ET035LOW SPEED ENGINE FAN
RECOMMEND AT IONS No failure on the water temperature sensor circuit must be present in
order to perform this diagnostic.
Check:
- engine fan condition
- engine fan resistance condition
- condition f the engine fan mass connection
-l ow speed engine fan supply
-s upply line between engine fan and engine fan relay
M end if necessary.
C heck the connection and condition of the connector of the low speed engine fan relay
Re place the connector if necessary.
Rem ove the rela y of the low spe ed engine fan
C heck, with the contact set on, the supply presence +12 volts at pole 1 of the rela y.
M end if necessary.
Measure the relay coil resistance.
Re place the rela y of the low spe ed engine fan, if necessary.
Connect the 90 ways terminal box instead of the computer and check the in su la t i on, continuity and
absence of the parasite resistance on the connection between: Pin 8 injection computer > Relay of the low speed engine fan
M end if necessary.

Carefully position the engine fan assembly in the guiding points (4).
Mount the attachment screws ( 3) of the assembly on the radiator.
Connect the engine fan connector ( 1).
Attach in clips the wiring in point ( 2).
Attach in clips the power steering oil reservoir on the battery screen.
Mount the air inlet pipe.
Connect t he battery (-) terminal. In case the vehicle is equipped with programmable
r adio-cassettes player, e lectronic clock, etc, there are t o be re-programmed before returning
the vehicle to the client.
Check the engine fan operation: start the vehicle engine and disconnect the water
