* Poor engine performance: The engine may not reach its optimal operating temperature, resulting in incomplete combustion, reduced fuel efficiency, and increased emissions.
* Increased wear and tear: Lower operating temperatures mean increased engine wear due to incomplete lubrication and slower warm-up.
* Difficulty warming up in cold weather: The engine will take significantly longer to reach operating temperature, potentially leading to increased wear on the engine components.
* Problems with emissions: The catalytic converter may not function optimally at lower temperatures, causing emissions problems.
While you *could* theoretically install a lower temperature thermostat, it's generally not recommended for a daily driver. If your engine is overheating, the problem is likely elsewhere and needs to be addressed properly, rather than simply lowering the thermostat's temperature setting. Things to check include:
* Coolant level: Is it low? Is there a leak?
* Radiator: Is it clogged or damaged? Is the fan working correctly?
* Water pump: Is it functioning correctly and circulating coolant properly?
* Thermostat: Is the *existing* thermostat sticking open or closed?
If you are experiencing overheating, diagnose the underlying cause before considering any modifications to the thermostat. Using a lower-temperature thermostat as a solution without addressing the root cause is likely to lead to further issues.
