Torn maple a belt

1–passing of a poliklinovy belt in the six-cylinder engine without climatic installation.
2–so poliklinovy the belt in the six-cylinder engine with climatic installation covers various belt pulleys

Through 120 000 km of run it is necessary to be in earnest about replacement of a maple belt of the four-cylinder engine, since at the torn belt of the water pump the engine overheats (the pump of cooling liquid without a drive). It is with guarantee noticed too late since only the control bulb of cooling liquid or the device shows defect. The driver with the six-cylinder engine can not be afraid of such defects: its water pump has a direct drive from a gear belt of the engine.

 Council: Consequences of an overheat of the engine manage expensively: defective laying of a head of the block of cylinders or – in hard cases – the broken-off head of the block of cylinders involve expensive repair. Therefore when the bulb of cooling liquid will light up, at once stop and look, whether as it should be maple a belt on belt pulleys of the water pump and сервонасоса. If is not present, tow off the car!
