When the fluid boils the cockpit could be filled with steam. That would
certainly get your attention!

What if the overflow bottle was mounted on the cockpit side of the firewall
where it was visible at all times?

| Subject: | Re: Rotax 914 Turbo Warning Lights |
I was once comfortable checking the overflow bottle level. not any more. A
friend had a small leak in one of his hoses and the first indication he had
was an overheat indication. When he landed his over flow bottle was at the
normal level but he had no coolant in the pressure reservoir.
Over time the coolant had slowly leaked ender pressure and on cool down the
system sucked in air instead of coolant from the reserve bottle.
I now check for leaks, bottle level and coolant in the pressure tank.
