Have you touched the rear window after an extended period of highway driving? ;-)

Installed it, got rid of the shut-off valves, and found that I could not turn off the heat.  Talked to Dennis - turns out you have to have the water flow direction correct for the valve.  Reversed the hoses and now the tubes are cold when they are supposed to be.

Now, with perhaps 1500 miles on since going through 5332 I find the car to be surprisingly cool.  But, of course, we live in the Pacific Northwest - and that helps a lot.  Flip side, it was pretty easy to insulate the bottom of the tunnel, if one has the console out.
