Jeez, Jeff, if you got any advice from me I hope 
it was to measure things and actually find out 
what's wrong, not throw stuff at it randomly.

This system is *easy* to diagnose, if you do it systematically.

The first thing is a precise scond-by-second 
description of what happens to gauge and light in 
the first twenty seconds after turnign the key 
on.  Second is do you have tall old or short new coolant level controller?

>Any suggestions on the pegging temp 
>gauge?  Maybe I’m just ultra low on coolant 
>(wouldn’t that be fantastic.  Sigh).

What would be fantastic would be just diagnose 
the problem and fix it.  It isn't magic.  But it 
means being precise about descriptions and 
eliminating things in a defined order.

Yrs,
