[s-cars] Cooling system help needed

[Stott Hare]

The part you mention goes from the thermostat housing on the block to the
return feed pipe from the after run pump and the heater core.  The hoses to
the after run pump should be visible from above looking down from the right
of the throttle body/isv.

There is another hose above the thermostat housing area is more prone to
failure.  I can't say I ever heard of the 034 121 063 C failing.  This one
runs from the banjo bolt under the water manifold to the coolant return feed
from the turbo (small metal pipe that runs behind the timing belt cover.
Several have replaced this in the past, and Scott Mockery even put a
replacement kit together for it.  This part is #27 on illustration 145-25,
160mm of 10x3.5 water hose (N 020 262 1).  Depending on condition, you might
also choose to replace the two worm clamps, 12-22mm size range.

Hope this helps,
-Stott

Oh great ones...

The audi gods are displeased as I have not paid my obligations  
recently. Nonetheless, I am a faithful pilgrim and will make proper  
obeisance this weekend in manual labor under the hood and the  
appropriate cursing and griminess.

I need some help trying to figure out which cooling hose has  
ruptured....it would seem simple, as I have the ETKA running under  
Parallels, but the diagrams are a bit vague for me...

The hose in question lives beneath the intake manifold and SEEMS to  
connect from a small pipe to something which I can neither see nor  
reach (possibly the aux. water pump?)

IF, I have the scenario right, do I need to order P/N: 034 121 063 C  
or can I safely substitute an appropriate length of standard high  
pressure/temp hose and clamp it in?

Thanks for any advice.

Best
