Is the B-12 Chemtool the same thing as Sea-Foam? i will be soaking my intake in this while my head swap is under way and the Chem tool was only $2 vs seafoam being $5. Is it the same stuff or comparable?

Also, what is the capacity of our coolant system with the 2000 5.3l radiator, not the 34", being in Texas i dont think it would hurt if i just put a jug of dex-cool and the rest water but i was just wondering how much would it take to yield a 50/50 mixture.

 

I believe the B-12 is a little more aggressive than the seafoam. I have used both but prefer the spray GM top engine cleaner for cleaning the intake and carbon in the cylinders/valves as I pull the plugs and spray it into the cylinders. I would test soaking your heads in case it wants to discolor the aluminum. I think either would work for your purpose.

 

I am not soaking my heads in it, just my intake. I run seafoam through the brake booster and I was wondering if the B-12 will yield the same results. I will not be touching my cylinders with this stuff, just the intake. I dont think i will clean the cylinders as i am pressed for time.
