When we made that 1800 mile trip through the smoky haze of a big fore year
and 106 degree temperatures, I had just had the van puke about a quart and a
half of coolant a week previously, so I was on edge the whole time.
If I'd known about the later fan switch with the lower opening temperature
I would have installed one. Instead I put a bottle of Ceramiseal in the
coolant and drove off with my wife and younger son in the van.
It has not leaked a drop since, but the long climbs through Idaho and
Wyoming had me worried all the time...
Not any more! ;)
Seeya, Jake
