    I've always used Repco green coolant for all my raddy flushes, etc. I've had the car six years and never put red coolant anywhere near it. I just checked the level before and it's turned a light pink colour. No coolant in trans fluid or vice versa, no oil in coolant or vice versa, all seems perfectly normal except for the pinkish coolant. Any ideas?

    it sounds like your radiator is ####ed internally, leaking tranny fluid into the cooling system

    The radiator is only a couple of years old. No I don't have a photo, Edals.

    Can the forum solve this mystery? Yes we can!
    Has it got a strange smell?

    The trans fluid level hasn't dropped at all, it's always exactly on the full hole at the top of the cross hatches. Wouldn't the extremely high coolant pressure cause some coolant to be present in the trans fluid?
    Tranny fluid is perfectly pink and as clean as the day I put it in (gets serviced every 40,000 k's)

    Tastes like trans fluid lol, if u get a leak on your driveway, you can tell if it's trans or engine oil, same with distasting coolant, I've known mechanics to do it, teacher at the mta teaches it. It's a quick easy way to know. Not saying drink a cup, just a taste on the tip of ur tongue then spit it

    riiiiiiight. well i deal with that stuff daily, so i reckon i will give it a miss.

    yes OP, if trans fluid goes one way, then coolant would go the other. your trans fluid would have water in it which would make it milky and your trans will snarl at you when you select different gears (going from park to drive, going from stationary to 10kmph etc)

    my guess is the guy who mentioned rust. i reckon the coolant is probably getting to the end of its life, the dye is changing colour and rust from the block and any other cast iron bits is making it go that colour.

    time for a flush maybe?

    There have been quite a few cases where the turbine in the water pump starts to rust..
    Result is pink coolant..

    Well ari666 I hope you're right. Coolant must be as old as the radiator, about two years. Think I'll go Nulon this time.

    The ethylene glycol green radiator has a sweet taste and is highly poisonous.
    You should never have pets or little kids around when doing a radiator flush in case they drink some.
    Kills birds that drink the overflow from radiators in car parks.

    Well I did a one thousand Km round trip on the long weekend and the coolant got redder and the trans fuid level dropped.
    So, took the radiator to Repco still uder warranty and fitted a replacement radiator.
    Now they'll test my old one and re-imburse me if it's faulty. I can't think of any other way trans fluid could get into the coolant.

    If trans fluid got into your coolant is be worried it flowed both ways.. You don't want coolant in your transmissions..
