    You can open the bonnet and check... but the colour is irrelevant.

    The coolant needs to be compatible with MB Spec 325.0 or 326.0 (depending on the engine/year).

    But you should investigate any coolant lose; it's a sealed system so a reduction in coolant level could mean there's a leak somewhere (or a range of othe possible faults).

    There’s none in to check my dad thinks it has to be either red or blue if it’s an aliminum or steel engine?

    I think some are green also.
    But I didn’t think it mattered as long as it meets the requirements
    for your temperature drops where you are.

    green and orange antifreeze are ethylene glycol-based, the difference between them is that they contain different corrosion inhibitor ingredients or additives. While orange antifreezecontains organic acids, green antifreeze has additives, such as silicates, borates and phosphates

    I gave up in the end , far too complicated , so I put beer in .

    Keeps me cool in the summer and I never froze up, even when subjected to the 'Beast from the East' earlier this year .

    You have a leak somewhere then. Also if you fill a system which has some red coolant with blue coolant, or vice versa, the mixture will form a jelly.

    And then Kaitlin...( and not wishing any bad luck on you... )..you will have trouble !!! Better find out the correct antifreeze for your car, and do ( or have your Dad do) a complete drain and flush. Its not that difficult.

    That's what's called " Advance Planning, and Prior Preparation, in order to avoid the dreaded PPP" Personally, I'm a great believer in it !!!:):D:cool:

    My VW was purple! If you can stretch to it go for Mercedes or double check for right spec it shouldn’t be to expensive.

    The important point is that loss of coolant is a serious matter.
    If you run your vehicle with too little coolant, your engine will overheat with disastrous (and very expensive) results.

    So that will be G13 and before that G12 that was pink , both are miscable .

    So simple unlike MB's array of fruit juices .

    Bleeding the air out the golf was a right mare too left it running with the cap off for an hour until it sorted itself out.

    1. ring any MB dealership
    2. ask for parts department
    3. quote your reg
    4. buy the right coolant.

    How would they know what’s currently in the car? It could have been changed
