This sentence infers that carboxylate is a base solution as the other two are, but in fact it is just a trace additive such as nitrates or other forms of organic acids. I researched the msds's of several OAT based coolants and they all list ethylene glycol as the main ingredient in quantities of 88-98% by weight. Not one msds of any OAT or Nitrate stabilized coolant even lists carboxylate(an organic acid) as an ingredient; likely due to its use as a trace product. The term is also used in a similar manner in the paragraph that follows it in the ILM. Status: Implemented

CAN WE PLEASE GET COLOR ILM's. I have color in my presentations, but the students only get black gray and white pictures. From the instructor side could we please get color ILM's for all periods and semesters for our students. They all agreed that if the price went up for ILM's they wouldn't mind paying the extra. Being able to see different colors in diagrams make learning easier for the students. Status: Implemented
