Repair and car operation

Check of a condition of the fan (ов) systems of cooling and chain of its inclusion, fan replacement (ов)

Check

On the models equipped To/in, two fans – one for обдува a radiator of system of cooling of the engine, and the second for обдува central air condenser are provided. Described below procedure are equally applicable to both fans.

PERFORMANCE ORDER

1a. For check of serviceability of functioning of the electromotor of a drive of the fan disunite the socket of its conducting (see иллюстр.: cooling system). Now, by means of a wire crossing point connect the fan directly to the battery. If the fan does not start to rotate, replace the electromotor. 1b. Location раъема electroconductings of the driving motor of the fan of central air of air. 2. If the motor as it should be, check a safety lock and relay condition (see. Head Onboard electric equipment), the sensor switch of the fan, the To/in fan relay (at the corresponding complete set it is established in the left forward corner of an impellent compartment) and connecting electroconducting of the corresponding contour. 3. For check of serviceability of functioning of the sensor switch of the fan of system of cooling, disconnect the socket of its electroconducting (see an accompanying illustration), then by means of an ohmmeter make sure of lack of conductivity between sensor switch plugs at the cold engine (below 88°С conductivity should be absent). Start the engine, warm up it to normal working temperature, then again muffle and make sure that now (at temperature of cooling liquid is higher 92÷96 than °C) conductivity between plugs of the socket takes place. In case of negative results of checks replace the sensor switch. 4. Functioning of the fan of central air of air is supervised by the electronic module of management (ESM). If the fan does not function at inclusion To/in in spite of the fact that all checks described in the previous paragraph yield positive result, check coolant level in system. Diagnostics of ESM can be made in the conditions of a car-care center workshop.

Replacement

PERFORMANCE ORDER

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 audiosystem input in action! 2. Cock the parking brake and prop up back wheels of the car protivootkatny boots. To Poddomkratta a car front also establish it on props. At the corresponding complete set remove the bottom antispray screen of a radiator. 3. Having passed a small screw-driver in the socket, release a lock uvula and disconnect fan electroconducting. 4a. Turn out the bottom bolts of fastening of the fan (see accompanying illustrations). 4b. On the Integra models the clamp, on the Civic models – two rubber pillows placed in openings in basic arms is provided. 5. To Otboltita the top arms of the fan (ов) (see an accompanying illustration) and the top support of the condenser. 6. Accurately take the fan from an impellent compartment (see an accompanying illustration). 7. For removal of a krylchatka from a shaft of the motor give the central nut (see an accompanying illustration). 8. For removal of the driving electromotor from a casing of the fan turn out fixing screws (see an accompanying illustration).
