I added about a 1/2 bottle of new stuff and it worked fine But Ive never seen that in a car before I am going to flush it out Where is the plug Im assuming right underneath it?

Did it just turn brown? Or are you just now noticing it?

Things like age and fluid contamination, not to mention sitting int he engine bay can cause that. Sometimes you can resurrect it with a good scrub, but often then only way to get it pretty again is to replace it.

It probably doesn't have a drain plug.

Thanks its probably a combination of all of the above It really hasn't been driven for 2 years Basically sitting on the street maybe once a month . We are very close to the ocean but I dont know if that would have any effect although its seems to always be windy here or windier then inland Maybe the cap wasn't put on tight at some point. I just started driving it popped the hood & couldn't believe my eyes Looked disgusting & I didnt see a valve to empty it so Ill srcub it out funny thing is its working just fine thanks
