Outer Limits 4x4 Board

My old girl has always gotten a little warm climbing hills with the camper in tow, but it never uses any water or boils. So I decided to check out the clutch fan & found it to be a little weak.

To reco the fan is pretty easy, you just need a tube of the gel (oil, silicon). The only place I was able to find it was Toyota Spare Parts & it was only $11.69 GST inclusive.



With the GQ, after removing the fan from the engine, its just a matter of removing the fan from the clutch pack. Just four 10mm bolts.





Not sure that it was really all that important, but I made a witness mark on one lug of the clutch pack so it would be easier to put it back together. Then its just a matter of undoing the four 10mm bolts holding the two halves of the clutch pack together & prying them apart & removing the o'ring.







After that its just a matter of cleaning the old crappy gel out of the two halves...



Then squirting the new gel into the clutch, refitting the o'ring...



Bolting the clutch pack back together (a breeze with the witness mark)...



Finally, bolting the fan back on to the clutch pack.



Overall, a very easy thing to do, hopefully it will have some benefits to the old girl.

I'll be interested to see how this goes - I've used the Toyota stuff many moons ago with zero success, perhaps they have improved it...

It seemed to work well on the fan in my 304 Holden V8.

Can only hope it does just as well here.

I am waiting to see too mate, and hoping.

You can use more than one tube or fill it with bog for a fixed fan also

Yeah I usually use 2 tubes in toyota fan hubs.

I think you have bolted the fan on the wrong side of the clutch you may want to check that one mate. Looks good mate.

I think I will have to get another tube.

I did notice that before it was all refitted, luckily.

Would have been super unhappy with the end result if I had of fitted it in backwards, lol.

Turns out you need two tubes of the gel to do the job.

After I had it finished, I thought it felt a little weak still. Then after I started it up & grabbed the fan, it was just too easy to stop.

Quick drive back to Toyota & was told that the rule of thumb is usually one tube for a sedan & two tubes for a 4wd.

But it seems bloody good now, lets hope...

Do it in an area away from where you want to paint anything. That stuff never goes away if it gets transferred to steel surfaces.

Done exactly the same thing on my old gq used 2 tubes and made a big difference to the temps etc .

We just use glycerin from woolies. I think you'll find that's what the Toyota stuff is. Try mixing some with potassium permagnate (condies crystals) and see if it catches fire......
