Alright, so i went in and changed the thermostat to a 180F, even though
the OEM replacement is 192, since i figure the cooling system can use all
the help it can get.

First off, good idea?

Second, when i drained the coolant, it was BBBB-LACK. It didn't foam up
much
when i poured into the jug i used to store it til i take it to
the recycler, but i thought it was odd that it was that dirty.

I ran a garden hose thru the system once it drained, so i think i got all
the loose crud outta the system, or do i have
bigger problems?

I can't see any oil beading up on the top of the fluid (or the bottom, I
can't remember what is heavier, though i assume that water with coolant in
it is)

thanks
