Fitting viscous fan to 4BD1T

[inside]

I want to fit a viscous hub with fan and remove the existing thermo fan setup on my 110. I have all the part numbers to buy the items but is there enough clearance between the front of the engine and the radiator? Also does anyone know if the fan will fit inside the LR radiator shroud?

[THE 109]

No problems on mine. The viscous fan is slightly larger in diameter.

Thanks Eric

You might need to trim a little off the blades otherwise it will hit the bottom of the shroud. As Eric said, the fan diameter is larger. No problems with length as it doesn't have the spacer like the standard one has.

Did you find the viscous made the 4bd1 any quieter? It would be something I'd consider if it helped a little in the noise department.

No in short, my truck doesn't have any carpets or sound proofing so it's too loud to notice any change. It came like that being a truck motor.

Hi, any reason why you are removing the thermo fans? I was thinking of fitting some to mine, was going to measure up and see what common twin fan set up would fit from falcon /commodore etc, thought it might take a bit of load off the motor, maybe a tad quieter, and can set up to switch off for water crossings.
Cheers, Andrew.

Even though this thread is old, I would also like part numbers.

Viscous Hub
Isuzu Part No: NG-14055.010 Approx. $330.00 Australian

Fan
Isuzu Part No: NL NG-14050.019 Approx. $260.00 Australian

Adaptor Plate
Isuzu Part No: 897 1086430 from memory it was only about $40.00

I got my fan and viscous hub from a wrecker, it worked out considerably cheaper

You'll also need 4 x M8 x 20mm bolts these hold the hub to the adaptor

I recently had to trim about 15mm off my fan because it was just hitting the shroud. This was because we had moved the radiator back about 30mm to allow fitment of the intercooler

A standard setup has plenty of room

Might try a wreckers at those prices, I hear the Nissan Safari ones fit with small modification.

Have a look here if you want to find out about a fan and where to get a new one ,

Jock do you have pics of the shroud? Is it the stock one?
I have fitted the truck clutch fan to mine which is about 420mm in diameter and need to make a shroud.
Anyones thoughts on making a fibreglass or Kevlar one? Will need to be 2 piece to make it easier to get in and out.
Cheers

Just for info........ there is a recent thread on this site where the informed consensus says the back end of the shroud should be level with half the fan blade width. Apparently because that fan design sprays a lot of air off the ends of the fan blades, which should be outside the shroud.

That is, a beautiful thing.

Yeah not bad for $33 and an hour of my time so far.

Taking orders? Did you keep the v8 radiator or go Isuzu County?

[Vern]

V8 radiator with inlet and outlet modded to suit.
But if you are running the standard fixed fan you can use the v8 shroud upside down with some trimming to suit

Hi vern, how has the v8 radiator been ? Would you be up for making one of these shrouds again?
