I believe it should cycle, based on some google searches last summer. The system is generically known as a CCOT (Clutch Cycling Orifice Tube) type.

Beyond that, I don't know much about it. Mine doesn't seem to cycle when idling, like (i think) it did last year. Vent temp only in high 40's, at idle(90°F ambient). But low 30s on the road, with fan at mid setting. So I guess it's chilling OK. I don't idle it much anyway.
