Proper operation of the cooling system in trucks is important for their efficient operation. Coolant concentrate is one of the important elements of taking care of the cooling system. Choosing the right agent and its proper use can prevent failures and ensure a long engine life.
Coolant concentrate is an undiluted agent containing ethylene or propylene glycol and protective additives such as corrosion inhibitors and stabilizers. Before use, the concentrate requires dilution with distilled or demineralized water. Ready-made coolant is already a diluted preparation, ready for direct use in the cooling system.
Advantages of coolant concentrate :
economy – ability to obtain more fluid at a lower cost;
flexibility – ability to adjust the mixture proportions to climatic conditions;
ease of storage – smaller concentrate packages are more handy.
When choosing a coolant concentrate for trucks, there are several aspects to consider, such as:
engine compatibility – make sure the selected concentrate meets the vehicle manufacturer’s standards (e.g. G11, G12, G13);
cooling system protection – choose a preparation containing anti-corrosion, stabilizing and anti-foaming additives;
working temperature – check what temperature the mixture made from concentrate and water is resistant to;
manufacturer – choose proven brands that guarantee high product quality.
Correct dilution of the coolant concentrate is essential to ensure the proper mixture properties:
The standard ratio is 1:1 (50% concentrate and 50% distilled water). This mixture provides protection against freezing to about -37°C and boiling to about 108°C.
For extreme climatic conditions the proportions can be adjusted: 60% concentrate and 40% water provides protection down to -45°C.
Using concentrate instead of ready-made coolant has many advantages:
longer durability – the ability to precisely select proportions allows for better adjustment of fluid properties to operating conditions;
savings – for large commercial vehicles, concentrate is a more economical solution;
increased efficiency of the cooling system – properly prepared fluid more effectively protects the system against corrosion, deposits and overheating.
Selecting and using the right coolant concentrate for trucks is an important part of ensuring the efficiency of the cooling system. Choosing a high-quality concentrate, diluted according to the manufacturer's recommendations, can ensure optimal engine operation and minimize the risk of costly breakdowns .
