      Exclamation Fluid leaking near serpentine belt.

      I have a swift ddis 1.3 2013 model. The car started making some hissing noise 2 days ago and it increased today and the belt also started making noises. On opening the engine bay I found out that some kind of liquid is leaking into the auxiliary belt. It seemed like engine oil first as it was black but then I found out traces of green coolant around the alternator and ac compressor and on the belt. Now I am confused that what is this liquid and how did it get there (PS: the engine oil and coolant levels look just a tad bit lower). I tried to run the engine and scanned the bay for leaks but couldn't find any. But then after I shut it down I could see vapours from the bay.

      Also scanned to codes using a obd reader but all was clean. Please help in pinpointing the issue.

      I don't think the green stuff is coolant but refrigerant from your AC compressor. The refrigerant is always mixed with a green fluorescent tracer to detect leaks. I think your AC compressor is giving up.
      When did you service your AC last time?

      I got the air conditioning system checked before the 2018 summers around March. the mechanic said that there was sufficient ac gas and the evaporator coils were clean. So no work was ever done to the ac and the cooling is also fine.

      If you have a UV light you can shine it on the green colour and it should glow if it is refrigerant.

      Ok I visited the service centre.
      The water pump bearing was broken and was leaking out coolant.
      The service guys quickly asked to shutdown the engine because this could have jammed the pulley and cause belt to break. So I have got the water pump assembly replaced and now everything seems fine. The service guys also mentioned that the adjuster bearing is also making a little noise but has no ply as of now. But it is in my to-do list for next service.
