    gunk block seal fantastique

    15 years ago
    Je l'ai essayer sur mon cavalier 96, il y avait une fissure d' ou on pouvait voir un peu de prestone bouillir sur le bord d'une bougie et une boucane j'échappais de l'échappement seulement lors du démarrage. UN mécanicien m'as dit que c'était la tête de moteur qui étais fendue. Je me suis informé à un spécialiste et il m'as dit que ca couterais $1200 pour changer la tête ou $600 si je faisait la job moi même. Vu la valeur de mon auto j'ai mis de coté cette solution. Ne voulant pas attendre que mon moteur me saute dans la face je me suis informer au près d'un vendeur de pièces automobile et il m'a recommander un bouche fuite en poudre qu'on rajoute au prestone. Je l'ai essayer et ca n'as pas marché. En parcourant le site de Canadian Tire, j'ai découvert GUnk block seal et je me suis rendu au magasin pour me le procurer je l'ai comparer avec les autres produits en magasin et je me suis aperçu que dans les produits qui étaient offert qui spécifiais qu'il pouvait convenir pour les culasses (tête de moteur) . Je l'ais essayer et ca marche vraiment en enlevant la bougie du cylindre fissuré, car la pression du cylindre aurait empêché le produit de se bloquer la f endure.

    AWESOME STUFF

    17 years ago
    i bought this stuff thiking it wouldn't work very great but was worth a try, amazingly this stuff works as said, my van has a blown head gasget and with this stuff I usally buy 1 maybe 2 a month at most works way so much better if you just dump it in and leave it it, but I have put 10,000 km+ on my van and still going, can't really do long distance's without having to add water or antifreeze in the winter, but it does get you around, usally do 2 to 3 hours of highway driving before you have to add more water (summer) or anti freeze (winter). other wise if you just go place to place in town 2 or 3 times aday you usally good for a month, about a tank and a half to 2 tanks of gas (90$ gas tank to fill) chevy venture van year 1998. can't complain 95% effective!!

    Yes, I recommend this product.

    Q: can this be used to seal fuel system parts? I would like to restore the rusted tank of a vintage moped. I plan to remove the loose and surface rust by hand, but I would like to seal it with another industrial product and thought this might work.

    Q: How easy is it to apply this stuff? Planning a road trip and would like to be prepared for just about anything. If I crack my block during my trip... how hard is it to pull over and apply this stuff to get moving again?

    • A: This Block Sealer is most effective if used according to manufacturers instructions. Engine coolant is to be drained from system into containers. Then fill system with water, add sealing product, run vehicle to operating temp., shut down engine, drain water from system, add "New" 50/50 mixture engine coolant, if this isn't possible, add the coolant you had drained from the system. Safety first : Always be very cautious when removing radiator cap.
