Frost resistance check The special device – the areometer is necessary for you for check of frost resistance of cooling liquid. It measures the specific weight of liquid. Because of various means of protection from corrosion specific the weight of additives are not identical to protection against freezing. For safety it is worth taking away also the admission of 2 — 3 °C.
Control of concentration of antifreeze In most cases it appears that concentration of cooling liquid is already insufficient. Then it is necessary to add a little means from freezing; by rough calculations about 1/4 l on each 10 °C norms are lower.
