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.
