You will get many more posts on this but I will give it a shot.
For me it takes 3 people.
Elevate the van 4 inches at the front.
Take off the grill and expose the bleed screw at the top left corner of the
rad (when you're looking at it) and get the correct wrench to loosen it off.
Loosen it and hand the wrench to helper #1
Go the back of the van and have a supply of coolant mix ready to go. Open
the filler tank (not the overflow tank) and prepare to pour.
Explain to helper #1 that their job is to tighten the bleed screw when there
is a full stream of coolant being forced out -- no air bubbles -- no
hesitation -- a full flowing stream.
Tell helper #2 that their job is to start the van and hold it at 2000 rpm
--- if you don't have a tach use yours ears and tell them to hold it when it
sounds like 'that'. Explain to them that if they let of the gas it will send
coolant flying in your face while you are trying pour it. Emphasise this
point.
Now that helper's 1 and 2 are ready. Go to the back of the van and get ready
to pour coolant into the resevoir.
Have helper #2 start the engine and hold it 2000 rpm --- you pour coolant in
as fast as you can until Helper #1 closes the bleed valve and you can pour
no more.Slap the pressure cap on. It all happens rather quickly. Tell your
helpers to stand down.
Go have a beer.
Cheers,
Doug
