    Default Flushing Coolant System

    I need to flush my coolant system. Is it advisable to do it yourself or should I get the power flush done? I have done it before myself, but I have over 157,000 miles on my engine. Advise?? Thanks!!

    I'm a DIY on this one. I don't see any advantage to commercial powerflushing over a Prestone flush and fill kit.

    I'm with unplugged. I don't think the difference between the two is significant enough to pay for it to be done.
