Serpentine Belt Diagram: check serpentine belts auxiliary units Lexus RX300 .

______________________________________________________

Compact off-road car Lexus RX-300 of a category "lux" has appeared in the market in 1998. On considered models establish engine V6 of 3.0 l. Capacity of 223 h.p. the Four-stage automatic transmission (АТ), united with an interaxle differential by means of viscous clutches, provides a constant all wheel drive with equal distribution of a twisting moment between shafts. The rear bridge is equipped by differential with viscous a clutch of restriction of slippage. The models intended for the American market, can have a drive gear only on front wheels, on these models is applied modified 4-step АТ (without an interaxle differential). Serpentine Belt Diagram tells about condition check serpentine belts Lexus RX300 . Too low tension serpentine belt conducts to its raised deterioration or fast failure. At too high tension there can be damages of bearings of the units, resulted to data belt. It is necessary to check periodically a condition serpentine belt, and at detection of defects, to replace belt.
PERFORMANCE ORDER
1. Fingers walk on all length serpentine belt, feeling it on presence of cracks and stratifications. Also check up, whether is not present on serpentine belt attritions and polish to shine of sites. Serpentine belt it is necessary to inspect from both parties that means its necessity twisting. Be in passing convinced of absence of a rust, cracks and agnails on pulleys. On a work face serpentine belt presence of superficial perpendicular cracks is supposed. If these cracks do not overstep the bounds of one edge and not so deep, to replace serpentine belt there is no necessity.
