Removal and installation of the water pump

Removal

 PERFORMANCE ORDER

    Empty cooling system. Disconnect a negative wire from the battery. Remove the top hose of a radiator. Give screws of fastening of the top casing of a radiator, release clamps (having compressed them) fastenings of the top casing to bottom and take the top casing from an impellent compartment of the car. Weaken an adjusting bolt of the generator and remove a driving belt (belts) from a pulley of the water pump. Give nuts of fastening of the coupling of coupling of the fan and a pulley to a flange of the water pump, remove washers. Separate the fan, assembly of its coupling and a pulley from the water pump and remove components from the car. On models of 3.0 l:
      Remove a gas-distributing belt; Give bolts of fastening of the water pump, remembering length and location of each of them.
    On models of 4.2 l give bolts of fastening of the water pump to a cover of a gas-distributing chain and remove the pump from a cover (components of the water pump of models of 4.2 l are shown on an accompanying illustration).
1 — bolts
2 — the fan
3 — coupling assembly
4 — a pulley
5 — the water pump
6 — nuts
7 — washers
    Check the case and a pump rotor on existence of traces of corrosion, cracks and other defects. Check люфт the bearing in the pump case, estimate level of the noise published by the bearing at rotation of the pump. Check conditions of assembly of coupling, turning it manually. Rotation should occur without breakthroughs and jamming points, to easy resistance. The knot is not maintainable and in a case failure is subject to replacement.

In view of features of a design of the water pump its repair is represented inexpedient. Originators of this Management recommend to make in default pump replacement assembled.

Installation

 PERFORMANCE ORDER

    Installation is made upside-down. Make sure of purity of interfaced surfaces of the water pump and the engine, - on them should not remain any traces of old hermetic. Impose on an interfaced surface of the pump a hermetic pillow section of Ø 2 ÷ 3 mm. Track, that hermetics it was imposed from the interior of boltovy openings.
    On models of 3.0 l:
      Establish the pump on the block of cylinders and tighten bolts of its fastening in an order and with the effort, shown on an accompanying illustration, where: And = 16 ÷ 21 Nanometers, In = 7 ÷ 8 Nanometers, With = 30 ÷ 40 Nanometers. Establish into place a gas-distributing belt.
    On models of 4.2 l establish the water pump on a cover of a gas-distributing chain and tighten bolts of its fastening with demanded effort (see size tables and adjustments at the end of the Management). Establish on the pump a driving pulley, assembly of coupling and the fan. Tighten fixing nuts with demanded effort. Establish a driving belt (belts) and adjust effort of its (their) tension. Establish the top casing of a radiator and strongly tighten screws of its fastening. Connect a negative wire to the battery. Establish into place the top hose of a radiator and fill in in system necessary amount of cooling liquid of a demanded grade (see size tables and adjustments at the end of the Management). Start the engine and check it on existence of leaks.
