i was wondering if anyone here has done any yota cooling upgrades, or had any ideas on the subject. i know there's a $200 bolt on electric fan, and that'd be a nice easy afternoon, but i wonder if it's worth the price. seems like about a hundred bucks worth of brackets, after looking at fans in the summit catalog. anyone put in a bigger(thicker), aluminum radiator, for hopefully more cooling ability? and how about fittings and hoses...any issues there? or should i just leave my relaible as hell engine alone? all help is appreciated.....
