Wouldn’t be surprised if the manufacturer came out with a new product, actually the same product relabeled. Labeled “designed to clear automobile heater cores”.

But perhaps not, that would make sense…

Well,went through procedure yesterday using CRL. Temp out of the vent is  
now at 135 deg. instead of 80 deg. which is way better when you are in  
Wisconsin. I did read the instructions and it said you could use it in a  
coffee pot. So, I figure why not. We will see if it stays working. I think  
possible I put a lot more time and effort into it then my mechanic did. I  
flush it for maybe two hours one direction then the other.

Thank you guys again for your help.

Best of luck. Yeah, you definitely need that 135 degree output where you live.
