Bus PAZ

Diesel cooling is liquid with forced circulation of coolant from a centrifugal pump. The design of the cooling system is shown in Figure 1

Diesel model D-245.7EZ is installed on PAZ-32053-07 buses. Diesel model D-245.9EZ is installed on PAZ-4234 and PAZ-32053-07 buses

Combined diesel lubrication system

Oil pump - gear type, single-section

Sludge is drained from the fuel coarse filter daily. To drain the sludge you need:

Setting the fuel injection advance angle for diesel D-245.7E3 / D-245.9E3 bus PAZ 32053-07

The need to install (reinstall) the pulse wheels of the crankshaft and the fuel injection pump drive gearbox shaft to synchronize them may be caused by rearranging the fuel injection pump drive gearbox during routine diesel repairs

If a malfunction occurs during operation of the bus (the diagnostic lamp of the "COMMON RAIL" system lights up or flashes), it is necessary to diagnose the "COMMON RAIL" system using the diagnostic lamp and diagnostic key and eliminate the identified malfunctions
