I'm following this link and have to say- I don't understand what is all
the fuss about. One cannot fill the rear reservoir completely full.
About half full is right, there needs to be room for expansion. The
front (inside) bottle needs to be full all the time. but a properly
function pressure cap and air tight hose to the expansion tank will keep
it topped up.
I NEVER take out the grille and bleed the radiator. Even last month when
I put in a different engine and quite a bit of coolant was lost, I just
filled it up at the pressure cap a couple of times, started it up and
refilled it with the engine at operating temp and revved up to about
2000 (had someone else hold it there), and put on the pressure cap and
hose before releasing Then tighten down the valve on the thermostat
housing.
Sure, there is a little .air in the system, but it will self bleed out
in a few cycles. Maybe this might be a big problem with the a/c on in
the summer if it was 100 degrees outside. But I doubt it.
I've never owned a 1.9 gas car and they might quite possibly need more
care than this. The same procedure works for my 82 diesel, however.
I'll check the radiator bleed valve sometime. I realize that large
amounts of air might not be able to get out of the radiator without
bleeding. Maybe in our climate 1/2 a radiator is enogh to give me good
cooling.
