Flushing antifreeze on a 2006 kia sorento - 2003 Kia Sorento

This procedure makes a bit of a mess and requires catch pans but it is the best way to flush a coolant system without cutting any hoses or adding a flush kit.


If your radiator does not have a drain plug is to remove the LARGE lower radiator hose and drain the anit-freeze. (Even if it does have a drain plug the steps below are the best way) You then plug the lower radiator hose connection on the radiator and have a 2nd person add water to the radiator with a hose. They will need to place a rag over the fill port for the radiator and flush the block until you get clear water from the lower drain hose. Once you get clear water drain off the fresh water by unblocking the lower radiator fitting and flush the radiator. Once you get cleanwater from the radiator connection, reconnect your lower radiator hose. (Tighten the clamp!) Then add your anti-freeze. Remember there will still be a some water in the block so do not be afraid to keep your anit-freeze / water ratio a tad higher because the left over water in the block will dilute it slightly.
