If your car overheats in Florida, safely get out of traffic, turn off the engine, and let the vehicle cool. Do not remove the radiator or coolant-system pressure cap while the engine is hot. If the temperature rises again, you see steam or leaking coolant, or you do not know why the vehicle overheated, have it inspected rather than continuing to drive.
After more than 30 years of towing and roadside experience, I have one important piece of advice about overheating: do not try to squeeze a few more miles out of an engine that is telling you it is too hot. A tow is usually much less expensive than major engine damage.
1. Recognize the Signs That Your Car Is Overheating
The first warning may come from your dashboard. Your temperature gauge may move toward the hot or red area, or a temperature warning light may appear.
However, the dashboard is not the only warning.
Signs of an overheating vehicle can include:
- A temperature gauge moving into the hot or red range
- A high-temperature warning light
- Steam coming from under the hood
- A sweet coolant smell
- Coolant leaking underneath the vehicle
- Loss of engine power
- Unusual smells from the engine compartment
If you notice these signs, take the warning seriously. Continuing to drive can turn a cooling-system problem into much more serious engine damage.
2. Get to a Safe Place and Stop
First, concentrate on getting out of active traffic.
Use your turn signal, turn on your hazard lights, and move to a shoulder, parking lot, side street, or another safe location when possible.
Once you are safely stopped, turn off the engine.
If you are on I-4 or another high-speed roadway, do not stop in an active travel lane unless the vehicle gives you no other choice. Your personal safety comes before the mechanical problem.
If the vehicle becomes disabled in an active traffic lane or creates an immediate roadway danger, call 911.
3. Do Not Open a Hot Radiator or Coolant Cap
This is one of the most important things to remember.
Never remove a radiator cap or pressurized cooling-system cap while the engine is hot.
The cooling system can remain under pressure after the vehicle stops. Opening it while hot can release extremely hot coolant and steam and cause serious burns.
Give the engine plenty of time to cool before anyone attempts to inspect the cooling system.
AAA also advises drivers to let an overheated engine cool before checking coolant and specifically warns against removing the radiator cap while the engine is hot. You can read more in AAA’s vehicle overheating guidance.
4. Should You Turn Off the Air Conditioning?
Yes. If you notice the temperature beginning to climb while you are still moving toward a safe stopping location, turning off the air conditioning can reduce some load on the engine.
However, this is not a repair.
Do not turn off the air conditioner and then continue driving for miles while the engine remains overheated. Use the opportunity to reach the nearest safe place to stop.
5. Why Do Cars Overheat?
An engine needs a properly working cooling system to control its temperature.
Common causes of overheating can include:
- Low coolant
- A coolant leak
- A damaged radiator
- A faulty thermostat
- A failed cooling fan
- A damaged hose
- A failing water pump
- A broken or slipping belt
- Other internal engine or cooling-system problems
You do not need to diagnose the exact cause while stranded beside the road. In fact, roadside guessing can sometimes make the situation worse.
The important thing is recognizing that the vehicle is overheating and avoiding additional damage.
6. Does Florida Heat Cause Cars to Overheat?
Florida heat can put additional stress on a vehicle’s cooling system, especially during summer traffic, long periods of idling, or stop-and-go driving.
However, hot Florida weather by itself should not normally cause a properly functioning modern vehicle to overheat.
If your engine overheats during hot weather, there may be a problem with the cooling system that needs attention.
That distinction matters. Do not simply assume, “It’s Florida. Cars get hot.” Your engine is designed to control its operating temperature.
7. Can You Drive After the Engine Cools Down?
Sometimes an engine cools down and appears normal again. That does not necessarily mean the underlying problem disappeared.
A leaking hose, failing cooling fan, low coolant level, bad thermostat, damaged radiator, or another problem may cause the engine to overheat again shortly after you begin driving.
I would be especially cautious if:
- The temperature reached the red zone
- You saw significant steam
- Coolant leaked from the vehicle
- The vehicle lost power
- A warning light remains on
- The engine overheats again after restarting
- You do not know what caused the overheating
In these situations, towing the vehicle to a repair facility is usually a safer decision than hoping it makes the trip.
8. Why Continuing to Drive an Overheated Car Can Be Expensive
Excessive heat can damage important engine components.
The longer an engine operates at an unsafe temperature, the greater the possibility of turning a cooling-system repair into serious engine work.
This is why I tell drivers not to focus only on the cost or inconvenience of a tow.
If the alternative is risking major engine damage, towing can be the less expensive decision.
9. Can Roadside Assistance Fix an Overheated Car?
It depends on why the vehicle overheated.
A minor roadside issue may sometimes be identified after the engine has completely cooled. However, many cooling-system problems require proper diagnosis and repair at a shop.
Therefore, do not expect roadside assistance to permanently repair every overheating problem.
If the vehicle cannot safely continue, the appropriate roadside solution may simply be arranging transportation to a mechanic.
10. What If Your Car Overheats on I-4?
An overheating problem becomes more complicated when it happens on I-4, Florida’s Turnpike, SR 408, SR 417, SR 429, or another high-speed Central Florida road.
Your first priority is getting safely out of the traffic flow.
Once stopped, turn on your hazard lights and avoid standing beside the vehicle near moving traffic.
If you regularly drive I-4, read our guide on what to do when your car breaks down on I-4.
Florida drivers can also check current highway incidents and traffic conditions through Florida 511.
11. What Information Should You Give the Tow Truck Driver?
If overheating leaves you stranded, tell the towing or roadside operator:
- Your exact location
- Your vehicle year, make, model, and color
- Whether the temperature gauge reached the hot or red area
- Whether you saw steam
- Whether coolant or another fluid is leaking
- Whether the engine still starts
- Whether the vehicle rolls, steers, and brakes
- Where you want the vehicle transported
If you are not sure what information matters, our guide to what information to give a tow truck driver provides a complete checklist.
What I Recommend After 30+ Years of Towing Overheated Vehicles
Overheating is one of those problems where drivers often convince themselves to keep going.
“The repair shop is only five miles away.”
“The gauge came back down.”
“Maybe it was just the Florida heat.”
Sometimes you may get lucky. However, you are gambling with an engine that has already warned you something is wrong.
My recommendation is straightforward: if the vehicle has seriously overheated and you do not know why, stop driving it until the cause can be identified.
A cooling-system repair is one problem. Creating major engine damage by continuing to drive is another.
