Hey guys, got a quick question about doing a coolant flush. I bought my car about a month ago and it hasn't had the LIM replaced yet. The oil looks good and I don't see coolant leaking anywhere, so I plan to replace that myself (as well as new valve cover gaskets, new tstat, supercharger gasket, supercharger oil change etc) in the spring. I would do it sooner but I really don't want to do it until its warmer.
However the coolant itself looks quite old and dirty (somewhere between orange and brown in color if I had to guess), but I don't see any evidence of the "oatmeal" texture sludge that I've read about, at least from popping open the radiator cap. My question is should I have the coolant flushed right away, or can I just wait for spring when I do the LIM gaskets?
