Re: 4kq coolant flush

Well, I have some stuff that I got from my old mechanic (German 
Performance), and he said not to leave it in there more than necessary to 
finish what you're doing and drain it and flush it all out until it's 
gone.  It's not from Prestone, although it's in a yellow bottle (aren't 
they all!).

I also heard that the stuff (flush) has some kind of chemical reaction 
that results in increased pressure in the system, which should not be 
maintained for extended periods.

Does anyone else know what I'm talking about, because I sure don't?!
