5 Serious Consequences When You Don't Change Coolant Regularly?

Coolant - The Silent "Lifeblood" Of The Engine

When it comes to car maintenance, many people often think only of changing the oil, checking the tires or the battery. However, there is an equally important type of solution that is often overlooked, which iscoolant. Coolant is not simply "water", it is a complex chemical mixture whose job is to absorb the huge amount of heat from the engine and release it into the environment, keeping the "heart" of the car always operating at the ideal temperature.

Ignoring regular coolant changes is a mistake that can lead to extremely serious and costly damage. Let's find out with Gartz.5 unforeseen consequencesthat you will face.

1. Engine Overheating (Cooling Water) - "Nightmare" on the Road

This is the most immediate and obvious consequence. Over time, the anti-boil additives in the coolant will degrade and lose their effectiveness. At that time, the solution will easily boil at a lower temperature, especially when the car is moving slowly in the city or climbing a hill.

Consequence:An overheating engine can cause the radiator to boil, steam to billow from the hood, and in the worst case, it can warp or crack engine parts, forcing you to stop in the middle of the road and face major towing and repair costs.

2. System Corrosion and Water Tank Clogging

Old coolant not only loses its ability to cool but also loses its anti-corrosion additives. At this point, the solution will become a corrosive agent for metal parts inside the system such as the radiator, water pump, and aluminum and cast iron pipes.

Consequence:The corrosion process creates rust particles. These particles circulate through the system and clog tiny pipes inside the radiator, severely reducing the ability to dissipate heat and creating localized "hot spots" in the engine.

3. Water Pump Failure - The Heart of the Cooling System "Stops Beating"

The water pump is responsible for circulating coolant throughout the engine. Old coolant, filled with dirt and rust, will act like sandpaper, wearing away at the water pump's impeller and seals.

Consequence:A broken water pump will not be able to push the water away, causing the engine to heat up extremely quickly after only a few minutes of operation. The cost of replacing the water pump is not cheap, especially for new cars with complex structures.

4. Blown Engine Gasket - Most Serious Damage

This is one of the most serious and costly failures caused by overheating. The head gasket is the seal between the engine block and the cylinder head. When the engine overheats, the pressure in the system increases, which can destroy the gasket.

Consequence:Coolant will leak into the combustion chamber (causing white smoke from the exhaust) or mix with the engine oil (causing the oil to have a coffee-milk color). Repairing it requires removing the entire cylinder head, which is very time-consuming and expensive.

5. Reduced Lifespan of Plastic and Rubber Parts

Old coolant is no longer able to protect non-metallic parts. Rubber hoses will become brittle and prone to cracking, while plastic parts may corrode, causing coolant to leak out.

Consequence:Even a small crack in a pipe can cause the system to lose all its coolant in a short period of time, leading to serious consequences as mentioned above.

Solution From Expert Gartz: Prevention Is Better Than Cure

Don't wait until your car breaks down to take action. Changing your coolant at the manufacturer's recommended intervals (usually every 40,000 - 60,000 km or 2-3 years) is a small investment that pays big dividends.
