Warning: Do not allow antifreeze to come into contact with the skin of the body or the painted surfaces of the vehicle. If antifreeze gets in, rinse with running water. Avoid ingesting antifreeze, which is highly toxic. Do not store antifreeze in open containers, and do not leave it in the form of puddles on the garage floor or asphalt; Children and pets attracted by the sweet smell may drink it. Dispose of used antifreeze in accordance with current environmental protection requirements. Do not pour antifreeze onto the ground or down a drain.
Caution: manufacturers recommend using only antifreeze in these systems «DEX-COOL», which has an extended replacement interval. It is prohibited to mix green ethylene glycol antifreeze into orange antifreeze of the specified brand, which does not have silicate components, since this reduces the effectiveness of the latter, which is intended for operation over a mileage of 160,000 km (or 5 years).
The cooling system should be filled with antifreeze solution «DEX-COOL», which does not freeze until at least -30°C. This coolant prevents corrosion and has an increased boiling point.
The engine cooling system should be flushed and the coolant replaced in accordance with the maintenance schedule (see chapter 1). Neglecting periodic replacement leads to the formation of corrosive deposits in the system and reduces its efficiency.
Before adding antifreeze to the system, inspect its connections. Antifreeze has increased fluidity and can seep through the smallest cracks and holes. As a rule, there is no intense consumption of coolant - if the level constantly decreases, inspect the system for leaks.
The concentration of the antifreeze solution depends on the weather conditions in which the car is operated and ranges from 50-70%. Before adding antifreeze, read the instructions on the container it comes in. You can use a hydrometer to check the concentration of the solution (see illustration). Use antifreeze that meets the manufacturer's specifications.
