Re: Dirty Radiator?
What model car is it on?
I *think* your talking about the radiator overflow bottle. If so, then yes you should flush out your radiator. It souns like its just dirty water, or maybe some sludge. Do you drive on dirt roads a lot?
Make sure your engine is cold before doing this, or when when you start your car it could crack the block. To flush out your radiator, just take off the bottom radiator hose, and run a hose through it. Put the bottom hose on again, fill it up. I usually do this 2 or even 3 times, depending on how much dirty water comes out the second time. You can run the engine for a little bit, to circulate water out of the engine and into the radiator, so it can be washed out too.
Then you can fill it up with the Green stuff... Dont forget that it needs to be diluted.
