I’ve tried all kinds of things to get it down: currently has an aluminum radiator, custom shroud, gap on the water pump, pulled some blades from the pump. I’ve seen all kinds of other suggestions on the forum but haven’t tried any yet. If you have some simple-to-try suggestions to start with please tell me! One I saw that looked interesting was reducing the flow, which was almost counterintuitive to me. Please keep in mind that 110-112 degree days isn’t unusual in west Texas, so I’d be ecstatic to get the temp down!
