Proper engine cooling depends heavily on the performance of coolant

Coolant’s primary purpose is to regulate engine temperature by absorbing and dissipating generated heat

Overheating due to insufficient coolant can cause irreversible damage including piston seizure and اتوسرویس داوود head gasket blowout

As it moves through the engine’s cooling passages, coolant collects waste heat and delivers it to the radiator for cooling and reuse

Coolant is not simply distilled water—it’s a precision-engineered fluid

They are specially formulated mixtures that include water, antifreeze, and additives

Antifreeze lowers the freezing point and elevates the boiling point, allowing the fluid to function reliably in extreme climates

The additives protect the metal parts inside the engine from corrosion and rust, and they also help lubricate the water pump and prevent scale buildup

Coolant degrades with age, losing its protective properties

Over time, sludge, scale, and metallic residues form, reducing heat transfer and clogging passages

This is why regular coolant checks and changes are important

Most manufacturers recommend replacing coolant every 30,000 to 60,000 miles, but this can vary depending on the vehicle and driving conditions

Checking the coolant level regularly and looking for signs of leaks or discoloration can prevent bigger problems down the road

Insufficient fluid volume leads to hot spots that can damage internal components within minutes

An overheating indicator, elevated temperature gauge, or visible vapor are unmistakable red flags

Opening a pressurized coolant system while hot risks severe burns from scalding liquid

Always let the engine cool before checking or adding coolant

Using the wrong type of coolant can also damage the engine

Using generic or universal coolant may void your warranty or compromise system integrity

Combining different chemistries can create gels, precipitates, or sludge that obstruct flow

Maintaining proper coolant levels and condition is one of the simplest and most cost effective ways to protect your engine

Consistent coolant maintenance directly contributes to longer engine durability and better mileage

Regular maintenance may seem like a small task, but it can save you from major breakdowns and costly replacements in the long run
