AB's new GQ is finally here

[Winnie]

Pics look close but it’s 25mm

Fans themselves are miles away.

Yeah cool, so probably no chance with the bigger radiator hey? I've heard arguments for and against thicker radiators but never seen evidence to prove until people started putting these pajero fans on with the OEM radiators.

Average temp blasting on highway was 80. Only got to 95 on radiator hill so pretty happy Chappy!

Yep but also put VDO gauge on, pissed off the SAAS and taped into proper spot under thermostat.

The fans are miles away but yeah the hub is 25mm ish. How thicker is it?

I can properly measure if you like?

Nah all good cheers mate, when I upgrade I will swap out the radiator as well.

I asked the question of ADRAD when ordering mine, 84mm or 56mm , their cores are in 28mm modules and they categorically said 56. The thicker radiators are for trucks with great flow thru ventilation or static installations with no back pressure, as is not found under a bonnet. As I mentioned in a previous post, they actually flow test with water and air with their designs. So deeper isnt better in most cases.

Andy, you might recall I destroyed a fanblade doing the river crossing at Burgoynes? My fan blades would have been 30mm off the core I reckon and that was too close, and it actually scored the fins as 6 blades broke off. I ended up running a Toyota FJ60 fan blade which had a better offset, increasing clearance to 45mm. I didnt have problems from then on, but what was interesting is the fan blades actually flatten out and extend under load. I know this because the ears of the new fan blades or tips had a 15mm x 3mm chewed out piece and the only thing that could account for it were the tek screws I used to secure the shroud extension. Just a heads up if you start to look at a different plastic blade, watch out for the overall diameter

Thanks mate just measured the actual fan blades themselves and ironically they are 45mm as well.

Well I hope that is the magic number as well because the new kit coming my way has a Duramax fan, monster diameter, and a shortened hub shaft so the blades stay at 45mm as existing. My only 'fear' is that BD have swapped the water pump to some higher volume unit than the 45mm clearance was set up for, so I will have to chase this up.

Haven't driven it much but getting it ready to go camping at Easter so took it down the street for a clean and fill up.

Holly crap I didn't realize how loud these fans are actually, window down it sounded like a swarm of bees right near your ear!

Is the back of your bonnet still jacked up @AB mate from troublesome days?
