Removal, check and installation of coils of ignition

REMOVAL

1. Disconnect a cable of weight from the battery.

If the autoradio tape recorder in your car is coded before to disconnect the battery, be convinced that you know a code.

REMOVAL

1. The high-voltage coil of ignition is attached by bolts to a forward part of the block of the amplifier which is established on the right party of a partition of an impellent compartment. Pay attention that Renault does not deliver the ignition coil separately from the module-amplifier, but it probably to get from other sources. 2. Disconnect a wire of a high voltage from the ignition coil, then disconnect electroconducting from the module-amplifier. Turn away bolts of fastening of the coil of ignition and accurately remove the coil of ignition from the module-amplifier.

REMOVAL

4a. Ignition coils are established on the right end клапанной covers (address to an accompanying illustration). 4b. Remove the ignition coil. 5. Let out from fastenings and remove a plastic cover from a forward part of assemblage of the coil of ignition. Uncouple high-voltage conducting of spark plugs from a clamp, then turn away screws, fastening a clamp to assemblage of the coil of ignition and move a clamp aside. 6a. Turn away screws. 6b. Disconnect high-voltage conducting from spark plugs. 7. Disconnect the multicontact tip from ignition coils (address to an accompanying illustration). 8. Release electroconducting from the holder on the right end of assemblage. 9. Disconnect a separate wire of the condenser (address to an accompanying illustration). 10. Turn away a fixing bolt probeа measurements of level of impellent oil (address to an accompanying illustration). 11a. Turn away four fixing screws. 11b. Cнимите assemblage of the coil of ignition together with ВВ wires with клапанной covers. Pay attention that screws are established from above screws клапанной covers (address to illustrations). 12. Accurately disconnect high-voltage conducting of spark plugs from ignition coils (address to illustrations). The bases of coils of ignition various to provide their installation only in one position.

REMOVAL

1. Ignition coils are established on the forward party of the engine. 2. Disconnect high-voltage conducting from spark plugs. 3. Disconnect the multicontact tip from coils of ignition and a separate wire from the condenser. 4. Turn away four screws, fastening each coil of ignition to a fixing arm and remove ignition coils together with ВВ wires of spark plugs. The bases of coils of ignition various to provide their installation only in one position. 5. Accurately disconnect high-voltage conducting from ignition coils.

REMOVAL

1. Ignition coils are united in the assemblage established in the centre клапанной of a cover. Ignition coils are planted directly on candles and high voltage wires are not required. Ignition coils cannot be separated from assemblage and in case of malfunction of any coil it is necessary to replace all block (address to an accompanying illustration). 2. Where is available, remove a core of a coupler of a forward suspension bracket over the engine. 3. Turn away two screws and remove a plastic cover from top of assemblage of the coil of ignition. 4. Disconnect the multicontact tip of conducting on the assemblage end. 5. Turn away seven fixing screws and remove coils of ignition from candles ignitions.

CHECK

1. Check of serviceability of the coil of ignition is reduced to a procall of its windings (between clips “+” and “-” primary, and between clips LT + and НТ secondary). Compare the received results with specified in Specifications in the beginning of this Chapter. Notice that resistance of windings of the coil of ignition can change slightly depending on coil temperature, results in Specifications - approximate as no exact data is specified Renault. 2. Check up, that between the plug of a wire of a high voltage and the case of the coil of ignition was not available any электропроводности. 3. If the ignition coil is defective, replace it.

CHECK

1a. Each coil of ignition can be checked up a multimeter in a mode of measurement of resistance. Attach a multimeter to plugs and compare the received results of measurements to the information presented in Specifications. Three plugs of a low-voltage chain are noted by numbers on a nest. 1b. In conclusion of test attach a multimeter between two ВВ plugs (address to illustrations). 2. Replace the ignition coil if it is defective, but remember that they are various.

CHECK

1. Each coil of ignition can be checked up a multimeter in a mode of measurement of resistance. Attach a multimeter to plugs and compare the received results of measurements to the information presented in Specifications. Four low-voltage plugs are numbered from 1 to 4, the plug №1 - the nearest to a partition of an impellent compartment. Attach a multimeter between ВВ plugs for cylinders №1 and №4, and then - for cylinders №2 and №3. 2. Replace assemblage of the coil of ignition if any of windings is defective.

INSTALLATION

1. Make installation upside-down, watching that electroconducting sockets were correctly and are reliably fixed.
