This is what happens when your heater core is clogged. Reason#5 – Heater Core Is PluggedĮarlier, we mentioned that if your car is overheating with full coolant, it’s likely due to its inability to flow through the cooling system. Obviously, if this component isn’t working as it should, it can cause your engine to overheat. If it is stuck for some reason, it won’t be able to do so correctly. The thermostat is in charge of regulating how much coolant flows through the cooling system. Sadly, though, if it’s damaged, replacement is likely your only option. Thankfully, it’s pretty easy to visually inspect the radiator due to its location near the front of the vehicle. If it is damaged, or if something has become lodged in it, the coolant might not be able to flow through. Reason#3 – Radiator Has A BlockageĪs coolant flows through the radiator, it absorbs heat and disperses it. As you might have guessed, if your water pump is failing, your engine won’t receive enough coolant, which can cause it to overheat. The purpose of the water pump is to push coolant from the radiator throughout the rest of the cooling system. This can stem from several things, including a faulty water pump, a radiator blockage, a stuck thermostat, or a plugged heater core. Instead, it may be that it’s having trouble circulating correctly. However, if your car is overheating but the coolant is full, it is probably not a leak. Thankfully, if you’re running low, you may just need to add more. The purpose of coolant is pretty much described in its name – it keeps your car cool so that it doesn’t overheat. Is Your Car Overheating? Here Are The Most Common Reasons Reason#1 – Engine Coolant Is Low Let’s look at the most common causes of a car overheating. Now that you better understand the signs that suggest your engine is overheating. ![]() This will manifest as reduced power, meaning your car will struggle to accelerate when you step on the gas.īe sure to watch for any of the previously mentioned symptoms to be sure. When an engine overheats, it expands, slowing down its ability to function. Symptom #6 – The Engine Has Reduced Power If it happens repeatedly, there’s likely something that needs your attention. However, if you can’t hold your hand on the hood for 10-seconds without it hurting, then it’s reached a point where it’s excessive.īe sure to turn the car off when it’s safe to give it a chance to cool down. You should always feel some heat coming from your hood, especially if the engine has been running for a while. This usually means that the coolant inside your engine has passed the boiling point, manifesting as steam. ![]() If steam starts billowing out from under the hood, be sure to pull over as soon as it’s safe. Steam coming out of something is usually a clear indicator that it’s hot, and thankfully, the same goes for your engine. Symptom #4 – Steam Is Coming From Under The Hood If the coolant reservoir is full, but the car is still overheating, there’s likely something more severe going on. In this case, adding more coolant might be a temporary solution, but eventually, you’ll need to track down the leak. If there’s a leak, it may end up pooling under your car, meaning your engine won’t have enough, which can lead to overheating. Symptom #3 – You Notice A Puddle Of Coolant On The GroundĬoolant is designed to keep your vehicle within a safe temperature range. Hot oil loses its thickness and can’t lubricate well anymore, which leads to the ticking sound. If you hear a “tick” noise, it means your engine oil is too hot. When the thermostat opens, and the cold coolant mixes with the hot, it may cause a thumping sound. If your engine gets too hot, though, the coolant that’s already inside can start to boil. Because of this, your thermostat is built to block the flow of coolant until the engine can warm up. Your engine needs to reach a specific operating temperature to function correctly. Symptom #2 – Your Engine Is Making A Ticking Or Thumping Sound ![]() If it starts creeping into the red, there’s a good chance something needs your attention. If you don’t have a specific temperature indicator, you should at least have a gauge. If this is the first sign you notice that your car is overheating, then count yourself lucky because it’s also a prime chance to handle it before it causes costly damage. The great thing about an engine that’s getting too hot is that it will likely illuminate the temperature indicator. What Are The Symptoms Of An Overheating Car? Symptom #1 – The Temperature Light Appears ![]()
