Top causes in Pakistan:

Use of plain water → leads to rust and corrosion

Cheap coolant brands → clogging and deposits

Overtightened o r loose belt → bearing damage

Low maintenance → ignoring early signs

Mechanic’s Tip:

Always use coolant with corrosion inhibitors

Replace coolant every 1–1.5 years
