'92 940GL: 2 Newbie Questions

[Andrew McKenna]

RH Drive.

1) There is a large diameter corrugated silver hose from something
mysterious at the bottom rear of the engine to something equally
mysterious just behind and to the left of the radiator. What is it (the
hose, that is), and does it matter if it is broken (mine is)?
2) There is a sudden new fluid leak from the engine / transmission, oily
lightweight red to clear in colour, coming from somewhere behind the
block and possibly closer to the LH side (and possibly not, I don't have
a hoist), perhaps 25ml (1 fluid oz). Is there a 'most likely' candidate
or should I get someone with a hoist to take a look?

I looked on the Brickboard but I didn't find anything that matched what
I was looking for. Is there an engine diagram somewhere that would help
me to use the correct part descriptions?

1) This is the hot air hose. It takes heated air from around the
exhaust and ducts it to the air box, so the incoming air is no colder
than 5º C. This is only important when the outside temperature is well
below freezing - where you are in Oz this may not be necessary.

2) Red fluid is transmission fluid. This is used in the transmission
and power steering, although from your description, it sounds like a
transmission leak. There are a few seals that are relatively easy to
change, and a couple that require transmission removal. Also, assuming
auto trans, there are a couple of pipes that take fluid to the rad to be
cooled that can corrode through and start leaking, although these are on
the right side.

Thanks Mike, very clear reply. I'll fix the hot air hose before winter
(it does freeze here), and I'll get the car on a hoist with a clean
underside and try and spot the trannie leak.
