In the same vein the thermostat on my '85 had stuck open. Which I agree is better than stuck closed but I finally replaced it and I get about 1-2 mpg better gas mileage. Which is what I expected and why I did it.

Not a terribly difficult job, pmail me if you want details.

Now on to fixing the horn which honks when I turn the wheel.

After 40 or owning a Van it's fix, fix, fix.
