Q - I want to empty out the coolant so I can replace the after-run thermoswitch, heater control valve and put in some fresh new coolant. So, is there a specific way to do this, or do I just open up a handy hose and let it drain? I know, make sure it's cool first. Does anyone recommend a specific coolant, or do they fall in the "all the same" category? Rob Winchell 91 200Q 87 4kCS
