Can You Use Water Instead Of Engine Coolant

So use it only in unavoidable situations.

Can you use water instead of engine coolant. One thing straight always mix water and coolant in equal consistencies. Yes you can put water in your coolant for your vehicle only in non winter weather states. The coolant has the important task of preventing corrosion in the engine block but you should not use it excessively. We want to use distilled water and not ordinary tap water that has minerals to prevent lime scales from forming inside the cooling system.

A coolant water solution increases the boiling point from 212 degrees to about 265 degrees compared to when only water is used. However this should only be done in an extenuating circumstance and never in a cold climate location. Hy per lube super coolant contains molybdate a form of the semi precious metal molybdenum which is proven to be extremely effective in preventing galvanic action and electrolysis regardless of what type of water is used. This could also cause expensive engine damage.

However doing so is not recommended since water won t work well beyond its freezing and boiling points. The minerals also increase the risk of corrosion in the engine parts. Never use it if the outside temperature is really low. The high boiling point of antifreeze plus its anti corrosion additives are a good complement to water s natural cooling capabilities as long as its distilled water.

Aside from using antifreeze coolant there are also other cooling system additives that contain rust inhibitors and also increase the heat transfer properties of the water in your system. A surprising number of people imagine that using pure water instead of a water coolant mixture in a car radiator is fine if you live in a warm climate. On the contrary this does not mean that you can t use water at all. The engine will tend to overheat with it so don t stress the engine too much.

If the engine overheats stop and wait for it to cool off. However if you use hy per lube super coolant you don t need to use softened water. Yes you could use water as a coolant in an emergency. Drive slowly cruising at the same speed and not for too long.

To summarize if using water. The answer to can i use water as engine coolant is definitely no. As your cooling system is generally a 50 50 mix of distilled water and ant freeze. You can use it instead of coolant but only in emergencies.

If you are using 50 water there should be 50 coolant too.
