Changing relay did worked but the temp needle started bit erratic behavior so started to investigate deeper, checked for hose clips. Topped up expansion bottle couple of times and it turned out to be overflow from bottle. checked for radiator cap and it was new had not issues earlier. I was seriously confused for whats' wrong why temp needle move bit up in crawling traffic.

finally i did the idle run test at home in morning , culprit was located as pump leaking causing cavitation in system and expansion tank throwing up.

here is pictorial of situation.

BELT was bad as well

pump impeller was not so bad, but the flange housing was at end of life.

From which salvage yard in Karachi, you got this item?

Was pre-diluted ready-mix coolant present at time of such end of Life water pump and Flynge?
