In regards to bleeding the coolant, I've read the Bentley manual and I
opened the valve on thermostat.  I didn't open the bleeder screw on radiator
because I believe the manual stated open the bleeder screw if you can't get
the thermostat valve open.  So which way should I do it, should I open both?
I didn't see any coolant come out of thermostat valve should I have?  Why is
it so important for the Rpm's to be 2000?  All info is appreciated.  Thanks,
Marcus
