jimmy57 Posted January 25, 2017 Share Posted January 25, 2017 I'm still a fan of Cascade( or other brand of automatic dishwasher soap). Soft water in my area and so many other things won't quit sudsing after many flushes so I can get onto a distilled water flush an then getting coolant in it and out of my bay.

Matt Saunoras Posted January 25, 2017 Share Posted January 25, 2017 I use Fleetguard Restore. I forget where I got my last case, probably on eBay. Quote Link to comment Share on other sites More sharing options...

Steve Mutter Posted January 27, 2017 Share Posted January 27, 2017 I have used the fleet guard stuff and thought it worked very good. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted January 27, 2017 Share Posted January 27, 2017 Proper flushing procedures are outlined in TSB 08-23-1 AND it is important to flush with VC-9 Iron Cleaner. Quote Link to comment Share on other sites More sharing options...
lmorris Posted January 27, 2017 Share Posted January 27, 2017 I have always found I got better results when I started to run the engine with the radiator drain removed from rad, and feed water into the degas for 5 minutes, before a complete drain and adding coolant. I have always felt that the oil and EGR coolers don't get properly flushed with just the hose pushing water through the engine. Quote Link to comment Share on other sites More sharing options...
Matt Saunoras Posted January 27, 2017 Share Posted January 27, 2017 I usually run the engine with a hose in the degas and the drivers side block drain out. If you rev the engine and water violently shoots out of the block you know you're flushing good. 1 Quote Link to comment Share on other sites More sharing options...
BigWalt Posted February 21, 2017 Share Posted February 21, 2017 either simple green or cascade works for me along with VC9.....I take thermostat out, driver side block drain, and let it run @1200 rpm for hours with garden hose in degas bottle....gotta get the motor hot....cold motor doesn't do the job good.
