While water could potentially serve the purpose of heat transferring, most coolants only contain 2-4 percent water, which is subject to freezing and boiling.
The main ingredient of coolant is glycol; usually, ethylene glycol, and the rest are additives which protect your car's inner workings against corrosion, rust, and pitting caused by air bubbles imploding in the cooling system.
The D/ISHA1 is a concentrated all year round protection anti-freezing liquid type with low freezing point, designed for all engine types including full-aluminium ones.
This D/ISHA1 S Hook 1litre blue liquid protects the cooling systems against damage by freeze to -36°C and corrosion. Also the S Hook D/ISHA1 will keep you car cooler in summer months, so getting all year round protection for a great low price.
Antifreeze blue is the optimum composition of top grade ethylene glycol, combined with treated, de-mineralized water and high-performance additive package that prevents formation of rust and scum.
The S Hook antifreeze will protect and help to prolong the pump bearing service life, prevent water pump seizure and other rubber parts of the cooling system from dry out and cracking.
D/ISHA1 Antifreeze blue is notable for its high heat-transfer capacity, low viscosity, excellent detergency.
