I am watching this thread closely because on Sunday I am heading up
highway 395 to Bishop, CA., where a high of 102F is predicted. Three
degrees hotter the following day. I, too, am driving a 1.9L. A good time
will be had by all. If the cooling system can handle it. If not, then
it's nighttime driving. I went across the desert a couple times with my
old man when I was a kid. Burlap sack of water strapped across the front
grill, bomb-shaped evaporative cooler mounted above Mom's door. Secret
is finding classic courtyard style motorcourt motel with pool in middle.
That, and some cold beer. I know the drill.
