FAQ
This section contains answers to most frequently asked questions about coolants and brake fluids, engine and transmission oils, and windshield washing liquids.
DOT 3 fluids are used in most vehicles and intended for operation in unloaded brake systems of vehicles with disk and drum actuators. The essential advantage of these fluids is their low price. However, brake fluids of DOT 3 class are rather hygroscopic, i. e. they absorb water quickly enough.
There is no difference between them; cooling fluid is the antifreeze fluid which refers to traditional coolants. There are Tosol 30 and Tosol 40, for example. The first fluid is intended to operate at a temperature not below - 30 °С, the second one – not below - 40 °С.
Fluids of the same color can have completely different compositions and multicolor fluids, on the contrary, can prove to be the same. This is not connected with chemical composition of fluids.
It depends on the coolant base and averages to 1–3 years. However, there are products, for example, monoethyleneglycol-based red antifreeze fluid VAMP, which fulfil properly their functions during 5 years.
This information should be specified on the product label. The shelf life of engine oils manufactured by Cherkasy Automobile Chemicals Plant is 5 years.
The coolant level should be checked once in 3–6 months. If you are sure of leakage, add the antifreeze fluid recommended in the vehicle operation manual. If the coolant boils off, add only distilled water to the system.
This may have different reasons, for example, low oil level, oil pump failure, oil pressure transmitter failure, etc. In any case, the engine must be off as soon as possible because further operation may lead to a major damage.
