The valve is new within the last few years and does not leak, but  
just to be safe, I completely bypassed the core anyway.  2 feet of  
heater hose (more than required) and two bypass caps are less than $5  
and the job is done.

My concern re: the heater was not as much providing heat to the  
cabin, but to provide additional cooling capacity to the engine.  It  
was never a particularly effective option in the past, but I felt  
safer having it.

Pullman is in a rain shadow.  Our summer is typically highs from  
85-100, lows 50-60.  The only rain is in the form of thunderstorms,  
which bring with them hail and often fire.

We do see rain fairly often in the spring, but that's passed.

Of course, I'll be driving to California along the coast highway.  I  
fully expect to see plenty of fog and some rain.  The return will be  
on the eastern side of the Oregon Cascades, so I expect a hot and dry  
trip.

I think I got the timing back where it belongs, so I'll go out and  
test it later today when it warms up.  It's only 57 now, hardly  
stressful temperatures.
