Toyota Genuine Super Long Life Coolant 4L
Engine coolant is a liquid mixture of water and antifreeze located in your vehicle's radiator. It prevents your engine from overheating in hot weather and freezing in extreme cold weather, conditions where things can go very wrong for an engine.
Key features of an effective radiator coolant are:
- Effective heat transfer.
- Prevention of cooling system corrosion.
- Effective boiling point.
- Chemical stability.
- Safe for use as directed by manufacturer.
How often should you fill coolant?
Coolant should be topped up whenever the level drops below the guide marks. When it comes to draining and changing the coolant altogether, manufacturers guidance also varies although this can be after a minimum of 30,000 miles depending on how old your car is.
