I would recommend checking your coolant level religiously. I do it nearly every fillup. Judging from the thermal mass of the engine and the size of the radiator, I'd say there's very little tolerance to lack-of-coolant over- heating. In other words, if you let it run low or lose coolant, the engine will overheat in no time and warp the heads. By the time it's over, all you'll really know is that the head gasket is blown.
