Morning All,
I'm just cross posting this from another list for Maarten at All American. He
is having problems with a clients 105 series and overheating and is looking
for suggestions:
Hi All,
then he added in response to other questions:
If you have any suggestions/questions, post them here and I'll cross post to
the other list.

An obvious cause is the fact that the car is armoured. I drove armoured LRs
in Bosnia during the war and the additional weight is extraordinary, despite
beefed up suspension and engines etc. Hauling the additional weight up icy
roads with 4 in the car meant the engine was working very hard indeed. And
so was I!
In 1st gear, low or high and with no ram air effect on the rad, things are
likely to get a little hot but the cooling system should be able to cope. I
would say that probably the cooling system isn't man enough for the job,
unless of course there is a more obvious problem with the system. Hard to
tell from the text below but little to go on so far...

Julian,
Toyota make these vehicles to do better than this. I think this
problem is something simple that is being overlooked, maybe because
the vehicle is new and certain things are assumed. The people driving
are probably not fools but it is easy to overlook the obvious. This
vehicle is new so was it good at first? Is the water circulating? Is
the thermostat opening? Is the fan coupling working? Take the
thermostat out, and leavce it out for a week or so. Check the radiator
temperature at top and bottom when the vehicle is hot. When the engine
is hot check that the fan coupling is locked. Drain the coolant and
flush the system.
Is there any evidence of steam when the vehicle overheats?
If all of the above are OK fit some greenhouse misters in front
of the radiator, with a reservoir bottle similar to a screenwash
bottle. Put a push switch in the car and give the rad a short burst of
water every minuet or so, or when the temp. gauge starts to climb.
This has a very good effect on the cooling capacity of the system.
Regards, Clive.

Another very simple thing to check if they have any additional
electronic fans fitted in front of the radiator - are these connected
the right way, i.e. are they blowing the air through the radiator from
the front, or are they trying to suck the air outwards from the engine
bay (thus working against the natural air flow through the radiator)?

Hi all,
Well. there's not much to add - Maarten has forgotten more about
Landcruisers than most of us will ever know. One thing that puzzles me
is why the engine gets too hot before the gearbox / transfer box
temperatrure goes beyond the limit. That may have to to with th fact
that that 1HZ is not as robust as 1HD-T.
