    If you're trying to remedy what you think is a blown head gasket, according to my engine building experience and 2 years of similar posts in here, you're SOL.

    The GM recommended Bar's tablets or #12 powder are for assembly nuisance drips and block porosity sealing. Not gasket repair.

    Mechanic in a bottle will not fix a bad head gasket. Do a search and read Rfishings lengthy post.

    I really hate to say this, but don't get your hopes too high. It's only temporary.

    All statements are true so now since you have some time on your hands(no car to fix) it will help you to do as Ranger instructed on reading Rfishings lengthy post. It might help you incase of future issues.

    I used it on September 23, 2010 and have driven thousands of miles already and not one time has it overheated on me. I was also skeptical, and so was my mechanic.. He actually LAUGHED at me.. Well, guess what... He just used it on a customers truck and was completely impressed. Especially after he and his employee's all laughed because I was going to use it. AWESOME PRODUCT!

    And even if it only is a temporary fix, it sure has lasted quite a while, and if it happens again.. I will use the other half that I got.. BUY IT!

    Email me if you have any questions. I am located in Kansas City..

    Give it some time. You've only used it for a month and a half. That stuff cannot fix pulled threads. Glad it is buying you some time, but it IS temporary. Please keep us updated even if/when it fails. It will be interesting to know how long it lasts.

    This always seems to happen w/ thermagasket... they come back immediately (or in a month or two) and say 'it worked!' then don't ever come back to say 'it's still working 9 months later!' (because they either sold the car or got it fixed and are ashamed to report back that we were right)

    You know, I'm just gonna add to this phenomenon as well.

    I don't believe in this crap any more than most of you. I mean, how can some liquid in a bottle fill a leak and retain 200psi compression? Not very logical.

    Anyway, earlier this summer (July) my girlfriends brother's 160k mile 1998 Ford F150 4.6 was diagnosed with a bad headgasket. Typical frequent unexplained coolant loss, running warm. The mechanic gave him his options, including physically repairing the headgasket or trying Thermaseal, which the mechanic told him may or may not buy him time but customers have had success in the past.

    Since he really doesn't care about the truck and doesn't find it to be worth shelling out the money for the HG replacement (she's getting rusty/OHC engine so labor is higher), he gave the Thermaseal a shot.

    Lo and behold, similar to the claims in this thread, it worked. It's his DD transportation to work and hunting vehicle on the weekends. It's still chugging along just fine. When (not if) it fails again, he'll deal with it then. But for now, he's pretty happy with what he got out of it.

    :shrug: I can't explain it. It still really doesn't make sense to me but you can't argue results. The stuff actually does well for what it is.

    it does 'work' for other cars but for N*s with head bolts pulling there is no amount of magic potion that will fix the problem

    Here is the theory behind it.

    Why pay Thermosgasket $300 for it?

    OR you can buy it at the pharmacy.
