Monaro CV8 losing coolant.

[psycho sport]

Is there a common fault or issue with the LS1 Monaro losing coolant? Had to top mine up a fair bit over the last few days. No sign of leaks or anything and the quantity isn't massive, an inch or two on the coolant reservoir.
Anyone else had this?

Thanks for the replies. Will have a lol tomorrow. Cheers
