5 Common Causes in May & June
When Oklahoma temperatures start climbing in May and June, it’s not just the pavement that gets hot—your car might, too. At our auto repair shop in Yukon, we’ve seen an uptick in overheating issues across the OKC and NW metro area, especially in high-mileage vehicles and cars overdue for service.
If you’ve noticed your temperature gauge creeping up or steam under the hood, don’t wait. Here are the five most common reasons your car might overheat—and what to do about it.
1. Low Coolant Levels
Coolant (also known as antifreeze) helps regulate your engine’s temperature. But when it’s low—or leaking—you’re at serious risk for overheating, especially during Oklahoma’s hot summer months.
Signs to watch for: Sweet smell from the engine, puddles under your car, or the heater not working properly.
Tip: If you live in Yukon or NW OKC, it’s a good idea to check your coolant levels monthly and top off before long drives.
2. Broken Thermostat
Your thermostat controls coolant flow. If it’s stuck closed, coolant can’t circulate and your engine can overheat quickly.
Good to know: A faulty thermostat is a quick, affordable repair—if caught early.
Why it’s common: Rapid temperature swings in Oklahoma during spring can cause thermostats to fail earlier than expected.
3. Faulty Radiator or Fan
The radiator and its fan are crucial for dissipating heat. If your radiator is clogged or the fan isn’t spinning, your engine won’t cool down—especially in stop-and-go city traffic or while idling at Yukon’s Main Street lights.
What you’ll notice: Rising temps while sitting still, but normal temps while moving.
Pro tip: A radiator flush or replacement fan motor can resolve the issue fast.
4. Leaking Water Pump
The water pump pushes coolant through your engine. If it’s leaking or failing, circulation stops—and overheating follows.
Symptoms include: Squealing noises, steam from the hood, or orange coolant puddles.
Quick check: Look under the front center of your car for drips, especially after parking overnight.
5. Damaged Hoses
Hot weather weakens rubber hoses over time, especially in older vehicles. Cracked or bulging hoses can leak coolant or even burst.
What causes it in OKC: Intense sun exposure and high engine bay temperatures during May and June.
Helpful tip: Inspect hoses every oil change for wear or soft spots, or swing by our Yukon shop for a quick look.
