i wanna do a ps cooler cause mine seems to have an issue with gettin pretty warm. im pretty sure it has somethin to do with the 110+ degree days, low speed drivin, and 35 inch tires. the pump seems kinda weak, so i was plannin on flushin the system, replacin all the lines and the pump, addin the cooler, and runnin strait lucas. beins it already has a cooler of sorts (i know exactly the line youre talkin bout), itll be that much easier to plumb in a bigger one, and mount it in front of the radiator.
