Just about to change coolant in my 89 syncro westy as well... my (very)
trusted mechanic says he usually puts in one gallon of non-phosphate coolant
and adds water to fill, which I guess would be a little more water than
coolant in the end.  Since we live in a very moderate climate... 55 degrees
to 95 degrees year round, what does the list think about that?  Should I
insist on a 50/50 mix anyway?

Also changing the gear oil since the bus is an 89 and I don't know the
history... my guess is that it's never been changed.  They normally use
Valvoline 80-90 wt Hypoid gear oil.  APE Service says it is rated for GL-4
and GL-5 use.  I've been following the threads about this and have pretty
much decided that GL-4 is the only way to go, but what about this?  It is a
hypoid, which is the correct one, right?  Don't know if it is a synthetic.

Thoughts?
