Warning Signs of a Cooling System Problem

As soon as you start your car, your engine temperature starts climbing. If any aspect of your cooling system is malfunctioning, the ascending temperature may cause overheating, which could lead to major problems, including a cracked engine block. But so long as your cooling system is working properly, you'll have the measures in place to operate at a safe temperature. Here are six symptoms of cooling system trouble.


A classic sign of overheating is that smoke emerges from under the hood. In such a scenario, you may need to add coolant/water, which should only be done after the engine has sufficiently cooled down.

Temp Gauge in the Red Zone

If the temperature gauge on your dashboard climbs into the red zone, then it'll be best to safely pull over. At the point, it's worth calling up a mechanic and describing the situation so you can get advice on whether you should drive your vehicle any further down the road.

Worsening Gas Mileage

Your vehicle gets optimal gas mileage when its engine remains within a healthy temperature range. When the engine is running hot, you may notice a drop in MPGs.

External Coolant Leak

It's a good idea to occasionally check the ground where your car is often parked and see if there are any signs of automotive fluid leaks. Coolant can often be identified by its bright color. This fluid is commonly green, though the coolant in your vehicle might be another color, such as pink or yellow.

Low Coolant Level

If your coolant level has started dropping, you'll want to have a mechanic take a look so the underlying issue can be diagnosed. With this symptom, you could have an internal coolant leak.

White Exhaust Smoke

White exhaust smoke suggests that there's an internal coolant leak. This occurs when coolant burns up in the combustion chamber. A cracked cylinder head could be at the heart of this problem.
