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. > 4.

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! |
