What Are The Common Radiator & Cooling System Issues?


Pull your car off the road before your engine is cooked and destroyed if the temperature warning light glows bright red on the dashboard, or steam pours under the hood, or the temperature gauge needle touches the high mark.

There is definitely something wrong with the car's cooling system, and you want to do anything to keep it from overheating, or things will get difficult. Radiator and cooling system issues are common problems of auto repair in New Hope.

What To Do If You Notice Any Signs Of Overheating?

It is a serious issue if there is any sign that your engine is overheating. The right way forward is to stop your engine to prevent any further complications.

And if you do not shut down the engine at that moment and continue to drive your car, it will lead to twisted cylinder heads and harm the radiator or even the internal engine parts like pistons, valves, and camshafts.

Even when you allow your engine to cool down for more than an hour and top off the radiator with water and antifreeze in a 1:1 ratio, the problem is far from over. 

In a few cases, the damages are irreversible, and you might have to think about engine replacement. It is an expensive undertaking, and it may feel best to purchase a new then get an engine replacement.

7 Top Reasons Causing An Engine To Overheat

i) Low Coolant Level
It is because of extremely low coolant level due to long-term neglect or coolant leak in the radiator or radiator hoses. The coolant flows within the engine block and the leak from water heater hoses or water pump or even in the block. The old coolant loses its corrosion repressing properties, allows rust formation, and eventually causes damage.

ii) Stuck Thermostat
A thermostat is a helping hand for the coolant to flow might get stuck in a closed spot or clog develops. The clogs form due to the debris in the cooling system.

iii) Radiator Cap Goes Bad
A bad radiator cap can no longer sustain proper cooling system pressure. Coolant can boil over if the pressure isn’t maintained. The engine operates at around 200 to 220 Fahrenheit.

iv) Head Gasket Seal
The head gasket’s functionality is to seal the gap between the engine block and cylinder head. If it fails to do so, the coolant leaks in the combustion chamber. You can see the steam coming out from the exhaust system. 

v) Engine Cooling Fan
The radiator’s cooling fins can get clogged by debris, or the engine cooling fan stops operating, and it will result in the rise of the coolant’s temperature.

vi) Water Pump Stops
If the water pump stops operating or the driving belt is slipping, or it breaks can cause an insufficient amount of coolant to be pumped. The lack of proper coolant can also cause the engine to overheat.

vii) Towing Exceeds Capacity
If you tow a 5000-pound trailer with a vehicle tow capacity of only 2000 pounds, it is bound to have an adverse effect on the cooling capacity. By doing so, you can also strain your transmission.

What Can You Do To Avoid Engine Overheating

It helps if you regularly check the coolant level in the engine’s overflow tank to avoid such instances. 

If you have to top off the coolant more frequently, it is a sign of leaking. You should look into it before it becomes a significant issue. It might cause more critical damage by overheating your cooling system. 

Another step that you can take is to get your cooling tested and have the entire system inspected by a professional mechanic every year to ensure if everything is working fine or not. This will help prevent future cooling system issues.

How To Detect If Your Radiator Is Leaking? 

The clear indication is if the temperature warning light is on or the temperature gauge on the dashboard is high, there is an issue with the cooling system that might have caused the leakage. However, it can be due to the radiator or any other part. There are many other auto repair issues and their causes that you know about to get a timely repair.

i) Detect What’s Leaking
The first step is to see if it is the cooling that’s leaking or any other fluid. Poland is also known as antifreeze.

You can check the coolant level in your overflow tank. If it is low or empty, you must check the radiator’s coolant level. But always check it once the engine cools down.

If the coolant level is low in the car’s cooling system, it can cause the engine to overheat, or your cabin’s heater will start blowing cold air.

ii) Losing Coolant
If you are certain that you are losing coolant, the radiator is the best place to check for leaks. 

You can easily spot some of the radiator leaks, like a growing puddle under the radiator. But other signs are not that easily detectable. Always make sure that you're checking the radiator thoroughly from every angle and not just from the above. Particularly pay attention to the bottom and seams.

Another factor that causes the radiator to leak the coolant is road debris or rust in the radiator. Even if your vehicle’s radiator is of aluminum material, it technically may not rust, but it will corrode and develop pinhole leaks. 

iii) Different Colors
Antifreeze is available in many different colors like pinkish red, green and yellow. 

It feels like slimy water and usually has a sweet smell. 

If you cannot see coolant seeping or drip, you must look for cracks, rust, or discoloration on the radiator. These are one of the indications that there is a leakage.

iv) Other Possibilities
If the radiator is working fine without any issues, there are many other possibilities of leakage. These possibilities can range from hoses between the radiator and engine, water pump, thermostat, heater core, radiator cap, engine block, reservoir tank, etc.

Another possibility is a blown gasket between the engine block and cylinder head can cause the coolant to leak into combustion chambers. You must contact a professional auto repair shop to help you address this problem.

If you are unable to spot the leak that means you should get it checked at an auto repair shop. Coolant can easily leak under pressure from a running car, and that too in steam form, not leaving traces. If the culprit doesn’t get caught on time, it can cause significant engine damage. So, finding the leak spot is essential. 

The radiator and coolant system issues can cause significant damage to the engine, making its resolution vital. However, consult a professional ]]>auto repair in New Hope]]> like A&G Customs.
