Remember that the 50 - 50 mixture of the two is recommended in the extremely cold weather so that the water won’t freeze. Taking that for reference, with quite high temperatures in our tropical climate, Philippine car owners may use a proportion of 20-80 car coolant and distilled water or even higher of 10-90.
Also, keep in mind we’re referring the true distilled water, not the one that is always available in your house that contains minerals, to impede lime scales’ forming in the cooling system.
Car coolant can be purchased online from popular e-commerce platforms such as Shopee and Lazada. According to these websites, car coolant price in the Philippines starts at around Php 300 for 1 liter.

Apart from the coolant, rust inhibitors are also found in the different cooling system additives which augment the water’s heat transfer properties. All these additives work the same process which is to reduce the water’s surface tension, providing more surface room against the cooling system.
Waterless car coolant can also be an option. Using this product in a pressureless cooling system, the rubber hoses could survive along with the car and leaks are optimally avoided.
