I have a suzuki mehran 2006 which is reducing water in reservoir bottle, bottle gets empty after 2 days. Hoses seem fine and radiator also went for leak testing it doesnt has any leak was serviced three months back. Last week i suggest my mech to check water body if it is problem and car is reducing water he says i cant see water leak but he opened all timing chain fan belt pulley timing pulley and then he said everything ok only pulleys need to be washed with petrol to remove dirt and grit then he did and said me to check the car the next day it started to reduce water i told him he said aik do din check karein phir mujhe dikha dein phir kuch karte hain. Now my fan belt is giving some noise and when i put water on that fan belt the noise finish for ten seconds again comes. Head gasket is ok radiator is not chocked but water is reducing. Xulfiqar bhai @ekdrifter bhai tell me im in problem and these retard mechanics say aik do din check karein and summers are already here and im afraid that it might heat up. Performance is also decreased. And my car knocks, when i accelerate car knocks.
