallow ones.
Doing the
Gibb River Road, we did basically the same thing,
ie....look....observe......walk if possible...
End result no damage to anything.
I think someone is "yanking ya chain" there.
Cheers

I crossed the Simpson in the heavy rains July/August last year.
Lots of
water and mud.I was driving my 2008 2OO series TT diesel LC.
It never made home.
Main problems were--One Turbo blown, alternator knackered, power steering rack needed replacing,new wiring harness, new brake pads and discs.Also a new battery.
Turbo ,rack, and wiring harness were covered by warranty .I had to pay for the rest.
Recovery from Mungeranie to the nearest Toyota dealer was covered by warranty.
