Doug, I always follow the manual myself (I guess it is a left over from
my aviation mechanics training). At least that way if you have a
problem people can't say "Why didn't you follow the manual?" However
the 2.1l cooling system is pretty nice in that in most cases it will
self bleed over the course of a week or so. I have never had one of
these have a large air bubble that caused an overheat problem. I have
had this in the earlier vans (83-85 1.9l) so bleeding them right is very
critical. On the later vans (86-91) while it is important to bleed the
system properly, they are more forgiving than the earlier ones. Two of
the main things I do when I install an engine is to turn on the front
heater to full blast and also listen for the radiator fan to go on and
off (low speed). I need to have hot air coming out of the front heater
and I need the radiator fan to cycle a few times before I say that an
engine is properly installed. This saves me from putting in a new
engine and then having a customer fry it within the next month. I have
been very successful with this procedure. So far in 11 years I have
never had anything bad happen because of an overheat on a recently
installed motor or even a head gasket job.
Take your time, read the manual, do things in a step by step manner and
you will have very good to great results. Get in a rush, do things in a
sloppy or half way manner and you are just throwing your money and time
away. Just my advice.
