1985 HJ60 Turbo Landcruiser with continuous overheating problems.
It has a Schwitzer Turbo fitted from new and I have owned it since 110,000Klm.
I have tried everything - viscous fan, block off bypass, remove thermostat, fitted pipe to top of radiator tank, new radiator, full motor overhaul, rebore, new head, shifted throttle body from down side of motor to top of inlet manifold, injectors and pump serviced.

Vehicle runs hot over 100klms per hour though if you drop back to 100 the vehicle return to normal. Drive in fourth gear and the temperature stays normal. In colder climates no problems. Any ideas.

is that a factory turbo? if not then perhaps it was not the correct turbo that should have been installed in the first place? Grandfather also has a 60, he put a safari (i think) turbo onto it about a year ago and has no probs with it. and under bonnet temps have not changed at all.

Have you considered a Davies Craig Electric Water Pump?
I don't actually have one (yet) but my research indicates they are pretty good. That still doesn't get away from your intial problem though but I can't help you there sorry.

I have a 1983 Turbo Diesel Cruiser,it is fitted with a after market AIT water cooled turbo, which I believe is a Garret TO3. I have the same problem if I push it over 100 k,but the temp gauge will only rise to 3/4 in the white area whereapon the viscous fan will cut in and drag it back down to 1/4,but it goes back up and repeats the process.On steep drawn out hills it will climb nearly into the red. I have never boiled even on the hottest day with the air on,nor lost any significant amount of water,but it is a worry as to the long time longlivity of the engine.I might add that I have a oil cooler fitted. I believe it is a common problem with the 2H motor. More HP more heat. Hope this helps. ( I live in QLD).

it's $$$$$$$$$$ but probly putting an intercooler on would help in cooling the charge temp, plus some added pony's
