Yeah, good old Carl, thorough as usual.
While on the subject of letting the air in (wearing a silly grin while
stealing the thread)
I've had some fun moments with my A4 lately.
My background consists of a 1993 ford taurus and a bunch of jap bikes
and cars, nothing
german before this A4.

Sooo, I see what I thought was the "overflow" tank
is filled to the brim (engine hot). The thing has low and high marks,
maybe 3/4th of an inch apart.

This gets me worried, I unscrew the "overflow" tank cap to let
some "extra" coolant out -> it;'s freaking boiling!

I should have taken notice there is no usual metal pressure relief cap
i've got accustomed on the japs (taurus had one too i think, Yamaha in
SHO involvement maybe?
mine was pleibean nonSHO variety)

Well, I did take notice of the usual metal cap absence but did not
give it a second thought.

Anyhow, another day: I see the same thing with the tank "overfilled".
I unscrew -> more coolant oozes out.
Sooo, a few days back I get into the car start it and after a while
the low coolant warning on the dash
complete with the annoying chime comes in: now I;m LOW on coolant.

Notice to myself: do not touch thy "overflow" tank screw in cap on a
german
while the engine is hot: the coolant readings might not be correct
due to the overflow tank being PRESSURIZED! That and I gotta finish
reading
that user manual (another silly grin).

Anyhow, that was kind of amusing since no engine damage was done as
far as I can tell.

But but but you get an extra 1 hp when you install an aftermarket
thermostat.
It's like helping the car to warm up like faster or something :^)))))
Sorry, just can't resist.

Cold air intakes anyone?

WRX types used to roam this NG, but are probably in the wastelands
of web forums now

That or maybe i;'m confused by rec.autos.subaru that's been dead for
about 7-8 years now.

Once, as a teen, my dad told me to change the oil in his truck. I
started pouring in the new oil, I got about halfway through the second
quart can (remeber oil cans?) when, from the corner of my eye, I see
something moving near my feet. Yeah, a tsunami of oil. So, I quickly
put the drain plug back in, told my dad we're gonna need some more
oil. Oh and uh , Mom? Can you wash the oil out of this shirt?

sigh

At least I've never started a car without adding the new oil......yet


lol!
