Thread: Coolant Recovery Tank Help

just fill it with water.

this^^

I'm still running straight water in my car. Probably should take care of that soon.....

Sounds like someone might have mixed some green stuff with the dexcool. Personally I'd drain the radiator and flush with water a couple times and fill with fresh universal coolant before winter.

It's normal from my experience for an open to air container with 14 year old dex in it to be goopy.

I'd pick up a little coolant, either dex compatible or anycolor. Mix or mix your own to 50/50 and you are all set. If you want a cracked coolant res, use water. Water expands and without you telling us where you live..I assume the north pole.

Yup

Bill is the man around here but I'm pretty sure you don't want to mix green with DexCool unless something has changed that I don't know about. I use the universal stuff just to be safe because I've bought a couple used GM cars in the past that have had all kinds of red clay looking crud in the radiator and the overflow container. I was told that this problem occurs from mixing green antifreeze with the original DexCool. If I'm wrong which is possible mixing green with Dexcool will be new to me...

Yeah universal is compatible with dex. I'm pretty sure if you take even the latest conventional green and latest dex cool, and mix them, they will sludge. That happened to someone on the forums, they took it to get it flushed with green, months later a different tech said it would be okay to top it off with dexcool since it's whats recommended for GM, and it sludged.

Someone in my family did that to their dex cool system, it was a mess...

To the OP, Bill is right that the recovery tank will sludge without coolant contamination due to air. What's important is to make sure it wasn't mixed. Pop the radiator cap and make sure it's fine in there. If not, I'd just add universal and wait til spring to do a thorough flush with a cooling system cleaner. You'd flush/backflush it well with water, then top off with the cleaner and more water if needed, and drive it like that for a while. After a few weeks it will dissolve a lot of junk.

any color is a brand bill was talking about.

Well basically there's a spot where one fits, but Pontiac decided not to put one in there. Just go to an auto parts store and ask for a filter for a regal. I asked for one for a 2003 impala since we have one and I knew it fit since I tested it first.

Under the cowl at the bottom of the windshield. It's a good idea to install the water deflector cowl while you're there. http://www.grandprixforums.net/showt...ter+floorboard

Actually ...it is what is written on the container. It's not necessarily the brand. I've seen it written on many different manufacturers.

Guys, when I've seen Dex/green mixed it's usually a brown mess. Haven't seen it gunk/oat up, but then..maybe I didn't wait long enough. Another thing to keep in mind is most any color coolants have a green tint to them. It's easy to mistake it for green if the system was clean and flushed when it was added.

I meant brand like dex is a brand. I guess maybe not the best choice of words on my part
