Filled up the coolant and observed it for couple of days. Drove around 75 kms in that time. Situation is not great - coolant loss continues but at a lower rate. One of the hoses with a spring clamp has wet area around it. That is one of the places where it is leaking. Unfortunately no screws to tighten it, just a spring clamp. Either I have to get a new hose + clamp or at least a clamp with a screw. With 99.rpm stopping Punto and Linea spare parts, I don't have any way of getting the spare parts in my place. I may be able to get a generic clamp of that size from a local automobile shop and try fixing it. For that I have to drain out the coolant first and then try the fix. At the end if the new clamp does not fit or fails to stop leakage or if the hose itself has a problem I will have to drive to Manickbag FASC at Hubli. Around 12 ltrs of petrol + 1 day wasted in the effort. What a pain it has become now But the real problem is - I am not confident that FASC will be able to give me a definite solution. Manickbak service station at Hubli has some Tata legacy; they believe in trial and error instead of trying definite methods like pressure testing. Though it is possible to pressure test the coolant system I doubt Manickbag at Hubli has equipment and expertise to do that. Please give me suggestions about how to verify coolant system leakage - how can I verify leakages have been fixed for sure. Now I am really a frustrated vehicle owner (won't blame Fiat though - it can happen with any car for that matter).
