Does antifreeze make engine cooler?

When traditional water-based antifreeze reaches its boiling point, it becomes less efficient at cooling the engine. At high tempertatures, liquid antifreeze is not cool enough to condense the vapor, and the vapor forms a pocket that keeps the coolant away from the hot metal of the engine.

Can I use distilled water as coolant?

Many people have “heard” that distilled water is the best water to use in a cooling system. This is wrong! While it is certainly true that distilled water’s purity prevents electrolysis and scale/deposit formation, it unfortunately comes with a potentially very damaging side effect.

How long until engine cools down?

It typically takes a solid 30 minutes for an engine to cool down enough for it to be safe to handle. If you’d rather let a professional handle the problem, it’s time to call for a tow truck. Once the engine has cooled, check the coolant tank. It’s usually a translucent plastic tank near the radiator.
