Fill the rad with water ( close the drain valve first ) run the engine to operating temp. and move the heat control to heat ( you don't need to turn the fan on ). Let it cool down a bit before removing the rad cap and drain the rad again... then fill up the cooling system with the right mixture of coolant... done. (in reply to w3civic) Post #: 2

RE: Cooling system flush - 2/19/2007 10:34:54 PM    shnormo   Posts: 204 Joined: 2/11/2007 Status: offline Get some new Dex Cool on your arms.  It will burn your skin.  It's got a high acidity level from the get go.  It eats away head gaskets and rusts out the radiator pretty quickly.  It says it lasts 100,000 miles yet I have not seen a car with 100,000 miles with dex cool that still tests good.  Why do the 3.1 and 3.8 always have coolant leaks from the intake manifold.  The 4.2L and the 2.2L is notorious for having blown head gaskets.  People who power flush their coolant systems and put in either the green or the preston universal anti freeze test good till their recomended intervals.  (Green is recomended for 60,000 and the prestone is good for 150,000) _____________________________ http://www.cardomain.com/id/shnormo05 It's better to burn out than to fade away.
