Ranger Posted June 29, 2009 Report Share Posted June 29, 2009 Drain plug is a little hard to get to. You can't get all the coolant out. Using a shop vac in the blow mode and putting the nozzle in the surge tank will help blow a little more out. Also easier if you premix it before replacing the coolant.

Texas Jim Posted June 29, 2009 Report Share Posted June 29, 2009 Just to add a note... As Ranger said..it would be a little easier to premix it before you add the coolant. I would use distilled water to in it. Link to comment Share on other sites More sharing options...
rek Posted June 29, 2009 Report Share Posted June 29, 2009 "trick's".... A short section of "Broom Handle" with a slot cut into one end, makes a "tool" for the drain plug... rek Link to comment Share on other sites More sharing options...
