The coolant will change colour if and when when it's overheated.
green but looks pink? change colour? no offence but it comes pink in the bottle. if its green it comes green.
ok basically there are 3 different coolants for falcons;
R13C 500ml blue as used in EA-ED
R150 1L red/pink used in EF-EL (i would recommend not to use this if you have it flush it out properly and use R133)
R132/R133 1L/5L green use in EF onwards
be carefull with the ratio of coolant with the R133/R132 too higher concentrate will cause problems. use about 33% in 6cyl and 50% in V8s. use about two bottles with the blue and 1 bottle if you use red.
