I'm not sure I agree with this in the UK Maybe in UAE or someone wishing to rock crawl near Death Vally or towing a 3 ton caravan. But for someone like me?? I spend 99% of the time on the motorway doing 70+ odd trip over to Europe, so again long drive. Odd bit of Green lane, and odd bit of towing. I think the standard cooling system is more than up to the job, and since moving the gearbox rad I've noticed that the ATF stays Red and smells "sweet" for longer. I've also retro fitted a dipstick for the autobox, now most will say what's the point? but it's something I find easier, and so why not?? each to their own
I'd say if you want fogs and why would you not?? then crack on and carry out this conversion! I'd also say that I'm not the only one that's done this, but I have coved a lot of miles! so it's well tested
