What to Do If Your Engine Overheats
Immediate Steps for Drivers in Nashville, Antioch & Brentwood
An overheating engine doesn’t give you much time to think.
One minute you’re sitting in traffic.
The next, the temperature gauge is climbing. Fast.
If you’re driving in Nashville, Antioch, Brentwood, or South Nashville, knowing exactly what to do when your engine overheats can mean the difference between a manageable repair and catastrophic engine damage.
Here’s what to do — in order — without panic.
Step 1: Pull Over Safely and Shut the Engine Off
As soon as it’s safe:
Pull off the road
Turn the engine off
Turn the A/C off
Driving even a short distance while overheating can warp engine components in minutes.
No exaggeration.
Step 2: Do NOT Open the Radiator Cap
This is where people get hurt.
A hot cooling system is pressurized.
Opening the radiator cap too soon can release scalding coolant instantly.
Wait at least 30 minutes before touching anything under the hood.
Step 3: Watch for These Critical Warning Signs
While the engine cools, look and smell:
Steam coming from under the hood
Sweet smell (coolant)
Coolant puddles under the car
Warning lights on the dashboard
If you notice white smoke, that may indicate coolant entering the engine — a serious condition explained here:

Step 4: Check Coolant Levels (Only After Cooling)
Once the engine is completely cool:
Check the coolant reservoir, not the radiator cap
If coolant is low, do not assume topping it off fixes the problem
Low coolant almost always means there’s a leak or failing component.
To understand why this matters, read:
👉 How Being Low on Coolant Affects Your Engine
Step 5: If It Overheats Again — Stop Driving
This part is critical.
If the engine overheats again after cooling:
Do not keep driving
Do not “try to make it home”
Have the vehicle towed
Repeated overheating causes exponential damage, not gradual wear.
Why Engines Overheat in the First Place
Most overheating issues are cooling-system related:
Coolant leaks
Radiator failure
Faulty thermostat
Bad water pump
Cooling fan problems
And once overheating starts, damage can escalate quickly.
Here’s what overheating actually does internally:

Check Engine Light
Rough running or misfires
No-start conditions
Internal engine damage
