hello all ive got a 1.8 tdci lx 2008 galaxy with pink coolant/ antifreeze. Without thinking i topped it up with perhaps 3/4 pint of blue antifreeze. Will this cause any problems? Ive checked on the internet but so far with mixed answers..?? Some suggest this can create a gel which blocks the system, some say this is not a problem...also read its impossible to flush out the mixture... My gut feeling is to just get the coolant drained and changed. Thanks in advance
