Check of a condition of fans of the cooling system and chains of their inclusion, replacement of fans
|
Try not to touch blades a krylchatok with hands, the tool and details of clothes. In order to avoid receiving a trauma or damage of the equipment, do not start the engine at the faulty fan. Do not make attempts to repair the broken blades of a krylchatka, - change her assembled! |
CHECK
|
|
On all models equipped To/in two fans - one for an obduv of a radiator of the cooling system of the engine, and the second for an obduv of the condenser of central air are provided. The procedures described below are equally applicable to both fans. |
|
1. For check of serviceability of functioning of an electric motor of the drive of the fan disunite the socket of its conducting. Now, by means of Provo equipped with a safety lock - da crossing point connect the fan directly to the battery. If the krylchatka does not start rotating, replace an electric motor. |
2. If the motor as it should be, check a condition of safety locks of the fan of the cooling system (safety locks are placed in the assembly block which is at the left under the dashboard, on the V6 models check safety locks of #3 and #6, for the 4-cylinder - #4), the sensor(s) - the switch(es) of the fan(s), the relay of the fan of the cooling system, the K/V fan relay (the assembly block in a motive compartment) and a connecting electrical wiring of the corresponding contour.
|
on 4-cylinder models only one sensor switch of the fan of the cooling system, on the V6 models of such sensors switches two is provided ("And" and "In"). |
|
3. For check of serviceability of functioning of any of cooling system fan sensors switches, disconnect the socket of its electrical wiring. Start the engine and by means of an ohmmeter make sure of lack of conductivity between sensor switch plugs at the cold engine (below 88 °C conductivity has to be absent). Short circuit of the sensor switch has to happen after warming up of cooling liquid up to the temperature over 92 ÷ 96 °C. Temperature of short circuit of the sensor switch of the K/V condenser makes 108 °C. In case of violation of the described dependence of existence of conductivity replace the faulty sensor switch. Disconnection of each of sensors switches has to happen at a temperature at 3 ÷ 8 degrees below temperature of their short circuit. |
|
Do not leave the engine working at the disconnected sensors switches more long, than it is necessary for carrying out the described checks. Do not delay restoration of initial connection of an electrical wiring, then, having allowed the fan to rotate a little, switch off ignition. |
4. On 4-cylinder models only one thermosensitive sensor switch controlling functioning of fans of both systems is provided (coolings and air conditionings). On the V6 models of such sensors switches two - on one for each of systems.
|
5. For check of the relay of fans, take the corresponding relay from the nest in the assembly block, connect the plug 3 to the battery and ground the plug 4. The serviceable relay has to become isolated, having created conductivity between plugs 1 and 2 which has to disappear at power off. |
|
|
Check of the ventilatory module of management
|
|
1. On the V6 models functioning of the fan of the cooling system the special electronic module located under a knee emphasis of the forward passenger operates. Remove an emphasis (see the Head Kuzov). Probe plugs of each of wires from a reverse side of the socket of the module the sharp probe at two provisions of the lock of ignition (ON and OFF). Be careful - try on to puncture isolation. |
2. Make sure available conductivity between the plug of a black wire and weight. If conductivity is absent, check serviceability of a contour of grounding. 3. Make sure available battery tension on plugs of the following wires: the white, black yellow - 1, black yellow - 2, ochroleucous and yellow. If tension is absent, check a condition of the corresponding safety locks in both assembly blocks (under the dashboard and in a motive compartment). 4. Again include ignition, having restored initial connection of an electrical wiring. Ground the plug of a green wire on weight. If fans do not work, check green, yellow and ochroleucous wires for break 5. Measure tension on the plug of a white-green wire. The demanded value at a temperature of engine below 107 °C makes 11 ÷ 12 V, - whether otherwise check there is no short circuit on the mass of the case, estimate a condition of the module of management and the thermosensitive sensor switch. 6. Before testing the new module, disconnect both ventilatory relays and make sure of lack of conductivity between the plug of a yellow/ochroleucous wire and weight (establish the range of measurement of 20 KOhm on an ohmmeter). If conductivity takes place, the new module at inclusion will also fail. |
|
Replacement
|
|
The procedures described below are equally applicable to both fans. |
1. Disconnect a negative wire from the battery.
|
If the stereosystem established on the car is equipped with a security code before disconnecting the battery make sure that have the correct combination for input of the audio system in action! |
2. Cock the parking brake and prop up back wheels of the car antiretractable boots. A car front also establish to Poddomkratta it on props. At the corresponding complete set remove the lower antispray screen of a radiator. 3. Having passed a small screw-driver throughout the socket, release a lock uvula and disconnect a fan electrical wiring.
|
On the models equipped with a control system of speed, release a driving cable of a tempostat from two plastic clamps from above on casings of fans. |
|
4. On assembly of the fan of the air conditioning system turn out the lower fixing bolt |
|
5. Otboltite the fan from the top part of a radiator. |
|
6. Accurately take the fan from a motive compartment.
|
At the corresponding complete set it is necessary to take aside the driving cable of a tempostat released from clamps. |
|
|
7. For removal of a krylchatka from a shaft of the motor give the central nut. |
|
8. For removal of a driving electric motor from a casing of the fan turn out fixing screws. |
9. Installation is made upside-down. |
