Fig. 467. Elements of the cooling system located on the engine: 1 - bolt, 20 Nm; 2 - pulley; 3 - poly V-belt; 4 - bolt, 10 Nm; 5 - coolant pump; 6 - bolt, 20 Nm + 90°; 7 - sealing ring; 8 - clamp; 9 - temperature sensor; 10 - holder; 11 - oil radiator; 12 - connecting element; 13 - hose to the bottom of the radiator; 14 - thermostat; 15 - gasket (always replace); 16 - nut, 30 Nm; 17 - bracket; A - to the radiator; B - to the heater radiator; C - from the heater radiator
Fig. 468. Coolant pump: 1 - bolt, 20 Nm; 2 - coolant pump; 3 - bolt, 10 Nm; 4 - bolt, 10 Nm; 5 - coolant temperature sensor, 7 Nm; 6 - thermostat; 7 - bolt, 10 Nm; A - attached to the cylinder head; B - to the heat exchanger; C - to the heater radiator; D - from the radiator
The coolant pump is located to the right of the engine and is driven by a poly V-belt from the engine crankshaft (Fig. 467). In Fig. 468 the pump is shown separately.
Procedure for removing the coolant pump:
- turn off the battery;
- place the front of the vehicle on supports and remove the crankcase guard;
- drain the coolant from the cooling system (see paragraph 19.1.1);
- loosen the coolant pump pulley bolts while the belt is on;
- remove the poly V-belt;
- remove the coolant pump pulley;
- unscrew the four crankshaft pulley bolts and remove the pulley;
- remove the lower part of the drive belt guard;
- loosen the hose clamps where they connect to the pump and disconnect the hoses;
- loosen the pump mounting bolts and remove the pump from the cylinder block. Remove the sealing ring and check its condition. Another sealing ring is located between the pump inlet pipe and the coolant pump housing.
The pump is installed in the reverse order. The tightening torque of the pump and pulley bolts is 20 Nm.
Install the poly V-belt and adjust its tension as described in p. 19.3.3.
Fill the cooling system with coolant (see paragraph 19.1.1).
