we have used our 2009 v8 landcruiser UG for the last 2 years, we have had almost all of the issues spoken about in other threads plus some others due to the conditions it works in but overall best vehicle i have ever used in mining to date.
The one problem though we have just had is splitting the fuel cooler, when we pulled it out it was full of bleep and probably not working fully so we did not bother putting a new one in at $800+
has anyone else had this issue and does it realy need this cooler? seems to be working fine.

yes we have had problems with many of them, they didn't split they were eaten out by water trapped in the valley, this caused some engines to seize as the coolant loss wasn't picked up due to no radiator cap. They also have foam in the valley that soaks up water and holds it there. Many radiator, a/c condenser, a/c compressors, alternators and starter motor have failed

and I will say they are not the best u/g vehicle as I still drive an old u/g 1 hz cruiser that is nearly 6 years old and it has the same diffs, gearbox and engine it came with plus it hasn't rusted away.

They also rust quicker and the doors split where the window pillars meet the main door skin and the guards rust out. These vehicles are washed every shift.

No computer problems at all.

Gearboxes and diffs are great, no problems at all except the boxes alloy eat out the same as the old ones due to the harsh water. New box not bad at $3000.

Many of our V8's are in the tip in fact nearly all the 2008 ones.

Have a good one,

G/Day , RockApe, In your opinion what would be the most concerning thing for the average V8 Landcruiser ute owner??.

they are still the pick of the crop for mining.

Average problems for V8 owners are from my point of view only with no axe to grind.

If you keep the cruisers they will have the same problems as the mine vehicles over time.

I have a 22 year old 75 series with the original a/c evaporator and condenser. The new condensers don't cut it like the old ones.

If used in wet conditions, mud and water crossings, a/c compressors and alternators will fail.

Get a low water alarm as with new vehicles you can't check the bloody radiator. Radiators are not lasting like the older ones.

Starter motors are a nightmare to access and replace.

As I said doors will crack over time if used constantly with corrigations.

If you drive them as a Sunday driver they will last many, many years but that is not what they are made for.

Some will say that mining vehicles are not a bench mark, but I say it is where the respect is earned and that vehicle will go on to run for many fault free K's.

Do it easy and if you can't make someone pay

The cooler i was speaking of is the fuel cooler on the bottom of the transfer case.

I have also had the oppertunity to drive almost every vehicle ug and in terms of performance ive never driven a toyota with so much pull.

thankyou for your reply though.

The fuel cooler cools return fuel to the fuel tank.

When the pressure of anything is increased it generates heat due to increased speed of the molecule's moving and crashing into each other.

This is more evident in CRD engines due to there 20 thousand + injector and rail pressure.

The fuel cooler is there to stop the fuel in the tank from getting to hot and expanding or evaporating.

In cooler conditions it may not be noticeable but in hotter climates it will be.

This may also be an emission device.

So yes you do need it.
