Coolant Loss resolution

In looking at the pressure cap on the coolant header tank it looked like it had a bad seal so I orddered a new pressure cap. I will say I was shocked at the price ($75.00 plus shipping). Hopefully Rotax will cover it under warranty since it definately was bad. Anyway, serviced the engine with coolant and installed the new cap and flew it on a short trip of 2 1/2 hours (round trip)for the infamous $100 dollar hamburger. Checked the coolant systemm after returning and everything was perfect with no coolant loss. So the moral of my story is if you are loosing coolant and can't find a leak, you might want to check out your header tank pressure cap.
