I posted a thread a couple of years ago on replacement of the bearing itself without spending the $600+ to replace the whole casting that it is pressed into. The double-row ball bearing can be obtained for about $50. No less a pain to fit though.

I decided to pull the belt of my ute tonight as it really played up today again in the heat, pushing about 7ton up a long grade, temp went up as usual and started to loose power.
It appears the idler below the aircon has a buggered bearing, its still tight but makes a hell of a rattle, so Ive ordered a new one. The viscous fan appears to be working ok, its certainly coming on, but how effective it is running is another question. But the biggest issue is totally my fault, the radiator was totally full of crap to the point that you couldn't see through a lot of it, Ive blown it clean and will be interested to see if thats the problem solved..Ill be giving it another work out tomorrow so hopefully thats the 2 issues answered for..

As a side note, my spare belt thats been under the seat of the last 2 Utes doesn't fit, I was told the 2.4 and 2.2 used the same belt..glad I found out in my driveway and not out in the scrub.

Ran the ute all day yesterday in extreme heat and was 400kg heavier and not an issue. It held its temp with no signs of heating up or the other symptoms, so I can recommend to pull the fan cowl off and get some compressed air or water into the radiator and give it a good clean out, only takes 10 min.

Thanks Tim, you just solved an 18 month long problem I've been trying to solve and was too stupid to think of.... My Tractor gets crap in the radiator and needs to be cleaned out but for some reason even though the Defender gets driven round the same paddocks it didn't occur to me that the radiator might be blocked. I was off considering whether the viscous fan was on the way out or whether the bigger intercooler had somehow fundamentally altered the tuning. Sometimes its the bleeding obvious stuff...... As you said, pop the shroud and spend 10 minutes with a hose.
