How long can coolant last

Yes, engine coolant does go bad. Older fluid may cause acid buildup, may become contaminated by rust or scaling, and may have reduced resistance to boiling and freezing. In a coolant flush , a chemical is first added to the cooling system that removes debris and buildup from the system. A machine is then used to remove the old fluid and add new fluid. The machine pushes the fluid through the system at the same speed it would travel were the engine actually running.

A coolant drain and fill , or standard coolant service, is just that. The fluid is drained from the vehicle using gravity instead of a machine and the new fluid is mixed and refilled by hand.

The coolant does not just keep the engine cool, it also prevents corrosion and scale build-up. Traffic signs come in all shapes, sizes and colours. While we may be inclined to believe that road signs are synonymous with red, yellow and green, that is just the tip of the iceberg.

The stop, watch When the word coolant is used in can mean a couple of things. Coolant made up of antifreeze and water out of your household tap, solution, would last for around 3 years.

Coolant made up of antifreeze and distilled de-ionised water, solution, should last for around 5 years. Because of the nonsense surrounding 'coolants' always adhere to the instructions on the supply container. If you live in an area of the world subjected to very low temperatures you could look at a coolant change on the outset of winter as a sort of insurance.

Just went to top off my cooling system and noticed the Anti-Freeze I went to use from the original capped container was black. I've had it for well over 5 years, so apparently it does go bad eventually.
