What kind of coolant are you guys using?
The coolant in my truck is mostly original. It should probably be flushed, but I plan on doing that whenever I get around to repairing the leaky heater core.

Because of the leaky heater core, the truck lost coolant on the passenger-side floor, so I had to add about two gallons of the red diesel stuff I got from Tractor Supply to get it back up to a good level. Add coolant to the surge tank until you can see it centered in the sight glass.
