Coolant Types Explained: Which Does Your Car Need?
Using the wrong coolant can damage your engine. A Cranbourne West specialist explains the types.
Why coolant type matters
Coolants come in different chemistries (e.g. older IAT, and newer OAT/HOAT types), usually colour-coded — but colour alone isn’t reliable. European cars specify a particular coolant, and mixing incompatible types can cause gelling, corrosion and blocked passages.
The right coolant protects the radiator, water pump and engine for years; the wrong one can cause expensive damage.
Getting it right
Always use the coolant type your car specifies, pre-mixed to the correct concentration — don’t just top up with whatever’s on the shelf. If the coolant type is unknown or has been mixed, a flush and refill with the correct type is the safe move.
We use the correct coolant for your exact car and flush/refill properly when needed.
Not sure which is right for your car?
Every car and situation is different — the best choice depends on your exact vehicle, how you use it and its condition. We give you straight, no-pressure advice based on what’s actually best for you, not what makes us the most.
