Coolant Temperature Warning! What’s Going On and What to Do

What Problems Could Your Coolant Temperature Warning Light Indicate. And What Should You Do About It?

Imagine this: your headed home from a day at Old Town in Lewisville when suddenly your coolant temperature warning light beams from your dashboard. And you wonder what could be going on! Because, you know that your vehicle’s coolant temperature warning light is one of the most important indicators on your dashboard. And ignoring it can lead to costly repairs or even engine failure. Because this light (which typically resembles a thermometer icon) signals that your engine is at risk of overheating.

So, in this blog, the experts at Meineke in Lewisville offer this breakdown of the problems your coolant temperature warning light could signal, and the steps you should take to address it.

1. Low Coolant Levels

The most common reason for a coolant temperature warning light is low coolant levels. Because, your car’s engine relies on coolant (a mix of antifreeze and water) to regulate temperature. But, over time, coolant levels can decrease due to natural evaporation or a leak in the system.

What to Do:

- Check your coolant reservoir to see if the fluid level is below the “minimum” line. And if it’s low, top it off with the appropriate type of coolant for your vehicle (refer to your owner’s manual). However, if you find yourself refilling coolant frequently, it’s a sign of a leak. And this should be inspected by the professionals at Meineke on West Main Street in Lewisville.

2. Coolant Leaks

A coolant leak can occur due to worn-out hoses, a cracked radiator, or even a leaky water pump. And when coolant leaks out of the system, the engine loses its ability to stay cool and may overheat, triggering the warning light.

What to Do:

- If you notice coolant pooling under your vehicle or the smell of antifreeze, you likely have a leak. So, until you can have the leak repaired, avoid driving as much as possible to prevent overheating. And have the ASE certified mechanics at Meineke in Lewisville inspect the system to locate and fix the leak.

3. Faulty Thermostat

The thermostat regulates the flow of coolant between the engine and radiator. So, if it’s stuck closed, coolant won’t circulate properly, causing the engine temperature to rise. And this can trigger the coolant temperature warning light.

What to Do:

- If your engine heats up rapidly or fluctuates in temperature, the thermostat may be the culprit. So call the auto care experts at Meineke in Lewisville to quickly diagnose and replace a faulty thermostat.

4. Radiator or Fan Malfunction

The radiator and cooling fan play key roles in removing heat from the engine. So, if the radiator is clogged or if the fan fails, coolant won’t cool down efficiently. And this can lead to an overheated engine.

What to Do

- Check if your radiator appears dirty or clogged and, if possible, clean it carefully. Also, listen for the fan’s operation when the engine is hot. Because, if it doesn’t engage, it could be a sign of a fan or sensor issue. Also, the professional mechanics at Meineke in Lewisville can further inspect the radiator and fan system to identify any faults.

5. Water Pump Issues

The water pump keeps coolant circulating through the engine and radiator. So, if it malfunctions, the flow of coolant stops. And this causes the engine temperature to spike, triggering the warning light.

What to Do

- A failing water pump is serious and should be addressed immediately. So, look for signs of a bad water pump including a whining noise from the engine or visible coolant leaks near the front. And don’t continue driving if you suspect a water pump problem—have it towed to Meineke on West Main Street in Lewisville.

6. Electrical Sensor Malfunction

In some cases, the coolant temperature warning light may illuminate due to a faulty sensor. And the temperature sensor monitors engine heat and signals the light if it detects overheating.

What to Do

- If you’ve checked coolant levels and other obvious issues, the light may be due to a malfunctioning sensor. So have a the mechanics at Meineke in Lewisville test the sensor and replace it if necessary.
