The only time the oil light and warning come on is if your oil level is low.
A good flush and replacement with distilled water/phosphate free coolant/water
wetter will bring temps down a little bit.
The second hose for draining coolant is from the main coolant manifold to the
water pump and it takes care of the resevoir, heater core, etc. BTW you WILL
have fun doing this.

Subject: Cooling Q's
Well earlier this month I did a somewhat decent degreasing of my engine,
and I had a couple electrical problems afterward which cleared themselves up
after a day or 2.
One of them was my coolant temperature guage -- it would read full
(grounded). It finally fixed itself (I *THINK*), and under normal driving the
needle is directly on the right edge of the LED.
However, in even semi-stop and go (and most urban driving in San Francisco)
the guage reads about 3/4. My fan does come on, and it never overheats,
although today on the way home the oil light flashed for a second with an
audible alarm which went away as quick as it came.
My oil temp in normal driving is about 208 according to the MFA, and never
ever goes past 232 (and when it hits that it's only for a minute). From the
archives, I can tell that this is probably good/normal. However, why is my
coolant guage reading so high?
Is it or the sending unit malfunctioning? If so, why does it read close to
the LED like normal in regular highway driving?
When it *is* running at 3/4 or so, I tend to think that the guage is not
functioning because my car exhibits some distinctive symptoms when its really
hot -- slow to drop to idle, high idle, etc-- and these symptoms manifest
themselves when the reading is like this.
Any thoughts? Once I figure out how to do a proper coolant flush on this
thing I plan to do that.
Also, the bentley shows 2 hoses to be removed to drain coolant. The main
one is obviously the lower radiator hose, but what is the smaller one? Will
that drain the block?
Thanks for any ideas.
