Thread: Winterize Spark

  1. #1

    Winterize Spark

    Hello
    In Germany it going to be winter.
    So I have to winterize my Spark.
    I bought glysantin g12 to flush the Spark and avoid corrosion.
    I also bought storage spray wich protect the inside of the engine of corrosion.
    But I didn't know where to spray in the storage spray.
    Do you have an idea?
    Thank you and regards
    Jannik from Germany

    What exactly is your 'storage spray' for the engine? Brand and product name?

    What is glysantin g12?

    Glysantin G12 is radiator antifreeze. Its the fluid which cool your engine.
    My storage spray is this one: http://www.liqui-moly.com/liquimoly/...cument&land=gb

    Do not use antifreeze that contains ethylene glycol on watercraft.

    Propylene glycol is the non-toxic anti-freeze for PWC use, when needed.

    Refer to the Spark owner's manual or service manual for the winterization process.

    What is so bad if the antifreeze contains ethylene glycol?
    the Glysantin g12 is made for the new aluminum engines. So nothing should happen. Or?

    Ethylene glycol is poisonous. When you put your watercraft back in the water the antifreeze gets into the environment. Even dumping it on the ground before you go riding causes the ground to become toxic. Ethylene glycol tastes sweet, so pets and animals that lick it can be sickened or die. Ethylene glycol does not naturally decompose quickly, it remains poisonous and leeches into the groundwater. All around nasty stuff.

    Propylene glycol is not toxic, safe for the water and ground, and for animals/fish. Does not cost a lot, no reason to not use it for watercraft winterization. Propylene glycol antifreeze is widely available, also used in aluminum engines as coolant. There is no advantage to ethylene glycol over propylene glycol for your purposes. For watercraft winterization, Ethylene glycol is essentially the 'old nasty stuff we used before we knew better'.

    Your 4-stroke Seadoo engine has a sealed closed loop cooling system with the factory antifreeze already inside. You are not touching that coolant system, you are only asking about adding antifreeze to the few parts of the watercraft that are exposed to fresh or salt water, not the actual engine cooling system.

    Oh ok. So if i would use the toxic one, nothing can happen with the engine. But it doesn't matter because my antifreeze isnīt toxic according to the details on the package.
    Yes. The regular service get my spark. So I do nothing with the cooling system. The antifreeze I want to flush though the jet to avoid corrision on the waterbox and exhaust.
    But thank you for your extensive description

    The previously linked web site included this info, apparently for the Glysantin G 012 coolant;

    ethylene glycol.....70-80%..107-21-1diethylene glycol...10-20%..111-46-6
    sebacic acid.........1-5%...111-20-6
    sodium hydroxide....1-1.5%..1310-73-2
    If that is correct, your G12 coolant is indeed the toxic stuff.

    Hmm. Ok. My first run after the winter would be on land anyway. So no fishes would die
