Hi folks,

I have a 1992 Legend Sedan LS, and after the BHG was repaired I was told to ONLY use the Green Anti-freeze. I did search and I have read this thread...

"TYPE 2 COOLANT New and Improved"
http://www.acura-legend.com/vbulletin/showthread.php?t=57673

....but it seems inconclusive.

Lately I cannot seem to get all the air out my cooling system, so I am having the problem where at idle (when warmed up) the RPMs cycle from 500 to 2000 RPM (approximately). A few other symptoms have led you folks in the past to suspect a leaking Power Brake Booster as the cause for the air getting into the system, but I really don't know. In the past I could follow the air purging procedure and get the idle stable, although in a few days or weeks the cycling would return.

I wanted to make sure that if I lowered the level of my coolant too far, I could top it up, so I went to buy some more of the Green anti-freeze. But at a local Honda dealership (there are no local Acura dealerships) the parts guy said there is no more Green anti-freeze, that I should be using the Blue anti-freeze.

Is this true? Does anyone have any more information or opinions about this? Please comment! :-D

The level in my overflow/reserve looks fine, by the way, but it is awfully "dark"! :-O Not the bright limey green I was accustomed to, but more of a brownish green! I didn't see any "slick" but I wonder of the color indicates oil in the coolant, or just rust or old age or something! :-(

Although my temp gauge still sits faithfully unmoving on the second index up, I wonder if my HG is leaking/blown again. :-( I guess I could have a compression test done. I'm due for a smog check, which was one of the reasons I'm trying to stop the idle cycling, but I don't know of a trustworthy mechanic here in Santa Cruz for the compression check.

So is it okay to use the Blue Anti-freeze or would it be better to track done the Green? Is the Green still available?

Any ideas, comments or suggestions would be very welcome! Thanks for looking!

I don't think Honda would change the formulation of their anti-freeze...the important consideration is whether the anti-freeze is silicate-free. Maybe call Acura of Augusta, tell them you are from this board and see what they say about anti-freeze? Jason should be happy to help, he's answered a lot of my dumb questions in the past.

Thanks duck! I'll call Jason.

Any other opinions, comments, ideas or suggestions!

What do you all think of the dark green coolant? How about my inability to get the idle stable?

Thanks for looking!

Here's an interesting thread:

I'll be calling my "Acura Guy" here shortly. If he isn't busy, I'll bring this up with him.

The blue and green coolant are compatible with each other.

We had this discussion a long time ago...I ended up finding green coolant still in some places.

Doesn't BMW use blue coolant?

I called the car's original dealer back in Connecticut, Executive Accura, and they said they still have the green anti-freeze if I really want it, but that the blue would work fine too. I'm tempted to get more of the green for now, so I'm not changing the color I look at.

I guess when I do flush, I'll switch to blue!

And sorry for the huge SIG, I don't know how it got switched to that big one, it should be about half that size! (There - I have fixed that!)

Thanks for the comments and help folks!
