Sonata Coolant Change??
 

Anyone know what the proper procedure for doing a coolant change on a 2006
Sonata is? "Draining" the coolant as instructed in the manual results in
about 2 1/2 quarts making it out of the system - basically, the radiator,
and the hoses. The rest of the coolant - about 6 quarts - the lower part of
the engine, and heater core, etc. Is there a drain plug on the engine
somewhere to really do the job that's not mentioned? Please Help.[/align][/align]Thanks
