Wow guys thanks for all the replies. I had researched and came across most of the ideas suggested. This morning when it was cold, I was able to turn the fan a lot more than 5 revolutions, so I am assuming its buggered. Can I ask A few questions?
My car is a 96 petrol, is there any special fan clutch replacement I should be looking at or can someone recommend one they have used? From what I can see they look to be around the $100 mark on ebay, does that sound correct? Is there a heavy duty one you can get?
The other question would be does anyone have a link to the whole process? like a write up or do it yourself tutorial? Is it a tough job? I had a look on go jeeps site which is a treasure trove of info, but found nothing on this
The car is old and so is the whole cooling system. When I first got it, It only overheated on hot days when with extensive soft sand work. On the road, it has never gone any where near halfway. Since then I learnt to drop the tyres more and use low range more. that helped heaps but still on some occasions I had to crank the blasted heater. Replaced the thermostat, and wired the factory thermo to a manual override switch. Also removed the aircon condenser because it had no air con anyway, so that provided more airflow. Lastly I added 2 10 inch thermos in the air con condensers place. With all that, I have never had a problem since. Then last weekend, I noticed it was quite hot on a drive back from a camp trip, so much so I was running 1 thermo, and at times the heater just to keep it away from 3 quarters. The radiator is looking quite old and worse for wear, but before the fan clutch, seemed to be doing its job. I am pondering replacing it if and when I do the fan clutch, as I am guessing its going to be a lot easier to do it with the radiator removed.
Thanks heaps for all the info, top forum.
