Oddly, the last time I started the truck and ran it to try and do a flush, it overheated in a matter of minutes just idling.
Today it never got over 180 idling for 45 minutes and I was able to drive it a couple miles with no overheating.
I did, however, observe bubbles in the top of the radiator tank. Air bubbles from sitting for a month with no water in it? Doesn't seem like it.
My phone won't download pics to my computer for some reason I can't post any right now.
