The wife was driving the Blazer today and
noticed that, at one point, it started to
overheat. It then started to cool off, possibly
because she was then at highway speeds.
At home, I checked the oil level and it looked
good. I checked the coolant reservoir and found it
to be very dry, with a mud like substance at the
bottom. I put some water/antifreeze in and it's
still very muddy.
Any ideas what this is?
A few days ago I heard a fluttering-like noise
coming from the area underneath the glove box. It
started and ended very quickly.
Thanks in adavance for your help!
