I'm going to change the coolant in my recently purchased '90 Vanagon
Westfalia .  I have  the Texaco non-phosphate antifreeze.  I am not sure
how to drain the system.  I have a Bentley manual.  As I understand it,
I should remove drain plug(s) from the cylinder heads and open the
coolant expansion tank cap. From that point on I get a little confused.
If anyone on the list can help to clarify Bentleys explanation I will
appreciate the help.
