Landcruiser Turbo Diesel

I have a 1985 turbo diesel Toyo and it runs considerably cooler than that. Don't know about an intercooler, but I'd be checking the condition of the radiator as a starter.

GP,
I have a HJ61 Turbo Diesel GX manual pulling a 21'6" 2450KG ATM van. Around town the temperature gauge is on 1/4, pulling the van at around 95Kph no wind flat roads/slightly undulating outside temperature around 25deg, temperature gauge still on 1/4.

Increase speed to 105Kph same conditions temp gauge goes to 1/2. ( No van, max speed limit still on 1/4)

Suggest you do not use biodiesel, more fuel, more revs, higher temperature. I would get the radiator cleaned out, and check the theromstat. If you have an automatic I would install another Transcooler in series with the original.

Suggest you watch your weight my HJ61 can pull 2500kg ATM. I do not know about the Sahara. Your 85, 60 series could well of had a Haymen Reece Towbar with 3400Kg stamped on it, with ball weight of 340Kgs, but things have changed in the Interim.

G'day Geepem

I think first thing i would do is get the radiator checked , temp gauge just below the red line dont sound to normal to me ...


Cheers......Dave

GP,
Further to the above, Mine is a 1988 year as well

Don't overlook the other obvious points - it could be your temperature sender or the guage itself.

A cheap way of fixing the problem is to get a can of black spray paint and spray the lens of the temp guage, this will make you feel much better and permenatly elliminate any further problems.

Hello,

I would look at the entire cooling system starting with the cheapest bits first. The temp sender can get sensitive with age also and I would consider fitting an aftermarket gauge to be sure. If it is auto I would recommend fitting and extreme valve body from wholesale automatics in Melbourne. I have no affiliation with the company but I bought a valve body from them and had it fitted. Shifts much better but still quite smooth and has a lock up on 3rd gear which cuts in at about 75km/h. Revs drop about 400rpm when it locks up and the thing takes off. Has transformed the vehicle and would be ideal for towing. I don't tow but just wanted the lock up on third. The catch is that it costs about a grand fitted but is the best money I have spent on it. Anyway good luck, temp problems are not uncommon on these but easily fixed.

Cheers,
Dave

GP, my 86 HJ61 never gets over 1/4 on the gauge, even when towing my CT.
I have heard of the temp gauges going a bit haywire occasionally though.
But I would get the radiator cleaned and checked, it's nearly 20 years old, and after it's done you will have peace of mind about it.

engine temperature is controlled by a thermostat. If it checks out ok then you can deduce that the guage is not reading the same as the one in the old car. If the temperature varyies during different work loads then you got a problem with the radiator. A good radiator with a new thermostat should cope easily.

Hi
I Also have a 1989 hj61 factory turbo cruiser and the temp
gauge always runs at 1/4 it had just went over the other month so i changed the coolant and all is back to normal.
