DRAINING, FILLING & BLEEDING 

COOLING SYSTEM PRECAUTIONS 

Use only coolant additive G12 meeting specification VW 774 D. G12 coolant is Red in color. G12 must not be 
mixed with any other additives. If fluid in expansion tank is Brown, this is an indication that G12 has been 
mixed with another type of coolant. In this case, coolant must be changed. 

G12 coolant additive may be used in older vehicles when original coolant is drained and cooling system is 
flushed. Contaminated coolant must be drained immediately and cooling system flushed. See SERVICING . 
Also, if radiator, heat exchanger (heater core), cylinder head or cylinder head gasket, have been replaced, flush 
cooling system and replace engine coolant.
