Ross,
My 1998 4.0 takes quite a long while to reach an indicated 102 C
and stays there, as if glued, with the occasional assistance of the
electric fan. The gauge is a modern VDO and the needle position is
roughly 40% of the scale, which seems to reflect "normal" to me.
Only on a 102 F day with a possible superslab temp. of 130 F did
the thing reach 108 C.
The question is... what makes you think the gauge is accurate?
I have a query out to Mark Reeves at MMC about the "correct" operating
temp. and what the gauge is really indicating and will let you know when
I have gotten an answer.
A Land Rover 1993 3.9 would operate at ~189 F, but it has an enormous
radiator built for cooling the vehicle well at idle under heavy load and high
temps. at high altitudes... which it does. Don't think for a minute that
the stuff posted here on the old cars is gospel for yours. Pick up some
anti-freeze for alloy engines from your local Land Rover dealer and mix
it 50/50 with distilled water, use some RedLine "Water Wetter" or BG
"Supercool" with it, change every two years, and you won't be draining
any "particles" out of your system.
Try driving the car a bit more too as I have that many miles since April !!!
