Josh,
Using Evans HD coolant and a 210F thermostat, and I'd bet you'd be fine. Maybe add a set of ARP studs.
I just read an article about the Evans HD Coolant. Jack Evans is recommending to use a thermostat 20F warmer than normal. Program the rad fan to activate at 235F and use the Evans HD Waterless Coolant. Jack says one could expect a 3-8% increase in MPG.
I found the article yesterday in a diesel trade paper at a truck stop in Kansas. If I can find a link, I'll post it later.
Edit: Forgot to say: I returned from Death Valley where it was 80F. I never removed my "winter front end" (pipe insulation to cover grill opening and clear tape to cover the VW emblem). The temp guage never moved off the "190" mark (center).
FWIW,
