u sure the fans are on high-speed when it gets hot, not just low speed? are both working?

on the highway yes, but once he re-starts it they should be going fast if the ecu senses high coolant temp.
when you switch a car off it actually gets a bit hotter before it cools down, but not to the extent you're describing.

Even though the radiator is new ... I thik i might upgrade to a better radiator ... might just have to bite the bullet and do it.
Knowing my luck there'll still be an issue. Weird thing is that it is only overheating on the rear cylinder near the cylinder head temp sensor. Might replace this first and test again. It'll be a case of trial and error till i get it sorted.

I am still stumped. stumped .. man ... what a ute ... u say that you have a big oil cooler .. maybe remove it or mount is somewhere else or get a smaller 1... if its in front of the radiator .. restricting air flow will cause that .. but only on inclines as the motor is working harder but the air is being restricted ... but it sounds like it could be anything with what you have done to the car

I am thinking of moving the trans cooler to the middle up the top behind the grille ... at the moment it is near the bottom driver's side (and AFAIK that's the coolant return back to the engine after it has been through the radiator ... I suspect the trans cooler might be heating it up too much under load).
It will be my next plan of attack ... as the current setup is mounted up against the A/C Condensor (and it really starts heating up the coolant when the A/c IS ON). If I move it to the centre near the top ... I will mount it further forward and leave a gap between it and the condensor and see how that runs. I am running the PWR V8 trans cooler as well ... can't remember the dimensions ... but it is a decent size.

I am still stumped. gees mate ... what about the trans cooler ... if that is restricting the air flow that can cause overheating cause the motor is working harder but not get enought air to keep it cool .. something to keep in the back of ya mind mate

have u checked things like the coilpack and ran a self test on the ecu. if the spark is not doing what it should be doing it can on rare occurances cause the car to overheat

Just replaced the coilpack as I was getting backfiring issues (EGAS) ... so has a new coilpack in it. Also had new leads and plugs in it.
Also had a scantool plugged in and did the complete start-up to warm test ... and on road testing as well ... no codes came up at all.

hey Mechan1k! I've been having minor issues aswell,pulled the whole cooling system down,had the radiator flushed,pulled the water pump off was good put back on,flushed the block out,checked the temp sensor.still have no idea what it could be?also checked the thremos! to me it fills like a air flow problem as it heats up a little in traffic at stand still.I've also upgraded my trans cooler and think it might be the location of it! bottom driver's side of condensor.

See ... that's where my transcooler is (I fitted it in winter hence I didn't notice overheating issues till Summer).
Now the return coolant back to the engine (where it is meant to be cold/cool) is down where I have the transcooler. There is a replacement cooler the taxis use ... it's a long thin one that goes the entire width of the condensor near the top (and some near the bottom). I will try and relocate the cooler first ... and I am going to bypass the radiator as well and just run transcooler for the auto only ... taking some heat out of the radiator as well.

I've still got my original cooler,might try and put it back on and see what it does! if it works I will know it's the new cooler's location.
