I've got a fairly simple way of telling if there's air in the system, and
bleeding it.......
Drive the van around untill the thermostat's open, then park it in your
driveway or wherever you can stop for a bit, with the nose up hill....let it
run a bit. Then shut off the car, pull the upper grill off, and take the
bleeder nut all the way out of the radiator. Did coolant gush out? Be
careful, it's hot. If coolant gushed out, you MAY be okay. Leave it off (or
put it back on), but leave it parked there for a while untill it cools down.
After a while, (maybe you ran and ate a sandwich), open up the bleeder again
(Engine off), and insert a small length of hose that's just the right
diameter to have space between the outside wall of the hose and the inside
diameter of the bleeder hole....attach it to your favorite funnel, and start
to pour in some coolant. Is it taking some? Then there was air in your
system. Fill it up until it's coming out a bit, then recap it......drive
around.....park on a hill....eat a sandwich, etc etc etc untill it no longer
takes any.
This system just worked out really well for me in the past, the bently
methods are confusing and just don't seem to work.....
