Blown Head Gasket Snake Oil

[unkymurch]

Well, it's Dec. 5, 2008 and I wanted to give you on update as I promised. I initially used the the Thermagasket product on April 1, 2008. It is now Eight Months later and everything is still holding and I haven't had any problems since. No blockage. No overheating. No regrets. Temperatures are operating and holding normally as if there was never a problem.

(I recently discovered that the previous owner removed the console light behind the radiator warning light. I suppose he had overheating problems, couldn't or didn't want to fix it, so he simply disconnected the warning light to deceive the next buyer. .... sneaky dishonest previous owner).

.... but it's fixed and working now. I even replaced the bulb and socket in the dash console so I can see if my overflow reservoir level is being maintained.)

I read other replies to my original post where different manufacturer's products were used and didn't work. I'm amazed that there are two pages of posts and replies after my first posting. This must be a serious concern of Supra owners.

I'm just posting my results to relay my experience, but it's unbelievable how many people want to "kill the messenger" or accuse me of ulterior motives.

Hey, the product worked for me and I'll continue to post the status just to give my experience with this specific product. Can't wait to post after next summer when it really gets hot in Houston. By then, I would have at least 12 months of using the product.

Until then or until if fails...

Do you know anything about the chemistry of this product?
Sodium silicate is said to work well and is only a few dollars...however,... however "Steel Seal" claims to be polymers, which means plastics, in my mind...
Actually I have a Celica 1987 with a 3S-FE engine, Celica spun off Supra's in 1986, I think.
The 3S-FE engine's basic design must be respectable because engines up to at least a 2000 RAV4 used it's name, I think.

I don't know the chemistry behind Thermagasket. It would be best to contact them directly.

There is a two part liquid component that is poured into the radiator. There are no solid components.

My first installation held 2-3 years and would have continued to hold except that I had a later heater core leak that caused another overheating problem and caused the gasket seal to blow out again. Unless you diagnose and fix the other mechanical issues such as bad radiator caps, leaking hoses, leaking heat cores, leaking water pumps, etc. you'll always get an overheating problem and blow the gasket seal again.

Fortunately, I had the half of the remaining components (since I only used half the amount for the first installation) and reapplied the compounds just like the original installation and just like the first time, IT WORKED!!!!

After having run the car 2-3 years after the first head gasket issue, I felt I was putting too much money into a dead horse and didn't want to fuss with replacing or repairing the heater core, so I scraped the car. If it was something other than the heater core and I hadn't started a new job and needed transportation immediately, I might have tinkered around and done something different, but that was the decision at the time.

Okay, so don't act like you do and assume there are not solids involved.... it emulsifies (see: hardens from chemical and/or thermal reaction), like epoxy.... hence... SOLID.


So, the car finally did tank due to something coolant related and you decided not to investigate? Big surprise there.


Products like this can fix TINY leaks in certain types of seals but can also cause significant damages. Use what you wish but I don't want to see this actively recommended on this board.... you got lucky, most 7M HG's blow in a far more spectacular fashion and most owners are obviously far more demanding of their 7M.

Thread Closed.
