Intro to the reasons why your car says overheating but isn’t smoking
There are several potential causes of a car overheating without any smoke. To say that the overheating symbol turning on, at any time, isn’t something you want to see… so I guess without the smoke you’re a bit happier… the little things right? Well, with or without smoke, your car saying it is overheating is never a good sign, right? So let’s take a look at the things that can fix this alarming error with your car. We won’t really go over the causes in depth, because the fixes basically address the reasons why they occur.
Why does your car overheat?
Your car may overheat for several reasons. The most common reason is that the engine is running too hot….. which makes sense. It is too hot… because the engine hasn’t cooled. WOW that was super helpful. But when it comes down to the causes of the overheating, it can be broken down to a couple of things, including a coolant leak, a faulty thermostat, or a clogged radiator. If your car overheats, you should pull over and turn off the engine as soon as possible.
Check the radiator and water pump
If your car is overheating, but there’s no smoke coming from the engine, there are a few things you can check before calling a tow truck. First, make sure the radiator and water pump are full. If they’re not, add coolant and water until they’re full. There is a pretty decent chance that by adding a liquid to cool your engine, you will be able to get to a service station. Once there, you’ll be able to check the radiator hose for any leaks. If it’s leaking, you’ll need to replace it ( not really any way around that).
Either way you don’t want to be stuck outside on a hot day, which is the opposite of if your car won’t turn over on a cold day. ( Another post we wrote to keep you safe and comfortable on a trip )
Check the thermostat
If your car overheats, it’s important to check the thermostat. A thermostat that is stuck closed can cause your car to overheat. A stuck open thermostat can prevent your car from getting hot enough to operate properly. At its most basic level, the thermostat tells the car what its own temperature is; if it says it is too cold, it won’t heat it up, and the reverse is true. So if it is stuck saying that it isn’t hot enough, it will continue to heat up… then making it overheat. This is actually a pretty easy fix as well and is one thing that this usually checked when you take the car in for services with your routine maintenance.
Check the engine coolant level
If your car is overheating, but there’s no smoke, and the first two tips didn’t work, then the next thing you should check is the engine coolant level. If it’s low, add coolant until it reaches the full line. You should also check for leaks in the cooling system. This is similar to the first one, but it is more specific to the level itself.
Conclusion: possible causes and solutions
While an overheating car is a cause for concern, it’s important to remember that not all causes of overheating are serious. In many cases, the problem can be easily fixed at home with a few simple steps.
One possible cause of an overheating car is a low coolant level. If the coolant level is low, the engine will not be able to cool itself properly and will eventually overheat. The solution to this problem is simply to add more coolant to the system.
Another possible cause of an overheating car is a faulty radiator fan. The radiator fan helps to keep the engine cool by circulating air around it. If the fan is not working properly, the engine will eventually overheat. The solution to this problem is to replace the faulty fan with a new one.
