Why Your Vehicle’s Thermostat Is More Important Than You Think
Although often overlooked, your car’s thermostat plays a critical role in maintaining engine performance and preventing costly damage. So, you may be driving back in forth to work. Or just driving to our vibrant Martinez Downtown area. Either way, you want to make sure you get there without trouble. And your car or truck’s thermostat is key to that. So, in this post, the experts at Meineke in Martinez explore why your vehicle’s thermostat matters, how to maintain it properly, and what signs suggest you have a faulty thermostat.
What Your Car’s Thermostat Actually Does
Basically, your thermostat regulates your engine’s temperature by controlling coolant flow. When the engine is cold, the thermostat remains closed to allow it to warm up quickly. However, once it reaches optimal operating temperature, it opens to let coolant circulate, preventing overheating.
How to Maintain Your Thermostat
Thankfully, maintaining your car’s thermostat doesn’t require much effort. First, always check your coolant levels during regular maintenance intervals. In addition, schedule coolant flushes as recommended by your manufacturer. Furthermore, inspect for any leaks, rust, or corrosion around the thermostat housing, which could signal early trouble.
Signs that You have a Faulty Thermostat And It Needs Repair or Replacement
Even though the thermostat is a small part, ignoring issues can lead to major engine problems. So, here are the most common red flags to watch for:
-
For starters, your temperature gauge fluctuates or stays unusually high or low.
-
Next, you notice poor heater performance during cold weather, which may signal a stuck-open thermostat.
-
Afterward, steam or coolant leaks around the engine could mean the thermostat is stuck closed.
-
Eventually, your car may go into limp mode or trigger a check engine light due to irregular coolant temperatures.
