Quick quiz: when was your coolant last changed? π§π₯
Not sure? Youβre not alone. With colder nights coming, itβs worth knowing.
Coolant doesnβt just stop overheating. It also:
βοΈ Protects against freezing
π‘οΈ Helps fight corrosion inside the engine
π‘οΈ Keeps your engine in its happy zone
How often should you change it? Check your ownerβs manual. It varies a lot by vehicle, so thereβs no one magic number.
Bought a used car with no records? Thatβs a great reason to have it looked at.
π¨ Coolant level keeps dropping? Thatβs usually a leak, not βnormal.β
β οΈ Only check the reservoir when the engine is completely cool. Never open a hot radiator cap.
Drop a 1οΈβ£ if you know your last coolant service, or a 2οΈβ£ if you have no idea. π
