Check of serviceability and replacement of the fan of the cooling system and coupling of its coupling

In order to avoid possible damages or getting injured do not start the engine with the damaged fan AT ALL. Do not try to make repair of blades of the fan - in case of damage of a krylchatka replace the fan new.

Check

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery and shake the fan back and forth a hand, checking its coupling for existence of signs of an excessive side play.
  2. At cold (and not started) the engine rotate a krylchatka of the fan manually. The fan has to rotate freely.
  3. Examine the fan outside, trying to vyvit traces of leak of liquid from assembly of the viscous coupling. In case of identification of signs of malfunction replace the coupling.
  4. At completely heated-up engine switch off ignition and disconnect a negative wire from the battery. Turn the fan manually. Small, but noticeable resistance has to be felt. If the fan rotates freely, replace the coupling.

Replacement

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery. Give fixing bolts and lift a fan casing, having bared cuts in the lower arm of a radiator, then transfer a casing via the fan.
  1. Give bolts of fastening of a casing of the fan.
Details of assembly of the fan of cooling of the V8 engine
  1. Removal of the fan on V8 engines requires the special tool which can be bought almost in any of shops of automobile accessories. The fan fastens to the water pump by means of the big central nut which is a part of the drive of the fan. The tool takes four bolts of a pulley of the pump whereas the central nut is given by a big key (a carving right and it is necessary to give a nut counterclockwise). Sometimes the pulley of the pump can be recorded, rather strongly having pressed tape type a driving belt, however in case the fan staid on the car already long enough, use of the tool is inevitable. The fan of the 6-cylinder engine fastens to the water pump by means of four hairpins with nuts; give nuts and remove the fan assembled with a clutch coupling from hairpins.
  2. Take assembly of the fan with the coupling and its casing from a motive compartment.
  1. Take assembly of the fan with the coupling and a casing.
  1. Carefully survey a condition of blades of a krylchatka. In case of detection of defects make replacement of the fan.
  2. At this stage the krylchatka can be an otbolchena from a clutch coupling (if in it there is a need). It is necessary to store the fan, having laid the party turned to a radiator down.
  1. Give four bolts and separate a krylchatka from a clutch coupling - it is necessary to store the coupling stacking surely DOWN the party turned to a radiator.
  1. You make installation upside-down. Track reliability and uniformity of tightening of nuts of fastening of a krylchatka and the coupling.
