Default AU ute overheating at 110 kmh

Hi all.
I have a au ute series 1 6 cyl that starts overheating when I get up around 110kmh. Went into the red the other day so I turned aircon off backed off to 100 and temp went back to qtr. Did this on most slight rises on my trip. I recently had a new radiator installed, block flushed and new coolant added but is still heating up. Had thermo fans checked and they are working ok. Runs cool in traffic. Any ideas . Cheers

Have you check all the Fan Relays under the bonnet?

It won't have anything to do with the fans, as they're only required when the cars going below 30kph.

Considering you've had a new radiator and flushing done, I'd be looking at the water pump, and maybe even dragging brakes, though you'd probably smell the brakes so unlikely.

as Sox said the fans are only needed at lower speeds, at higher speeds the speed you are doing supplies enough cooling air. sounds like a radiator to me, as speed increases so does the heat generated by the engine and it's reaching the point where the radiator in not keeping up

I had a similar problem years ago only mine was even more difficult to sort due to the fact that I had everything replaced before the issue arose. New radiator, water pump, thermostat and all hoses, mine still overheated when the engine was put under any sort of load, it was eventually diagnosed to be a faulty thermostat, even new stuff has it faults :(

head gasget ok? gauge not giving a false reading? new thermostat faulty? the thermostat is an easy one to check, pull the bastard out and go for a run or , or throw it in boiling water on the stove see if it opens.

Time to check the water pump - first check that the belt is tensioned correctly. Watch for for any water leaks at the pump and for any squeaks, rattles or grinding noise etc. If in doubt just replace it.

The thermofans will run if the aircon is on regardless of road speed,if they arent kicking in when the air con is running there wont be enough air being drawn over the condensor and the motor will get hot,is the air con condensor blocked/fins bent and stopping airflow?
Just seems weird you turned the aircon of and the temp dropped,i would have said radiator but if thats new i would look at the fans/aircon.

Wht did you have the Cooling system replaced, what went wrong to warrant the repair. If it overheated previously Id suggest a head gasket or cracked engine part that has issues under load.
It could be running lean as a result of a failed sensor, O2 or coolant temp. Or the temp sender is faulty telling you its hot when it isn't actually overheating.

Replaced the radiator etc because it was doing this but not as bad as now. Oil is still good colour so I doubt head. Runs smooth enough.has developed a bit of a grinding noise, thought it might be a pulley. Going in for a service tommorrow so I will get them to check water pump.

Yes, but in QLD you can be confident with a 10% leeway, so run in the 110 zones at 119, too easy!

Mechanic looked at ute today and found one of the fans seized. Water pump seems ok so will fix fan and take it for a spin to see what happens.

hey there ...if your still overheating..and all the physical stuff like pumps,thermostats and other stuff checks out..then try this (my young fella had this problem on his au 3)check temp sending sensor back of motor...if not that then check the dash gauge..(that is the problem on the au 3)..the temp gauge goes off the dail every now and then so i put a capillary gauge (piggy backed on top of thermostate housing ..I had a spare one modified ) in the car temporalily ....reads the real temp and when it over heats on the dash gauge the capillary gauge reads true....but if you can get ur hands on a laser temp gun when ur gauge reads hot stop and take a reading if temps are good then its ur dash gauge....if that has to be fixed its about $250 to $300 ...the dash cluster has to be re programmed and when it is re installed the coil pack has to be replaced at the same time..as the coil spikes the dash cluster and corrupts the program....hope this helps

How good is this forum?

My young blokes AU ute was doing the same thing. Going up a hill or giving it a bit of a rev through the gears (manual) and the temp would run up to two thirds. Back off and slow down and it would come straight back to the "o" of "normal" where it usually sits.

I gave it a full flush today, checked thermostat and radiator, all good. Had a google search of AU overheating and came up with this thread. After reading it I went back out and checked the thermo fans. Only one working. Swapped a few relays around and now both working and temp staying on "0" under any conditions. Job done!
