What was in there to begin with, the orange stuff? HeyYou is right, you don't want to mix them. It's cheap insurance to drain it all, then add one type of coolant. I run the cheap Walmart SuperTech green concentrate mixed 50/50 with distilled water (never use tap water). The Mopar orange is actually better because it contains silicates which (hopefully) seal any minor head gasket/surface imperfections, but I've already sealed mine, permanently, I hope.
Jack up the rear end when draining. Jack up the front end when bleeding. Keep heater temp **** set to full hot when doing both.
Reaching thru this hole in bumper valance gives you access to the radiator petcock.
What are those holes really for?
Been trying to figure that one out.
I finally got fed up trying to figure out the petcock ... pulled the bulbs out of the fog lights, removed the 4 (bumper) bolts, pull off the whole bumper. Fairly quick and easy. The petcock is not threaded, an O-ring holds it in place basically. Use some pliers, twist, and pull at the same time, reverse to seal. The tab should butt up against the radiator and be clocked 12 to 6. NOTE: If you pull too much, it will pull all the way out.
