    Steel Seal: what do we know to elaborated best application approach

    Good for you ! How much miles has it made after the treatment ? Was the K-Seal patch still good?

    Steel Seal: what do we know to elaborated best application approach

    4. My Steel Seal application procedure on Prius gen 3 for cylinder to coolant system head gasket leak. I assume the initial state is with Toyota coolant in the system and environmental temperature is positive . Drain the coolant and flush the system with water 4-5 times. That is, each time...

    Steel Seal: what do we know to elaborated best application approach

    On more point to consider : its is hard to get ph of 7 after vinegar . The amount of baking soda should be adjusted precisely, which is quite tough . If there is a little excess, pH quickly goes to high alkali values, which is again not good for red LLC. Therefore after vinegar followed by...

    Steel Seal: what do we know to elaborated best application approach

    Hi Toocan, thank you for you interest. I will finalise the post with remaining data. Your procedure looks to me correct. I have just a few comments: (1) heater core: If you run the application process with the heat and vent both at max in the cabin, there is no practical need to bypass the...

    Steel Seal: what do we know to elaborated best application approach

    3. Steel Seal film dissolving test The sodium silicate films achieved in the previous hardening experiment are the result of a superposition of gelation and curing of the sodium silicate. The differences between the deposited film samples is due to the uneven rates of the two processes in...

    Steel Seal Hardening tests: results and discussions The images below show the results of the evaporation and hardening test for four samples. The main deposition occur within the grove of the aluminum can while nearby wall and curved bottom of the can are also partially covered with thin film...

    Steel Seal: what do we know to elaborated best application approach

    Curious about the final result. Some people clamp the inlet pipe on the heater core but that may cause an engine overheat. That largely depends on a specific engine. In my case, I had an idea to bypass the heater core but finally don't apply this, just run it at highest heating temperature...

    So it is acidic. Perhaps it can live with OAT based coolants (pH ~7.5). This is drastically different from Steel Seal, which in my experience is not compatible neither with OAT no IAT coolants. And it is not based on sodium silicate. Interesting how long does it last ?

    Hardening test: sample preparation and methods Samples were prepared with Steel Seal to coolant or water weigh ratio of 1: 6 , representing the ratio in the engine coolant system during the treatment. The acidity is measured with a pH meter unless stated otherwise (pH litmus stripes with...

    Steel Seal: what do we know to elaborated best application approach

    Steal Seal Hardening Tests: Background There is a couple of youtube video showing Steel Seal curing with an open flame. The result is a fin white film deposition. The film is highly brittle. The first series of tests was used to find conditions for a less fragile film deposition. According to...

    Steel Seal: what do we know to elaborated best application approach

    Filed application experience The car is Toyota Prius gen 3 (XW30) with 2ZR-FXE 1.8L engine prone of head gasket (HG) failures. For what follows it is important to note that the coolant system capacity is about 7 Litters , however only 5 L can be drained while 2 L remains in the system. 1...

    Steel Seal: what do we know to elaborated best application approach

    There have been many post and threads on successful and disastrous results of Steel Seal application for leaking head gaskets. The main issue of all these communications is that almost nobody describes the exact procedure used and the coolant. Even a reference of following the the "official...
