I had noticed the fan seemed noisier than normal lately.
I checked it and it appears to have seized up solid.
Can the hub be drained and refilled or does it have to be replaced?
Its a TD42 engine.

Cheers,

believes its a sealed unit, needs replacing, try ebay

 

[BeNos]

It's not a sealed unit but if the bearing has seized she is a throw away item
There is a beaut diy on here somewhere about recoing them rhough

 

[green troll]

Yeah most desel are serviceable.remove fan from it,if there still more bolts there, take them out and take apart. Clean out and add two tubes off fluid from Toyota.diy on it here somewhere.search.
As benos said if bearing it's a throwaway.

If it's seized throw it out and fit new one off ebay, wouldn't even be bothered pulling it apart but still drivable till the new one arrives

I replaced my entire viscous hub setup with dual switchable fans out of an el falcon - fit perfectly and stays much cooler as a bonus only cost about $250 all up as well

where did you out the thermo switch, thinking of doing this so I have cooling after the engine is turned off, mine gets really hot after shutdown.

Super cheap sell a thermo switch for around 60 bucks (without relay) fully adjustable, I mounted it near the pre filter on the lhs of the engine bay as the probe wire was too short to cabin mount it, I have hooked it up by a 3 way switch so that I can have the fans on a bypass, off or on (off so that I can do deep water crossings), I also wired each fan has it's own relay and fuse. I have it set at around 190 degrees F and it cuts out after a minute or so with a temp of around 180. They don't however fit with the existing engine fan still in place so they are a replacement not an addition

Put it on the other side of the radiator if there is room there.

 

[Mavtroll]

Nope no room there either... Good replacement tho anyway

Would be keen to see some pics of that mate...can you put some up??

 

[Mavtroll]

I can but you will have to wait - my truck is on a bigger truck in ISA and I'm in Canada - will post a few when I see my baby next

 

[steeples]

i have put these fans in and have just worked out instead of thermo switch you can use temp switch from laser etc. Rad has plug on the side, this can do away with capillary tube in hose.
