The right coolant is indispensable for maintaining optimal engine temperature

Its main job is to absorb and carry away the heat generated by the engine during operation

Failure to maintain adequate cooling may result in warped cylinder heads, cracked blocks, or catastrophic engine seizure

The fluid travels through internal passages in the block and heads, absorbing heat before being sent to the radiator for thermal dissipation

Modern coolants are not just water

They consist of water, corrosion inhibitors, lubricants, and antifreeze agents designed for peak performance

The antifreeze component prevents the liquid from freezing in cold weather and raises its boiling point so it can handle high engine temperatures

These chemical additives prevent electrolytic corrosion, seal degradation, and coolant system scaling to maintain long-term efficiency

The chemical composition of coolant deteriorates after prolonged use

Corrosion byproducts, rust particles, and debris accumulate as the inhibitor package wears out

Routine coolant inspections and replacements are non-negotiable for engine longevity

Service intervals range from 30k to 150k miles depending on coolant type, vehicle make, and usage patterns

Early detection of murky, oily, or rusty coolant can avert costly radiator or اتوسرویس داوود water pump failures

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

If you notice boiling fluid, hissing sounds, or the temperature needle entering the red zone, stop immediately

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

Always let the engine cool before checking or adding coolant

Incorrect coolant formulations can trigger chemical incompatibility and system failure

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

Mixing incompatible coolants can reduce their effectiveness or cause chemical reactions that clog the cooling system

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
