So I literally just pour it into the system. Om assuming it boils out then?I think I discussed that in the video ... where the B12 goes, although I didn't aactually show that process.
In case you missed it, take that big black hose off the upper nipple and put the B12 in the open end of the hose ... reinstall it without the clamp, start the engine after 1/2 hour or so, repeat a few times.
Be sure to start with a hot engine ... you might remove the hose clamp when it's still cold .... and don't forget to clear out the liquid by starting the engine between doses.
B12 is very ... uh ... aggressive and it can harm paint ... so don't spill it.
It won't (maybe) hurt you (maybe) unless you (maybe) bathe in it (maybe) .... but I recommend that you use protection to keep it from going through your skin to attack your kidneys.
I used it a lot ... even to clean parts and had my hands in it .... but I don't suggest you do that.
