Proper Coolant Drain, Flush, and Fill Procedure?
What is the proper drain, flush, and fill procedure for my 4.0 Wrangler? I started by draining the coolant from the radiator and only about 1 and 1/2 gallons came out. When I got ready to fill it up I just stuck a garden hose in the radiator and before I knew it it was run ning out of the top and wasn't going down. I went ahead and filled the overflow bottle up to full. I don't think it even took a gallon in all by my estimate.
When I started it I just let it warm up idling because I had the drive shaft unhooked doing my pinion seal. It usually runs right under the 210 mark on the temp gage but it went past 210 by a little ways and then I shut it off. I watched it and the radiator started bubling just a little bit of fluid back into the overflow bottle.
Is there a bleeder valve somewhere or something that I should have opened? I think there is a bubble in there and the thermostat isn't opening because it doen't have hot coolant touching it.
