What Type of Water Should Be Added to a Car's Coolant Reservoir?

[VonLondyn]

Add coolant. Below is a detailed introduction about coolant: 1. Method: Generally, coolant should be added as a mixture of half coolant and half water, and distilled water must be used. This is because the minerals in tap water can alter the properties of the coolant and prevent it from functioning properly. Therefore, never add tap water. The prepared coolant can then be poured into the reservoir through the filler neck. The coolant level should be between the minimum and maximum marks on the reservoir. 2. Reason: Water has a freezing point of 0 degrees Celsius and a boiling point of 100 degrees Celsius, whereas modern antifreeze can have a freezing point as low as -45 degrees Celsius and a boiling point above 110 degrees Celsius. This is why coolant is also referred to as antifreeze.
