Low Coolant Light On? Signs, Risks & Fixes
If your car coolant level is low or the coolant light comes on, don’t ignore it! Coolant (or antifreeze) prevents your engine from overheating, especially in Texas’s hot weather. At Fifth Gear Automotive, serving Lewisville, Argyle, McKinney, Crossroads, Castle Hills, and Frisco, we’ve helped many motorists who’ve had coolant issues before they turn into expensive repairs.

Can You Drive with Low Coolant?
Technically, you may, but you really shouldn’t. Low coolant can lead to engine overheating, which may cause severe damage like a blown. head gasket or even a seized engine.
If your coolant is low:
- Pull over and check your coolant level (only when the engine is cool!)
- Check for leaks – puddles under the car may be a sign of trouble
Top it off if you can get coolant (use the right kind for your vehicle) - Visit a trusted auto shop if the coolant is low, there’s a reason
Why Did My Coolant Light Come On?
Your coolant warning light means the engine temperature is rising, or the level of coolant is too low. It could be due to:
- A coolant leak in the radiator, hoses, or water pump
- A malfunctioning thermostat preventing coolant from flowing properly
- A faulty radiator cap that can’t hold pressure
- Ignored coolant maintenance – aged coolant loses its effectiveness
If your coolant light is on, don’t risk it. Stop by Fifth Gear Automotive for a coolant check and system inspection before small issues result in large repairs.

How Often Should I Check My Coolant?
To ensure your car operates smoothly:
- Check coolant levels with each oil change (at least every 3 months)
- Flush and refill coolant every 30,000–50,000 miles, depending on your car
- Check for symptoms, including overheating, leaks, or sweet smell under the hood
At Fifth Gear Automotive, we offer coolant checks and flushes to ensure your engine remains in top shape. Driving through McKinney, taking a road trip from Frisco, or hauling in Cross Roads doesn’t have to mean driving around with an ill-performing cooling system if it’s well maintained.
