Hey my name as well is Joshua. I have a Chevy impala 2005. I've recently noticed there is an almost sludge looking stuff in the radiator resivor and the cerpentine belt will make the squeaky once it's warmed up and it randomly do it and sometimes when it does my lights dim. I've noticed a black build up of something around the pillows and where the belt goes. What should I do? And can u flush your coolant with out the flush stuff couldn't u use water or something
