There are a few different reasons that your coolant might not be building pressure. You might have a busted radiator cap, or you might have a leak or busted water pump. Either way, low coolant pressure is going to lead to an overheating engine.
Why won't coolant flow through my car?
Your vehicle’s coolant flows through the radiator’s fins to cool down, and if those fins are clogged or blocked, you won’t get enough coolant flow through your engine to effectively cool it down. Another problem is if debris blocks the front of your radiator.
What to check for when an engine is overheating?
When troubleshooting an overheating engine, the simplest thing to check is your fluid levels.
What happens if your car thermostat is cold?
If it is still cold when the car starts to overheat, you probably have an issue with the thermostat. Remember that if you have a broken electric thermostat, you will usually have a check engine light – but that’s not always the case. If your thermostat checks out, take a look at your fan.
What happens after a coolant flush?
After a coolant flush, you need to make sure that you get all of the air pockets out of the cooling system. Air pockets will cause your entire system to jam up, and you won’t get any coolant flow.
Why does my radiator keep getting hot?
Sometimes a radiator might have a broken fan which prevents the hot air from escaping. Other times, there are leaks or clogs in the radiator or even a faulty radiator cap. All this leads to an overheated engine.
Why is my engine overheating but no coolant leak?

Luckily, there are a number of warning signs ...
Why does my engine overheat?
Your engine can overheat for a number of reasons. Some of the most common causes of this are mechanical failures such as broken fans or blown head gaskets.
Why does my car have a puddle of coolant?
It also could indicate that your engine has overheated and boiled the coolant within the radiator, causing the overflow tank to release excess liquid to relieve the high pressure created. In either situation, your car’s cooling system no longer has the correct amount of coolant flowing through the engine, so it will be prone to overheating.
What happens when coolant gets stuck in the radiator?
If this valve gets stuck, the trapped coolant in the engine block will become superheated. When cold coolant comes into contact with the superheated coolant, you will hear a loud thumping noise coming from the engine area. Getting the thermostat replaced usually fixes this issue.
How to tell if your engine is overheating?
Steam billowing out from underneath your hood is a sure sign that your engine is overheating. As soon as you notice, pull over and turn off the engine. Coolant that has reached its boiling point will convert into steam and build pressure within the cooling system. When it escapes from your car’s radiator cap or coolant reservoir, you will see it coming out from the front and sides of the hood.
What does it mean when your engine light flashes?
If the light flashes on or the gauge reads near maximum, it means there is excessive heat generating in your engine. However, this warning light cannot always be trusted to alert you of an overheating engine.
What happens when oil is overheated?
When engine oil is overheated, it loses its lubricating properties and behaves more like water than oil. At high temperatures, if the mechanical parts of your engine are clacking against each other audibly you can expect them to undergo wear and tear at a much higher rate than usual.

Why is my car running out of coolant?
Ran Out Of Coolant: One of the very basic reasons is the cooling system failure. Engine coolant removes any excess heat from a car’s engine maintaining a suitable temperature for it. There is a temperature gauge that indicates the temperature of a car’s coolant. It monitors the hot or coldness of the coolant and shows it on the dial.

Why does my engine keep cool at low speeds?
Your engine may be able to stay cool at low speeds because it's not working that hard, and therefore not creating as much heat. When you hit highway speeds, however, your engine needs a lot of coolant flowing through to keep it cool. If the thermostat doesn't open, there isn't enough flow to keep things cool.
How to test if a radiator fan is bad?
To test this, find your radiator fan switch and disconnect the wiring harness. Get a jumper wire and insert it into both contacts, your fan should come on. Another way to test the fan is to turn on the air conditioning. The cooling fan is activated in most—but not all—cars when you turn the AC to either a medium or high speed.

Why does my car overheat?
By a large margin, the most common cause for engine overheating is simply a low coolant level. Your engine's cooling system relies on coolant to circulate and remove heat from the engine. If you don't have enough coolant in there to do the job, heat will build up and your engine will overheat.
How to tell if your car fan is running?
You can test this by letting your car idle long enough for the engine to heat up. If you have an overheating problem in traffic, keep an eye on your temperature gauge. When it starts creeping into the danger zone, look under the hood to see if your electric fan is running. If it's not, you'll need to figure out why. Typically, it comes down to one of two problems.

Is engine coolant straight forward?
Most engine coolant systems are fairly straight forward and simple to pin point the issue should not be a daunting task.
Coolant Leak
Clogged Hoses
- If your engine is overheating but there is no coolant leak, then you might have a clogged coolant hose. This might happen if sediment or dirt from the road inadvertently got into the hose. This will block the coolant fluid from being able to flow through the system properly.
Bad Water Pump
- The water pump is the component which propels the coolant fluid so that it can flow in the cooling system. If the water pump is damaged or worn out, your engine will overheat from it. Check the impeller vanes or bump shaft because these are commonly the reasons for the water pump going bad. There may even be leaks too.
Faulty Radiator
- The radiator is what transfers heat out of the hot coolant so that it can cycle back into the engine and cool it down again. If you have a bad radiator, the coolant liquid is going to stay hot. This means the engine is going to stay hot as well. Sometimes a radiator might have a broken fan which prevents the hot air from escaping. Other times, ther...
Wrong Coolant
- You might not see any leaks or faulty components at all, but still notice your engine overheating. If you put new coolant fluid in your vehicle recently, then perhaps you used the wrong cooling fluid. The best thing you can do is flush your entire cooling system and then add the right cooling fluid back into the system. Related: Different Types of Coolant (and Their Colors)
Low Engine Oil
- As stated earlier, motor not only acts as a lubricant between the moving components inside an engine, it acts keeps internal temperatures at bay. If your engine has too low of an amount of oil(or old oil that’s deteriorated enough), excess friction will be the result which drastically raises the engine temperature. This can ultimately result in overheating and internal engine damage.
