Never remove a stopper of a radiator and do not weaken a drain stopper of a radiator at the working or hot engine and a hot radiator.

Fig. 2.210. Components of system of cooling of Mazda 3 cars: 1–radiator; 2–radiator cover; 3–thermostat; 4–the pump of cooling liquid; 5–blade of the fan of system of cooling; 6–engine of the fan of system of cooling No. 1, engine of the fan of system of cooling No. 2; 7–L3 engines; 8–LF engines, except for L8 engines

Uncovering a radiator, it is necessary to show care (fig. 2.210).
Stop the engine and let's to it cool down.
Wrap up a thick fabric round a cover and slowly turn it counter-clockwise to the first limiter.
Depart from a radiator for the period of pressure dumping. Be convinced that pressure fell, press on a cover, without removing from it a fabric, turn on and remove it.
