Subject: Re: bleeding coolant system?
2.1L i guess... not real need to raise the 2.1 for bleeding...
To remove coolant:
open front rad and thermostat bleeder, remove exp. tank cap.
to get to those 2 drain plugs under the engine, you need to remove the lower
protective tins under the engine, but that is sometime impossible due to
rusted bolt... (drain plug location)

That will get rid of about 6-8 liters.., unplug the heater line that connect
to that big "bypass" metal coolant tube on the left, in front of this one...
another 2 liters shoul comme out... now, most of the rear section of the van
is empty.... remove the spare tire and disconnect the 2 main coolant line...
this will empty the front rad and the 2 main line...
Most of the coolant is out....
Close everything...
To bleed, your choice:
Raise (or not) REAR of van for a faster result...
open all bleeder, including front rad, rear heater under the rear seat and
thermostat bleeder...
Note:REMOVE the rear thermostat bleeder... pass the 2 small tabs and make
sure it's not coroded!!!!! clean this one.. put it back.
pour coolant in the exp. thank, the rear heater will be the fist to drip...
close this one after, the front one (if van is high enough) will be the
second one, close it. fill the tank, squeese most line to get some air out,
start engine at idle... let it run, you can give some rpm but it's not a
must... wait until thermostat open up and look for some steady coolant flow
at rear bleeder...
close all bleeder, put tank cap... bring a 13mm ratchet and go ride the
van...once in a wile, open front rad bleeder...
You can also do the same for the rear bleeder... but that is only for peace
of mind, the 2.1L will self bleed...
That is all...

Hi All,
I'm trying to bleed the coolant system.
Is there just the two places to bleed?
The Radiator & the Thermostat housing?
I see in the manual that the system should be drained
just below the heads? Is this on the block?
Mostly though, What's the trick with the bleeder on the thermostat housing?
I can turn it counter clockwise about three turns,
but nothing comes out?
Not coolant, not air?
Does it also need to be pressed?
Need a heads up on this one fer sure !
Thanks,
John C...
