WEAVER99 Posted January 29, 2009 Share Posted January 29, 2009 I had just purchased a 99 GS300, and was wanting to use seafoam to clean the carbon out. I've read alot of guys that have done this and it works good. My question is, it says to run it through your brake booster line, for you that have done this on your GS, where exactly was the line located at that I need to use? Or is there a better way to do it? I appreciate the replies, and so far really enjoy the GS. Quote Link to comment Share on other sites More sharing options...
SKperformance Posted February 2, 2009 Share Posted February 2, 2009 Your going to need someone to help you along with this to show you the location of the brake booster as if not reinstalled properly will leave you withouth brakes. It is the large black dome on the firewall. Quote Link to comment Share on other sites More sharing options...
