jaks14 174 Posted June 25, 2014 Report Share Posted June 25, 2014 Now I'm. Ploughing through the bodywork side of the mk2 vr I'm wanting to start on making the engine run a little smoother and give it a bit of probably a long overdue service and clean out generally..My question is what's the best way to give the coolant system a good flush out? Can I run the engine whilst having a hose maybe into the header tank to circulate the water while I have a hose off the bottom of the radiator?? Or is the best way to just drain it all off via a bottom rad hose then refill and drain again a couple of times until I'm happy?Advice would be much appreciated on what yous have done etcjimmys oakvr Link to post Share on other sites
