The high-speed idle screw is factory sealed and cannot be adjusted. Low-speed idle can be adjusted. 1. Use an optical tachometer such as Snap-on No. MT139 or MTE (Cummins tool division) No. 3377462 to read the engine RPM. 2. Bring the engine to normal operating temperature. 3. Adjust the low idle speed at the low idle speed screw. The screw and locknut are located at the rear of the fuel injection pump. 4. Loosen the idle screw lock nut. Adjust idle screw to obtain specified RPM. LOW IDLE SPEED With automatic transmission: 750-800 RPM with transmission in drive and air conditioning on. With manual transmission: * 780 RPM with transmission in neutral and air conditioning on. * With engine at operating temperature. HIGH IDLE SPEED Do not attempt to adjust high idle speed. High idle speed adjustment screw is factory sealed. Breaking seal will void injection pump warranty 5. Tighten the locknut after adjustment.

Incidentally, that Renaultsport 172 deserves a special mention, because it looks as though it could well be the new king of the hot hatches, thanks to the blistering performance provided by its 172bhp, two-litre, 16-valve engine and lowered chassis. We’ve driven it and will be reporting on it in due This new twin-cam unit is already used in the Megane and Scenic and certainly deserves this wider application because it’s a real little sweetie, whose “warm hatch” performance belies its capacity – curious that Renault insists that size matters! While happy to tip-toe through traffic, it really comes alive out on the open road. Not only is it smooth and quiet, but take it beyond 3000rpm and it’s a decidedly swift performer that loves to rev yet still manages to remain mechanically refined. Complementing the new engine are the deft gearchange and nicely weighted clutch that give added driving pleasure. Such is the way that the powertrain is mounted, however, that the gear lever gives an unseemly lurch forward as you back off the accelerator

The lamp illustrated is an oil level low warning indicator and not a service interval indicator. When the engine oil is at the correct level, this lamp will automatically extinguish. The lamps illustrated above, are Malfunction Indicator Lamps (MIL) and not service interval indicators. When illuminated there is a problem with the vehicle. Refer to manufacturer’s documentation for further information.

Special tooling required Mot. 1732 Tool for removing and re?tting the alternator pulley Tightening torquesm the alternator decou- pling pulley I – PARTS AND CONSUMABLES FOR THE REPAIRS Parts always to be replaced: – the alternator belt, – the tensioning roller, – the mechanic tension wheel mounting bolts. II – PRECAUTIONS DURING REPAIR It is essential to replace an alternator decoupling pulley with a decoupling pulley. III – EQUIPMENT REQUIRED – Torque wrench capable of tightening a left-hand thread. IV – REMOVAL Remove the vehicle alternator (see 16A, Starting – charging, Alternator 110276 110268 Position adapter (2) from the tool kit (Mot. 1732) (corresponding to the alternator rotor recess) in the hexagon socket (1). 110267 Position the hexagon socket (1) from the tool box (Mot. 1732) in the alternator pulley. 110269 Position the adapter holder (3) in socket (2). 110270 Hold the hexagon socket (1) using an open-jawed spanner (4). Loosen the decoupling pulley (5) using a ratchet, (6) (turning it in the clockwise direction.). Remove the decoupling pulley. V – REFITTING Position: – the hexagon socket in the alternator (1), – the adapter (2) (corresponding to the alternator ro- tor mark), – the adapter holder (3) on the adapter(2). Note: Check that the torque wrench is capable of tigh- tening in an anticlockwise direction. 110266 Screw the new decoupling pulley onto the alternator rotor. Tighten to torque the alternator decoupling pulley (80 Nm) using a torque wrench(7). Refit the vehicle alternator (see 16A, Starting – charging, Alternator).

NOTE : a. Checking the idle mixture adjustment will require the use of the on/off ratio tester (Bosch KDJE-P 600) or equivalent. b. All tests are to be performed after engine has reached normal operating temperature. c. All accessories must be switched off. d. The engine must be in good mechanical working order and free from electrical misfires. Fig. 72 Bosch On/Off Ratio Tester 1. Connect the on/off ratio tester to the diagnostic socket. 2. Disconnect the purge line to the throttle valve assembly at the purge valve and plug it. 3. Start the engine and run at idle speed. 4. Press the IR 100% button on the tester. 5. Run the engine at approximately 2500 RPM and record the average on/off ratio reading. NOTE: If the On/Off ratio tester has a constant value refer to DIAGNOSIS AND TESTING PROCEDURES in COMPUTERIZED ENGINE CONTROLS . 6. Let the engine return to idle speed and wait a few moments for it to stabilize. Now record the average on/off ratio reading at idle. The On/Off ratio reading should be in the 50% ±10% range, and the difference between cruise and idle RPM should not vary by more than +10. If the difference is greater than +10 refer to ADJUSTING THE AIR/FUEL MIXTURE . If the difference is not greater than +10 the fuel mixture is adjusted correctly.
