Volvo P1800 Clutch Fluid + Alternator Belt Changed

Last week, happened to check the reservoir of my Volvo P1800 clutch, found the fluid inside to be really dirty.

Then, whenever I ON the air conditioner of my Volvo, there is a squeaking sound. The mechanic told me that the belt is loose, but there is no room for it to further tighten it, and have to get a shorter belt.

Yesterday, having some extra time, and no rain, I was finally able to send my car to the mechanic. I bought the belt previously from spare part shop, cost me RM20+.

I requested Dot 4 oil for the clutch fluid replacement. Not sure how to bleed it clean, so better leave the job to the pro. Cost me RM80 for the work + dot 4 fluid from the mechanic.
