The right coolant is indispensable for maintaining optimal engine temperature

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 head gasket blowout

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

Today’s engine coolants are far more complex than plain H₂O

These fluids are engineered blends of water, ethylene or propylene glycol, and a cocktail of protective chemicals

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

The chemical composition of coolant deteriorates after prolonged use

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

This is why regular coolant checks and changes are important

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

Monitoring fluid level, color, and clarity helps catch issues before they escalate

Even minor coolant loss can trigger rapid temperature spikes during routine operation

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

Never open the coolant reservoir when the engine is hot, as pressure can cause hot fluid to spray out

Always let the engine cool before checking or adding coolant

Using the wrong type of coolant can also damage the engine

Each manufacturer specifies a coolant type—OAT, HOAT, or IAT—based on metallurgy and design

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

A well maintained cooling system extends engine life, improves fuel efficiency, اتوسرویس داوود and prevents expensive repairs

Consistent coolant checks are a small investment that pays off in reliability, safety, and savings
