Thread: D2 conquers the Cape

Makes some sense. The viscous fan is designed to push the air flow forward thru the radiator, I'm just not sure. Not about to find out the hard way, either.

Having removed and refitted rads from a D2 there is no way it can move and hit the fan. I have done deep water crossings before even pre safari snorkel. Also I think I get away with a bit because it runs so cool even in the 33 degrees of the OTT run...

I had water over the bonnet of mine about a year after I bought it. I very stupidly took it through flood waters near Monbulk, Vic. The box trailer I had on was sideways in my mirror. Slow approach, kept the revs up a bit to keep the exhaust clear and maintain momentum. Only mod at that time was the snorkel and the chip. Car couldn't have cared less.

Great thread, nice to know D2s have still got it.

My TD5 D2 keeps surprising me how capable it is. I'm not the best 4Wdriver around, the vehicle has gotten me out of trouble that I've gotten it into, more than the other way around. Mind you, I take it easy these days. I have to say, an Ashcroft ATB LSD in the front makes a difference. One for the back, and I'll be happy. Lotto win.........

It's not hard(just dangerous) to stop a viscous fan not at operating temp using various precautions.

The only real concern I'd be having would be any sudden rotational deceleration effect on the fan when it hits the water if engine revs are too high. Could shatter fan blades if they're fatigued in any way.

That makes sense too. Now I'm not sure what to think. Oh well, situation normal.

I can't recall atm how much the clutch still drives in 'freewheel'.
I think it's 30%, but I'm pulling that number out of a certain orifice.

Remember the newspaper test to see if it's ok?
If you jam one in at idle and the fan stops the viscous clutch is knackered.

I'm hearing you. I really wish the Maxi locker I have in the rear of the D1 would fit the D2. Never mind.

Main issue with water crossings I found was remembering to turn off the air-con so the plastic fans in front of the radiator stopped spinning and didn't snap off their plastic blades.

Oh yeah i own a D2 and know what a standard one can do
Mine has a few mods and it just does it so much better
