i was looking to upgrade my cooling system. i was on ssdieselsupply.com. they sell a kit it has a 130gph pump , t stat, and cooling fan. however the dual thermostat article on this site warns against using a 130gph pump on single tstat systems, saying it would cause excessive pressure w/o the dual crossover. so i guess ss supply's would be a bad move? what would be a good one?
