This system differs by the absence of a scavenge pump . Fuel supply system . (26) Fuel tank . (27) Priming pump fitted in parallel on the fuel supply circuit . (28) Diesel filter with integral heater water detector . (36) Water bleed screw . (29) High pressure pump . (30) Common rail with integral high pressure regulator . (31) Injectors . (32) Inlet and outlet valves . (33) Fuel temperature sensor . 18 2 MONOBLOC DIESEL FILTER (34) Monobloc diesel filter . (E) Intake of fuel from the tank . (S) Fuel outlet towards the high pressure pump . (35) Filtering element . (36) Water bleed screw . (37) Electric diesel heater (removable) . (38) Position of the water in diesel detector (removable) . Filtration of impurities larger than 5 microns . Fuel filter replacement interval (without heater or water detector) : ? normal servicing : 60 000 km (37 290 miles) ? arduous conditions maintenance : 45 000 km (27 967 miles) 19 COOLING SYSTEM (39) Expansion chamber . (40) Cooling radiator . (41) Water outlet housing with integral thermostatic valve . (42) Heater matrix . (43) Water inlet manifold with drain screw (for very cold countries, the rod is fitted in place of the drain plug) . (43a) Fitting with drain plug (for all countries except very cold countries) . (43b) Fitting of a heating rod . (44) Coolant pump . (45) Oil/coolant cooler . The coolant is of the lifetime type . The coolant pump is driven by the timing belt . The connection between the pump and the water outlet housing is provided by a rigid pipe with sealing provided by an oring on the pump side and by a clickon seal on the upper pipe and by crimping on the lower pipe on the water outlet housing side . The water outlet housing is secured on the cylinder head on the engine flywheel side by 4 bolts, the sealing is provided by an elastomer oring . 20 DRIVING OF THE BELTS The ancillary drive belt is of the polyvee type . There are 2 possibilities (depending on the vehicle and the level of specification) . (46) Crankshaft pulley . (47) Alternator pulley . (48) Automatic roller tensioner . (49) Roller tensioner .
