Why is my Suzuki Bolan overheating even after replacing the water pump?

I recently installed a new water pump in my 2015 Suzuki Bolan, but the engine still overheats, especially during long drives o r in traffic. The coolant is full, and there are no visible leaks. Could the problem still be related to the water pump o r something else?

Air Pockets in the Cooling System: After replacing the water pump, air can become trapped in the cooling system, leading to inadequate coolant circulation and overheating. Its essential to properly bleed the system to remove any air pockets.

Thermostat Malfunction: A faulty thermostat may not open correctly, restricting coolant flow and causing the engine to overheat.

Radiator Issues: A clogged o r damaged radiator can impede coolant flow, reducing cooling efficiency.

Coolant Quality and Level: Ensure that the coolant is at the proper level and of the correct type. Using the wrong coolant can lead to corrosion and inadequate heat dissipation.

Recommendation: Have a qualified mechanic inspect the entire cooling system, including the thermostat, radiator, and coolant levels, to identify and address the root cause of the overheating.
