There was rust in the hoses so I'm replacing the upper and lower hose along with the radiator. I'm worried that there might be rust and particulates in the block. What is the best way to remove all that stuff?

Previous owner of the block must have ran straight water with no tstat.<br /><br />With the block drain plug removed it was pretty easy to flush and fill. I ran prestone super radiator flush for a couple hundred miles along with distilled water. Then replaced heater core + radiator + water pump + tstat + hoses. <br /> </font> </td></tr> <tr bgcolor="#dedfdf"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>Vortech Saleen</b> <br /><small>Member # 7494</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2019,11,21,9,34,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> I didn’t pull the freeze plugs but I did removed the hoses to the radiator and the heater core and flushed with garden hose until water ran clear.

I use the Prestone Flush+Cleaner. Use one bottle with straight water.. follow instructions and use for an extended period of time. If you feel that it should be done again, then repeat. <br /><br />When finished with the chemicals, make sure you flush out the engine with water like you have previously done.. the prestone does leave a residue. <br /><br />Also, make sure you disconnect the heater core and flush with the hose in both directions. I like to hook the gardening hose to one of the heater core lines and a separate clear hose up to the other heater core line to see when debris has stopped coming out of it, then reverse the hoses to back flush. <br /><br />Good luck. I know this process can be long and tedious. <br /> </font> </td></tr> </table></td></tr></table> <br /> <br />
