etc Posted December 19, 2008 Share Posted December 19, 2008 1998 legacy L, 2.2L auto, 147K miles How do I flush the coolant (Nothing good seen in the search) Link to comment Share on other sites More sharing options...
98obster Posted December 19, 2008 Share Posted December 19, 2008 I have done a "reverse" flush by disconnecting the driverside hose to the heater core and flushing with a garden hose. Link to comment Share on other sites More sharing options...
Rooster2 Posted December 20, 2008 Share Posted December 20, 2008 If you live in a warm climate, water flush as described by 98OBster. You can also add a can of chemical flush, drive for a few days, drain, water flush, add 50/50 coolant/water to finish the job. Link to comment Share on other sites More sharing options...
etc Posted December 20, 2008 Author Share Posted December 20, 2008 Can I just drain the radiator and then fill it up again? Link to comment Share on other sites More sharing options...
Durania Posted December 20, 2008 Share Posted December 20, 2008 Can I just drain the radiator and then fill it up again? You can but that is not considered a flush but a drain and fill. A flush is like 90obster described which involves flushing out the heater core and everything. Link to comment Share on other sites More sharing options...
etc Posted December 20, 2008 Author Share Posted December 20, 2008 I opened the drain on the radiator but the coolant was coming out very slow, basically dripping. I know it should come out a lot faster than that. Is the radiator plugged somehow? It was full when I looked into it. Link to comment Share on other sites More sharing options...
Durania Posted December 21, 2008 Share Posted December 21, 2008 Did you have radiator cap off? Same principle as the portable gas can, air behind so liquid can go out. You could just disconnect the lower radiator hose. Link to comment Share on other sites More sharing options...
etc Posted December 21, 2008 Author Share Posted December 21, 2008 Yes, the cap was off. It was a drip basically, not a stream. Link to comment Share on other sites More sharing options...
idosubaru Posted December 21, 2008 Share Posted December 21, 2008 the drain plug probably wasn't opened far enough or turned at the right angle? i think the notch in it has to line up right so to speak? Link to comment Share on other sites More sharing options...
etc Posted December 21, 2008 Author Share Posted December 21, 2008 No, the drain plug was completely removed. I drained the radiator on a Loyale one time and I know I got a stream instead of a drip like here. Link to comment Share on other sites More sharing options...
