Feel the fluid and smell it, if sticky and sweet, it's just old coolant, if slick and smells like motor oil, do a block test, this will determine if hydrocarbons(Exhaust gases) are present in the coolant, if yes, a head gasket or intake gasket may be leaking, this kit can be puchased at all parts store.
