Thermo Fan for GQ

Hi searay,
thanks for replying mate, off the top of ur head...do u know what size they r?
I will be wiring it up to the original plug...im fussy like that :-)

Always believed that these car makers know the best way to do things or they wouldnt do it that way.
Cheers

There are heaps of fans on ebay at present....including a number of dual fan set-ups from Falcons etc.

Its cool searay,
no need thanks.

Thanks Pete,
I dont have the overheating problem Pete, I just wanted to replace original before she locks up. They are there for good reason, everything helps in extreme hot conditions when stuck in traffic because all you 4wd'ers are heading home from your dirty weekends :-) .
I will check out the falcon twin system and measure it up.

What size fan did you buy.....Are you sure it wasn't a "Davies Craig" brand?....they come in 10, 12, 14 & 16 inch sizes.

Thanks Bullwinkle,
Thought of doing same thing, but i decided to fit the biggest size i can.

S&N,
the fan is on its way out when you spin the blades and they either wont turn at all, or feel lumpy. Usually a good indication that its time to replace it before it locks up completely while you are off on a long trip.

The fan (behind the grill, mounted on the air conditioner condenser) Is supposed to switch on when engine temp gets to a certain degree. It is wired up to the air conditioner. So it wont run unless you have your air con switched on.

In answer to your question.. "should it run when hot", its designed to run when engine reaches higher than normal running temperatures, usually this happens under load (climbing hills while accelerating or towing) BUT it is wired up with a safety cut out switch which will shut your air conditioner down if the engine gets way too hot. Reason why this happens is to remove the extra load that the air con system puts on your engine. Thus helping your engine try to cool down faster.

Chances are, you probably checked yours while engine was too hot and the system shut down your air con from running alltogether, including the fan.
Hope that helps mate..cheers

Ange,
Not sure about the GQ, but the 4.2TD GU is different to what you just described.
On mine there are 2 switches located in the bottom radiator tank. The one on the passengers side (which I have unplugged), causes the air conditioner to switch off when the coolant temp reaches a certain level....this means the air con pump AND the fan in front of the condensor.
However, if the coolant continues to rise in temp, then the 2nd switch (on the driver's side of the bottom radiator tank), is triggered and turns the fan on again (but NOT the air conditioner)....this is to try to aid the radiator to cool the system down again.
As stated, I have unplugged the passengers side plug so the air cond does not cut-out.....but I do have the extra VDO gauge fitted, so I can keep an eye on the temp of the coolant as well as several other areas of the motor.
I have also fitted another electric fan (only 10" at this stage, but I'm looking at fitting a larger one) to the opposite side of the air cond condenser (ie: the driver's side). Thsi is controlled by a switch that i can turn on/off at will. I turn this on whenever the ambient temp is over about 30oC if I'm going out of town.
