Drain it and install the blue stuff, and inform them that only  
Pentosin is ACTUALLY phosphate and silicate free.

It's not like you need to do it this second, day, week, or even  
month- but the "green stuff" is "low phosphate", even the stuff that  
claims to be phosphate FREE. If you don't believe me- check out  
Prestone's website where the slimeballs (pardon the pun) spin a  
wonderful tale about why they should be able to mis-label "low"  
phosphate coolant.

What is the name and location of the shop, please?
