Circulation of the cooling system

If the engine is warmed (the thermostat is closed), cooling liquid circulates as follows.

For engines of the J20 models

For engines of the G16 models

When cooling liquid heats up to normal temperature and the thermostat is open, cooling liquid passes through a radiator core which needs to be cooled, and also on all above-stated chain of the movement.

G16 engine


1 — a radiator 2 — the cooling fan 3 — the thermostat 4 — the water pump 5 — a radiator admission 6 — release of a radiator 7 — an exhaust pipe	8 — a final cover 9 — the case of butterfly valves 10 — release of the heater 11 — a heater admission 12 — contour 13 — an inlet collector 14 — heater knot
