radiator fan issue
hi,
was doing my radiator bleeding today and noticed, when my car is running the fan wont kick in till its about 3/4 of the way to Hot on the temp gauge in the car.... im not sure weather gauge is fault or thats normal or if my thermostat is boned... but in traffic it tends to be hot (i personally thought due to no fresh air) on freeway perfect never over half way, but stationary today i just noticed waiting and waiting for fan to kick in and it did when 3/4 of the way to hot...
any info would be appreciated.
Thanks

My VS is the same. My VP kicks in at halfway.
Doesn't help you, but you're not alone.

This is completely normal - when the car is stationary there is no cooling airflow thru the radiator and the engine will increase its temp till it reaches about 3/4 gauge then fan will kick in and the gauge will drop to about 1/3 and fan will turn off.
When the car is moving you have a continual flow of cooling air thru the radiator.
The Ecotoc is designed to run relatively hot, which is why they run a 1.35Kpa radiator cap which is pretty high. The higher operating temperature improves economy and decreases pollutants.
IF the engine does overheat, it will reach the top of the gauge and just before it does this the warning chime will sound. I've only heard this once when my waterpump seized - gauge went rapidly from half to full then warning chime sounded....switched off immediately and avoided any damage.

yes hako is right i had the same on my last vs always kicked in at 3/4 and dropped to 1/4 ( lot lower on my v8>the v8 never goes of 1/4 even on a 40plus day with the aircon on it just dont budge thanks god )

on my vs the fan wont switch on till two notches from the top, and switches off just below the second last notch, thats way to high for me, and I've changed sensors and all that stuff.... Is the computer adjustable? can ya make it turn the fan on at a lower temp ?
Instead of mucking around the guages etc, its best to see what temprature the car is running at. If its within the factory range, then there is no need to go mucking around with sensors etc.
What tezza said - need to check the actual values rather than what the numberless guage says. While probably not likely, your guage could have shifted calibration or at least be different to others.
I have changed the sender unit, to see if it was faulty, no different, I tried a different gauge- shows the same, tested the fan relays according to the w/s manual, all good, it just seems to turn the fan on way to close to red hot. I suppose the next thing to do is somehow install another temp gauge (I've got a VDO gauge in the shed), and see if the fan comes on at 103c .

Ive read on here before of a guy who fitted a new temp gauge sender to his VS,and it made his temp gauge read up to 3/4 instead of half way,he took it back to holden and they gave him a different sender unit.Apparently there was a revised temp gauge sender unit relesed to fix the VS temp gauge from reading high.My VSV6 only gets to half way on the gauge, and the cooling fan cuts in and drops it to below a quarter.On the highway it sits at the second mark on the gauge.Even lower on cool nights.But around town it only gets to half way at the most.I wouldnt like my temp gauge sitting at 3/4 or more.It doesnt leave much room for error.The cooling fan on/off temps can be adjusted in the memcal.Ive had a bit of a play around with them before ,but Ive now got it set back to the standard settings,which works fine if theres no other cooling system faults etc.
ok, thanks for that, I'll try Holden, to see if a genuine sender unit brings the gauge down to a reasonable level
Id definitely try a genuine sender,Id also ask the spare parts blokes at holden and see what they have to say about it..Im sure I remember this guy also saying that the different sender he got when he went back to holden, was shorter than the one that made it read high.Anyway,let us know how you go with it.Cheers.

I got a genuine sender from a holden dealer in town, the guy knew nothing about a special sender for the Vs.. cost me $13 plus gst = $14.30.. made no difference at all.....
So I have worked out a way to override the fan control from the computer, now i can turn the fan on when I want it !!! not when the bloody computer thinks its time... I have taken the VS to Newcastle to pick up a caravan, went fine on the way up, I turned the fan on as needed. With the 'van on on the way back, I kept the fan on all the way, was ok except for the hills on Newcastle express way, and near Mittagong. Needs new radiator I think , got a quote from a cooling place here in town - $150... will do that soon. I have to go all the way to Queensland in a couple of weeks to pick up another caravan, it will have to be right by then
If that $150 includes labour then it is ####ing cheap as man. I picked my radiator up for $80 brand new from justcarparts on ebay.
Anyway my car does the same shit, so I installed a button that runs straight into the radiator lug the gives it power, through the firewall and into a button switch that lights up red when the fan is running. I tried to do it from the wire that comes out of the ecu but had no luck. It works great, you just push it when you pull up at lights, go into a carpark, when going through drive thru and she never goes above 1/4 (which is what mine sits at when cruising. Got the switch from jaycar for $8.
$150 across the counter, not incluiding labour. i've seen radiators on e-bay for cheaper, But i dont know If I'd go for somthing that may be made in china for the lowest possable amount... but I'm not saying that their all like that. This one will have warranty and a local suppier that I can go back to with any prob's ( mind you it might still be made in china...). I used the wire from the computer and the A/C going to the high speed fan relay, its a earth wire, so i cut it , and put it thru' a two way switch, one way things are normal, the other way, its earthed (the relay), and the fan runs when ever the ignition is on. I will have to work out a way to put a warning light on it...
