After purchasing heal a seal product and using as directed in their booklet, the product would not fix the issue, a leaking cylinder head gasket. I emailed them for help as advertised and they will not respond to my emails.

The product has not worked and looks like they are trying to get out of refunding money if it does not fix the issue.

Would like to warn other from dealing with this company. I read comments on various websites about this product the majority are from people who have not tried the product. I have tried the product and it has not worked, they do not respond to emails for technical help as advertised in there web page.

    Heal a seal is a big rip off company. but honestly I don't think it is even a real company because when u call it's always the same foreign guy answering the phone I believe he is working out of his house and sitting back stealing everyones money. He owes me $89.90 for the piece of ### gray water that he sent me. The crap doesn't work but mess your car up more. I've been trying to get my refund for over a month but he will not respond to my e-mails nor by phone.

    Heal-A-Seal - Bad product bad customer service
    United States

    This is a scam. The company has VERY POOR customer service, and have failed to refund citing unheard of reasons.

    How did you make enough money to pay the guy stupid fool! You deserve what you get for being dumb enough to think a bottle of something will put material back in a head gasket!

    We purchased this item for a 1992 Mercury Sable that had a blown head gasket or warped head. The product worked as advertised and the car continued for another 20, 000 miles. It does take some effort to use properly and is for a repair of a low value car of a temporary repair on a more expensive car. Properly used I think it is a great product.

    Their advertising is misleading, their manual poorly written, their product DOES NOT WORK, and their tech support person, . .yes ONLY ONE I ever talked to, . .is a jerk!!. They put a loophole deep into the manual about registering the product to get the warranty, . .then at the end of the manual they put in the EXCEPTIONS to the warranty, ANYTHING that can go wrong is not covered!. . .Their website says "can not fail" their manual says "can not fail", .the fact is IT FAILED MISERABLY!!! They tell you you have to send them email, but then they don't respond to the email. .. . spread the word, put this guy out of business!!!

    Agh ! I thought I found the right product for my blown gasket. But after going through this site I am really disappointed. Now I will have to start my search again.

    I have also dealt with heal a seal. I believe that it may work in minor cases of a fisure crack or a small crack. But lets be real a blown gasket forget it. I myself can only say that this is a quess as unfortunately they do not let you know its shelve life is only 1 month at most. I live in a climate where it is minus 30 degrees and do not have a heated garage. I wish they would be up front about this shelve life business before cash is exchanged. Sells would go down much more I would think.

    Well, I was just about to fork out my money. I think I'll just look at a head gasket repair now. I am sorry some people had to shell out before finding out the truth.

    Hey you guys who LOST their money... if you can open an account to re-imburse yourselves I'll happily put $5 in. Everyone else should too as you have saved me over$100.00 with shipping.
    Thanks for the warning.

    Just throw your money away immediately. Heal a Seal has the perfect scam. A big promise and they don't tell you ahead of time that (1) it is EXTREMELY DIFFICULT to do, in fact our vehicle was virtually impossible. (2) They mix it up specifically for you when you order it and it is UNRETURNABLE if you decide you can't use it. (3) It is "good" for only 30 days.
    And I'm sure if we use it and it doesn't work, too bad. Things that sound impossible usually are. Assuming that it really has worked for the people who are satisfied with the product, they are lucky. (But I am not convinced.)
    Bottom Line, the fact is that you cannot get your money back if you decide you don't want to use it, and you are not warned about that until you've ordered it and read the lengthy manual and realize you've been cheated. I'd like to send it back anyway, but it would cost about $13 and I hate to waste more money.

    The only product that I've heard about that can work is made by a company called DIKE...
    Sounds like this loser trying to sell this Heal-a-Seal crap is NON-LEGIT, sitting at his little computer whacking off all day...
    If you happen to come across ANY website that has YELLOW on it then it is NOT-LEGIT. There are so many of them...
    I'm sure you've seen tons of em especially those ones where it says a mom is making $xxx.xx a day/week/month know the Google scam one...
    Those NOT-LEGIT websites all have the same layout...about a mile long getting you to read so much crap to try and get you to believe what they are advertising
    by repeating it over and over for miles...UTTERLY USELESS...STAY AWAY/CLEAR of them...they are all hoaxes!!!
    Myself with my Northstar engine, I have rewired the 2 fans and put them on switches with a 30 amp fuse and can turn them on whenever I feel like it...
    I don't believe in relays...relays BLOW...enough said about relays...
    If a block sealer is going to work you would need to get it into the engine so flushing the radiator and then putting in the product would be a quick way of getting it in there...
    The water pump has a belt with a tensioner on it and this is where I believe is the main problem as the pump is usually not pumping fluid fast enough, so probably getting
    a new belt and making sure its tight to get that water pump pumping the coolant quicker, rather than trickling should help to fix the issue...

    also remember to put each fan on its own separate 30 amp fuse...
    putting 2 fans on 1 fuse will blow that fuse...

    For each fan:
    Get an ON/OFF switch that has 3 connector poles on it...POWER, ACC, GROUND
    1) run the negative wire from the fan to a ground on the car...
    2) run a negative wire from the GROUND on the switch to a ground on the car...
    3) run the positive wire from the fan to the ACC pole on the switch...
    4) run a positive wire from the POWER pole on the switch to a 30 amp fuse...use a single fuse block that has a wire on each end of it...
    5) run a positive wire from the 30 amp fuse block to the battery positive pole (top positive pole if it has one)...

    Now turn on the switch and the fan will spin (and make noise of course)...
    That's what I did for the 2 fans so I don't have to rely on JUNKASS relays that fail...All I have to worry about is a few wires and a fuse...SIMPLE!!

    NOTHING>>>I REPEAT NOTHING, that comes in a can or bottle can fix head gaskets or rebuild your transmission or engine. If you are still inclined to try this product be sure you read and comply with all the instructions, and above all PAY WITH A MAJOR CREDIT CARD, so you can dispute the charge and get your $$ back. Even better, call the "tech support" guy, and tell him that you want to record the conversation because you have a hard time remembering things (it's illegal to tape phone conversations without the persons consent). Then when you dispute the charge you will have all his BS on tape and have no trouble getting your money back.
