coolant leak
I have a slight coolant leak that I can not find where it is leaking, does
know of a coolant pressure tester that will work with the Rotax coolant
system?

I don't know about a tester, but I had a tough time getting my hoses tight enough to not leak, especially from the water pump and into and out of the radiator.

coolant leak
The only place that I see coolant is in the bottom of the cowling
and the hanger floor under the back of the bottom cowl.

I'm digging back here, but as I recall there is a weep hole on the bottom of the water pump that monitors the water pump seal. Might want to check and see if it's wet.

"O" rings can leak if not seated properly between the intake manifold and engine case.

My Rotax 912 ULS will loose a little coolant from various places while sitting in a hangar where temperatures are dropping below freezing. A chat with Lockwood indicates this is not unusual.

The water pump has a ceramic seall and a weep hole on the bottom of the pump. During times of cold temps the different contraction rates between different metals and seals can cause a very small leak. This is usually limited to a tablespoon or so of coolant. This can be quite normal and can be on and off. So long as you don't have a large puddle on the ground I wouldn't worry.

...and then went back to wiping OIL from my lower cowling!

That's OK, Perry with the money we save on gas we can afford more maintenance than Lycoming owners!
