1997 RENAULT KANGOO check engine

STARTING - CHARGING
Alternator
16
If the electrical supply measured is too low, check:
- the wear of the alternator (brush...),
- the battery connections,
- the engine earth strap,
- the conformity of the alternator,
- the belt tension.
If the electrical supply measured is correct and the regulated voltage is too low, the alternator is not faulty.
The cause of the problem is to be attributed to one of the following sources :
- the vehicle has too many electrical consumers,
- the battery is discharged.

REMOVAL
Place the vehicle on a two post lift .
Disconnect the battery as well as all electrical
connections leading to the alternator.
Remove :
- the alternator belt and that of the power as-
sisted steering pump for the D7F engine (if
fitted),
- the alternator.
REFITTING
Refitting is the reverse of removal.
D7F Engine
Tensioning of the alternator belt is carried out
using the locally manufactured tool shown be-
low (threaded rod 100 mm in length (X) and three
M6 nuts).

OPTIMA 5800 Diagnostic station
CHECKING THE STARTER MOTOR USING THE DIAGNOSTIC STATION
Checking of the starter motor is carried out using the OPTIMA 5800, by measuring the battery voltage and
the current absorbed in the engine starting phase. The following operation faults may be highlighted :
- a fault in the battery ( the voltage falls during the starting phase),
- locking of the starter motor (the current absorbed is too high),
- a fault in the engine starter gear (the current absorbed is too low).
In order to carry out the measurement, it is necessary to stop the vehicle from starting :
- for D7F and E7J engines : disconnect the engine speed sensor (located on the clutch housing ,
- for
F8Q engines : disconnect the pump electrical solenoid and isolate the terminal.
NOTE :
- an open circuit on the engine speed sensor or the ignition creates a fault memorised by the injection
computer, this fault must then be erased from the memory using the
XR25 (see "Injection" section),
- if the engine is fitted with an immobiliser, it is sufficient to lock the doors using the remote control.

- the front right hand wheel ,
- the driveshaft pin using punches B. Vi. 31-01,
- the upper shock absorber bolt and slacken the
lower bolt.
Tilt the hub and release the driveshaft assembly
from the gearbox.
Remove the starter connections , as well as the
mounting bolts and extract these from the bot-
tom of the vehicle.

INJECTION
Coolant temperature management
244Injection coolant temperature sensor and
coolant temperature indication on
instrument panel.
3 track sensor, of which two tracks are
allocated to the injection coolant
temperature information, and one to the
indication of the coolant temperature on
the instrument panel.
259Warning coolant temperature switch for
instrument panel.
Operating principle
Sensor 244 allows :
- the coolant temperature to be shown on the
instrument panel,
- the injection computer to receive constant in-
formation on the engine coolant temperature
.
The injection computer, depending on the co-
olant temperature, controls :
- the injection system,
- the cooling fan assembly.
The engine cooling fan assembly is controlled
at fast speed (both slow and fast speeds are
controlled by the air conditioning system) if
the temperature is greater than 99°C. If the
temperature falls below 96°C, it cuts off
automatically ( if a check has to be carried out,
ensure that the air conditioning is not opera-
tional).

COOLING
Filling and bleeding
19
There is no heater matrix water control valve.
Water flow is continuous in the heater matrix,
which contributes to the cooling of the engine.
FILLING
Check the tightening of the drain plug(s).
Open the two bleed screws.
Fill the circuit through the opening in the expan-
sion bottle.
Tighten the bleed screws as soon as the liquid
flows in a continuous jet.
Start the engine (2 500 rpm).
Adjust the level by overflow for a period of about
4 minutes .
Close the bottle.
BLEEDING
Allow the engine to run for about 10 minutes at
2 500 rpm, until the fan(s) operate (time necessary
for automatic degassing).
Check the liquid level is at the "Maximum" mar-
ker.
DO NOT OPEN THE BLEED SCREWS WHILST THE
ENGINE IS TURNING.
RE-TIGHTEN THE EXPANSION BOTTLE CAP WHILST
THE ENGINE IS WARM.
