Dear friends, Please help me to clarify the following. 1. Engine coolant capacity is 7.6 L. If one use 50-50 specification one has to use 3.2 L of coolant. If one uses 60-40 ratio one has to use 7.6*0.4=3.02L I have checked many others coolant replacement and the amount vary drastically from 1L to 3L. Why it is . Let me come to my case. My invoice says 3L is purchased. They given back me ~400ml of coolant. Why they didn't use the 3 L fully since actual requirement is minimum 3.02L. Other thing is he told me that they have used 75-25 ratio in that case 1.1 L should be unused 7.6L-7.6*0.25). Now what service adviser told me was since they poured concentrated coolant after some use the level will come down and p0ur distilled water. Now the above three facts doesn't merge to a point. It is contradicting each other 2. I paid 82.67 for brake fluid replacement. But I checked with others and they spent 700+ INR. There is some thing fishy. It looks like they haven't replaced it where they told all fluids are replaced. More over in my case they used DOT4 goldencruiser. Who asked them to use that. Is a problem with availability of Fiat specified brake oil. The amount used is 250 ml.
