All this time, you may have been driving your car without any urges to check on the temperature gauge in your dashboard. But as it turns out, checking it regularly will save your engine and your pocket.

Just like people, your car’s temperature also says a lot about its condition and how the entire body is actually doing. Whether the gauge needle points to “hot” or “cold,” it all means that there’s something going on with the engine.

To save your vehicle and your pocket from further damage, it’s time for you to understand what problems your car temperature is telling you.

Too cold? Don’t sweat.

Even though the rainy season feels cold enough to make you think that your engine is freezing, cars nowadays have been smartly built. They are able to adjust their temperatures and keep itself warm when you turn on the engine by compensating with just the right amount of fuel and air.

All you need to do is wait for a few minutes. If the temperature gauge still hasn’t gone up despite the engine having been warmed up, don’t sweat, it’s simply broken. But you should be aware that this condition can also be caused by the stuck-open thermostat.

The thermostat that is stuck open will make a coolant constantly flow into the engine and prevent it from reaching an optimum level of heat. Because if this happens, it will cause problems for the engine to warm up. To fix this, you need to replace the thermostat quickly before another problem arises.

Too hot? Let it sit for awhile.

If you see steam rising from under your hood and the temperature gauge reading high into the red sign when you’re driving, this means that your vehicle is overheating right now.

It’s important not to panic. Turn off the air conditioner and open the windows immediately. Try to pull off the road as fast as possible, then turn off the engine.

Don’t ever try to open the hood immediately unless you want to get burned by steam or the superheated engine coolant. Just let it sit for awhile. You can keep the accessory power on to monitor the gauge and see whether the temperature has dropped into the safety zone.

After some time, you can open the hood and check the water level. If the water level is low, try to add water or some coolant to cool down the engine.

Why your car temperature will go high.

Aside from overheating, there are other few possible reasons that can cause the temperature gauge to suddenly spike high. First, the engine may have lost too much coolant because of a leak or with gradual evaporation that makes the engine lack enough water to cool down.

This problem could also be caused by a broken thermostat, which prevents the valve from opening (stuck-close). As opposed to the stuck-open valve, the stuck-close thermostat holds back the coolant from pouring into the engine. Without the coolant circulating throughout the radiator, the engine soon gets extremely hot.

Another possible reason that could cause the sudden rise in temperature is that the water pump is unable to do its job because the gasket or other parts are broken. When the key of the cooling system fails to run, the temperature gauge will surely show sudden high spikes.

Your vehicle’s temperature is one of the crucial things that make your car function properly. If you don’t start paying more attention to it, you will surely regret it when the engine gets badly damaged by excessive heat.


It’s true that monitoring your car’s temperature gauge could be an inconvenience when you should just be focusing on driving and looking at the road. This is where Carmen gets in the picture.
