The cooling system works by constantly passing coolant through channels in the engine block. Coolant, driven by a water pump, is pushed through the cylinder block. As the solution passes through these channels, it absorbs heat from the engine.
The major components of the cooling system are the water pump, freeze plugs, the thermostat, the radiator, cooling fans, the heater core, the pressure cap, the overflow tank and the hoses.
How does coolant flow in a car?
The engine contains internal hollow structures called water jackets. The coolant flows inside the engine through these, absorbing the engine’s heat. It then travels through hoses to the radiator, where it cools down. From there, it’s back into the engine, where it displaces hot coolant to repeat the process.
The four common problems with cooling systems we will cover on our blog, include:
Water pump failure.
Leaky radiator hoses.
Radiator leaks.
Thermostat failures.

Discolored and thicker coolant. You know your coolant’s original color, don’t you?
Damaged water pump.
Excessively high gauge temperature readings.
Blocked, bent, or damaged radiator fins.
What are the signs of a failing cooling system?
Here’s a look at six signs of cooling system trouble.
Smoking. If smoke starts emerging from under your hood, then it’ll be best to pull off the road, at which point you’ll likely want to add coolant/water.
High Reading on Temp Gauge.
Decreasing Gas Mileage.
Low Coolant.
White Exhaust Smoke.
External Coolant Leak.
What is the major cause of cooling system failure?
This issue could be caused by a faulty thermostat, an obstruction in the radiator, a fan or the water pump has malfunctioned preventing the coolant from flowing and dissipating heat as intended.
What are the common troubles of cooling system and their remedies?
Frozen coolant.
Loss of liquids coolant due to leaks. The liquid coolant may leak from the cooling system.
Overheating. Overheating is one of the main cooling system problems.
Overcooling.
Incorrect Temperature Gauge Reading.
Noise.
Frozen Coolant.

How do I fix my cooling system?
Can I use water instead of coolant?
Technically speaking yes you can use plain water in your cooling system but it isn’t recommended as a long term solution and certainly not in extreme weather conditions. The problem with using water in your cooling system is that water freezes at 0°C.
Chances are you have either a radiator cap leak, internal coolant leak or an external coolant leak. The longer you wait the higher the coolant leak repair cost will be.
How do you check coolant flow?
Start your car’s engine and allow it to idle. Look through the radiator filler neck to see if the coolant flows. At this time, it should not be flowing as your car has not reached the operating temperature to cause the thermostat to open. If you find the coolant is flowing, it means the thermostat valve is open.

How do you know if your water pump is failing?
Five Signs Your Water Pump Is Failing
Overheating. A dead or dying water pump cannot circulate coolant through your vehicle’s engine and, as such, the engine will overheat.
Coolant Leaks. Coolant leaks from the water pump are common and a clear sign that it’s time to replace the pump.
Corroded Water Pump.
Whining Noises.
How do I know if my water pump is bad?
6 signs your water pump is failing
Coolant Leak. The water pump has several gaskets that can be damaged or worn out over time.
Engine Overheating.
High Pitched, Harmonic Whining Noises.
Water Pump Rust and Corrosion.
Steam comes out from under your hood.
Holes or leakage system on the dry side of the water pump.
What sound does a failing water pump make?
Whining or Groaning Noise
A whining or groaning noise usually means that either a drive belt is loose, or the water pump pulley is bad. It may surprise your customer that a pulley could fail, but it does occasionally happen.
Too little or no coolant. Driving without proper levels of coolant/antifreeze may cause a coolant system failure.
Cooling system leaks.
A broken water pump.
Radiator issues.
Oil too low.
Thermostat failure.
Issues with the belts and hoses.
Heater core is plugged up.
What causes water pump failure in car’s?
Contaminated coolant, non-compatible coolant, or mixing coolants of different chemistries leads to premature water pump failure. Harmful contamination is common in systems that are not properly maintained.
Can you drive a car with a broken water pump?
It is possible to drive your vehicle without a water pump, but not good to. Some people in the racing circuit or who drive racing vehicles purposefully remove their water pumps to obtain more horsepower to their engine. If you are driving a vehicle for everyday use though, a water pump is a must.
