I've been running Sierra Coolant in my '91 Golf for about 9 months now, and
while I've had unrelated cooling system problems (impact damage to the
radiator) I've found that the car generally runs cooler than it used to.
Prior to the first installation, I completely flushed the cooling system
with clear water (complete drain, refill w/ water, drive it up and down the
highway to get the thermostat to open, drain again, repeat once)

I'm very happy with the results I've had!
