Overheating is a critical concern that can arise from various underlying problems, including:

• Coolant leaks

If the engine overheats, it can cause severe damage, including warped cylinder heads or a blown head gasket, leading to costly repairs.

In the worst-case scenarios, some owners have reported complete engine failure. This catastrophic issue can occur due to a combination of the problems mentioned above. Factors contributing to engine failure include:

• Neglecting regular maintenance
• Ignoring warning signs such as oil pressure warnings
