Honda Accord

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 #3 and #6, for 4-cylinder - #4), the sensor(s) - the switch(es) of the fan(s), the relay of the fan of the cooling system, the relay of the K/V fan (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 ÷ of 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 ÷ of 8 degrees below temperature of their short circuit.

Do not leave the engine working at the disconnected sensors switches longer, than it is necessary for conducting 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.

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: 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 required value at a temperature of engine below 107 °C makes 11 ÷ 12 V, - otherwise check whether 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 on an ohmmeter measurement range 20 KOhm). If conductivity takes place, the new module at inclusion will also fail.

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 you 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 the 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.
