No More 6.0 Liter Degas Coolant Boilovers

Glad to hear all the supplemental mods appear to have helped. 
You’ll actually find out how much when you do a serious pull in real summer temperatures or sit in traffic for an hour when it’s 100 deg outside with the AC blasting and not just a cruise down flat I5 in late spring. 
The kicker is, all the recent improvements are to cooling circuits that shouldn’t need to be relied on to provide cooling, but only a method of transporting coolant for ancillary purposes. Like expansion tank and cab heat.
