Thanks a lot for the input.
My wife has - almost voluntary - donated a couple of her small mirrors that
I hope will fit under the waterpump. I will then do the test Rotax
describes: Run for 5 minutes and check if droplets can be seen from the
drainopening within the first minute after shutdown.
Before that I will check and double check all coolant hoses before ordering
any spareparts.
I will keep you posted on my findings
Dave good to hear the lenses have worked out well ;-)

The air through the engine compartment can create the appearance of a hose
leak where there is none and the actual source of the leak is elsewhere.-
You can also use an air compressor to apply low-pressure (10-15 lbs) to
the coolant system-via removed radiator cap.- I use an adapter I made f
rom automotive tubeless tire valve stem with a shock rubber bushing (donut)
-slipped over the valve stem.- By grasping the rubber donut one can for
ce the base of the valve stem into the opening of coolant spider and apply
air pressure to the coolant system for approximately 20-30 seconds.- Then
while the engine is cold or hot-one can do a thorough check for leaks.
-- I usually place a rag over the hand that is used to-maintain press
ure on the valve stem so as to absorb any blow-back from the release of air
pressure upon completion of test.- The procedure is a quick static test
of the coolant system-that can be performed-any time there is question
concerning coolant system leak integrity.-

Lasse,
More recently I have had a few drops too, intermittently. One thing I found
that probably contributed to the problem was that the sealing washer in th
e pressure cap of the coolant distribution bottle on top of the engine had
perished and there were signs of some coolant loss there. Also, not enough
to even top up the overflow bottle.
I've inspected under the engine after shutting down and could find no signs
of leakage on the inside of the lower cowling, so I still don't know where
it is coming from. There is also the possibility of a few drips from any o
f the lower coolant hoses, or their fittings into the heads.

Have anyone of you had the same problem and replaced parts of the pump....i
f so is it possible to do it without removing the engine from the plane (Or
iginal AeroDesigns Pulsar)

You might try Norther tool. I have seen in their go-cart parts area band b
rakes that look like ours=2C only I have not measured the exact diameter to
be sure they match what those of us that have early kits have.

Does anyone know where to get replacement band brakes for the original areo
designs version ....circa 1995 ?

Hi Mark,
All you need to do is to take your worn bands to you
brake bonding shop and they will bond new linings on to them for you.
Damn side cheaper than buying new bands.

Mark, if you can source a supplier that sells the band brakes with a
slightly larger diameter than those sold at Aircraft Spruce, it would be
good. The original Aero Designs band brakes were slightly larger and the
tabs were slightly longer than found available today. The result is a less
than ideal fit. I've looked many places but never found an ideal source for
the band brakes (even though I still like using band brakes for the 582).
Best,
Mike McCann

Mike,
I have a pair of original bands in very good condition, the
friction material is worn out so will need rebonding with new linings.
