Coolant Level Low , Small puddle on drip pan

I have been keeping my Tanis heater plugged in all the time and the leaks have totally stopped.

I guess it's just the temperature/shrinkage difference with the hoses.  Glad it's stopped though.

Honestly, if you top off the coolant you could probably just go fly and as things warmed up the leak would fix itself.  But then it might recur if it got cold again.  It's pretty easy to feel the lines for wetness, find the leak, and tighten the offending clamp.  I used to have leaks at the beginning of every winter.  Replacing all my spring clamps and honking down the other clamps when installing after my hose change seems to have cured it so far.

My annual is coming up in April and the A&P has planned to do just that.  I figure since I've got the heater I'll just leave it on for the winter, if nothing else but for the engine.  It sure starts easier since I've been using it.

Plane flew for 4 hours yesterday.  No leaks while warm.  The condition is obviously what you folks stated which is greatly appreciated.  I will pull the bottom cowling off and find the source.  Thx !

Pulled the top and bottom cowlings off and reviewed all hose clamps.  I saw no obvious dripping, other than where the rubber hose meets the coolant reservoir.  The clamp is a spring clamp, no tightening.  The two materials are rubber and plastic.  While leaving the bottom cowling off, Put rags on the ground to hopefully provide a "tell" where the drip is coming from.  It may just be the rubber hose meeting the plastic reservoir (bottle.)
