Coolant Level

[Hawkeye]

After replacing the bad Roush "O" ring I have been really watching the
coolant level in the overflow tank.

I don't see any leaks, can't smell any more coolant, but yet the level
in the overflow tank is slowly going down.

Anyone else notice this or have any ideas?

It's a 2013 Stage 2 Roush. About 2500 miles on her.

There was a post not too long ago describing the same issue. The owner could never find the source of the leak but knew it was leaking as he had to continually top off his coolant tank. Dealer was stumped. And then they discovered that only under load, it was leaking from the bottom of the engine. It seems Rousch drills the bottom of the engine to run a coolant line and the crack in the engine was only 2 inches away. Long story short Ford took back the raptor. This owner only had it less than 1000 miles.

Thanks, but I hope that's not it! Fingers crossed......
