These problems can be caused by issues with the radiator fan, serpentine belt, and temperature sensors.

1. Failed Radiator Fan

The radiator fan cools the engine by blowing air over the radiator.

If it stops working, the engine can heat up quickly, especially in hot weather or during heavy driving.

Reasons for fan failure include blown fuses, bad relays, or a broken fan motor.

Regular checks can help catch these issues early.

2. Damaged Serpentine Belt

The serpentine belt powers parts like the water pump and alternator.

If it’s worn, cracked, or breaks, it can stop the water pump from circulating coolant.

This can lead to engine overheating.

Look for signs of wear and replace the belt as needed.

3. Faulty Temperature Sensors

Temperature sensors keep track of the engine’s heat.

If a sensor fails, it can give wrong information to the engine’s computer.

This may cause the cooling system to work improperly, leading to overheating or unnecessary cooling.

Replacing faulty sensors quickly can help keep the engine temperature stable.

Regular maintenance on these parts is key for a healthy engine and to avoid costly repairs.

Engine-Related Issues

Engine overheating in the Hyundai Nexo can be caused by several issues.
