July in Ohio isn’t just about fireworks and cookouts—it’s also prime time for your car’s cooling system to get pushed to the limit. With temperatures climbing and engines working harder in the summer heat, one of the simplest yet most crucial maintenance steps you can take is checking your coolant.

But how often should you check it? And what signs should you watch for? Let’s break it down.


Why Coolant Matters Year-Round

Coolant (also called antifreeze) isn’t just for keeping your engine from freezing in the winter—it’s also vital for preventing overheating in the summer. Your engine generates a lot of heat, and without a properly functioning cooling system, it could overheat fast, leading to breakdowns and costly repairs.


How Often Should You Check Your Coolant?

We recommend checking your coolant at least once a month , and especially before long road trips or during extreme weather like July heatwaves.

If you’re not sure when it was last checked or topped off, swing by Sun Valley Auto Repair. We’ll take a quick look and let you know if you’re in the clear—or due for a flush or refill.


FAQs: What Ohio Drivers Ask About Coolant

Q: What are the signs my coolant is low?
A: Look for a dashboard warning light, engine overheating, or if your heater or A/C isn’t working as expected. You might also notice a sweet smell under the hood or coolant pooling under your vehicle.

Q: Can I check the coolant myself?
A: Yes! Once your engine is cool, open the hood and check the coolant reservoir—there are usually “min” and “max” level lines. Make sure you never open the radiator cap when the engine is hot!

Q: How often should coolant be changed?
A: Most vehicles need a coolant flush every 30,000 to 60,000 miles , but always check your owner’s manual—or ask us. We can check coolant condition and let you know if it’s time.

Q: Can old coolant damage my engine?
A: Absolutely. Old or contaminated coolant can corrode the radiator, water pump, and engine parts. It also loses its ability to regulate engine temperature, increasing the risk of overheating.
