Running faults
Produces excess smoke when running [33]
G
black smoke: fuel injector pump is over fuelling - needs re-calibration
G
black smoke: worn injector nozzles - replace
G
black smoke: dirty air cleaner - replace
G
white smoke: engine rings failed
G
white smoke: injector pump timing needs adjustment, or opening pressure is
too low
G
white smoke: value problems
G
black smoke: exhaust gas re-circulation valve failed - replace or blank off
Idles roughly
G
fuel injector pump incorrect setting
G
exhaust gas re-circulation valve failed
Engine cuts out when idling
G
air leak in fuel system
G
fuel injector pump setting
G
exhaust gas re-circulation valve failed
Engine noises
G
fanbelt rattle (intermittent): crankshaft pulley has a rubber adhesive which can
fail, eventually causing failure of engine cooling and electrical systems [14]
G
timing chain excessively worn
G
skid pan (stone guard) under engine loose
Thermal faults
Engine overheats
G
radiator effectiveness failed
G
radiator internal blockage (sludge)
G
radiator external blockage
G
Radiator obstructed by foreign matter (oil+dust, grass seeds..)
G
Radiator core collapsing
G
lack of cooling water
G
previous overheating episode
G
thermostat (at radiator top tank) blowing off at low pressure
G
Thermostat seal faulty (e.g. dirt)
G
Thermostat faulty (opening at too low a temperature)
G
loss of water
G
Rubber hose failed
G
Rubber hose perished (e.g. by solvent or time)
G
Rubber hose ruptured
G
Rubber hose rubbed through (check fan cowl on Delica)
G
Hose clamp failed or loose
G
Cylinder head gasket failed (e.g. partially)
G
extreme operating conditions
