Repair of the pump of cooling liquid
The pump of cooling liquid is not subject to repair and should be replaced in case of damage. After removal the pump is checked on tightness (it is visible on existence of spots of a rust) and the nave for check of bearings is turned.
Replacement and tension of a maple belt
For a drive of the units established on the engine since 1995 of release (the volume of 2.0 l of OHC and DOHC) uses so-called multicostal maple a belt. The belt stretches automatically. In the presence of the conditioner the belt in addition brings a compressor pulley into rotation. The similar belt gives in rotation the pump of the hydraulic booster of a steering.
At the engine of 2.0 l of old execution and the engine of 2.4 l maple the belt stretches generator shift. The special measuring tool which use here is not considered is applied to the correct tension of a belt in repair trucks. Generally the belt in the center of the maximum distance between pulleys should cave in on 12-13 mm under the influence of a hand thumb.
THE ENGINE OF 2.0 L OF OHC (TO THE MIDDLE OF 1995. RELEASE) AND ENGINE OF 2.4 L
As it was already mentioned, the tension of a belt is checked by the special measuring device. At temporary control the tension of a belt of the engine of 2.0 l of former model and the engine of 2.4 l is checked as follows:
| PERFORMANCE ORDER |
| 1. Press a hand thumb in the middle of the maximum distance between pulleys. Whether check there corresponds a deflection to the established size. |
| 2. If it is necessary, weaken fastening of a tension level (the engine of 2.0 l) or a nut of the tension screw (the engine of 2.4 l) and the bottom bolt of fastening of the generator and wring out the generator outside of (2.0 l) or turn the tension screw (2.4 l) so that to pull a belt. |
|
|
3. Holding the generator in this situation, tighten both weakened bolts the moment of 25 Nanometers (2.0 l) or tighten nuts of the tension screw (2.4 l). After adjustment check a belt tension. The tension screw of the engine of 2.4 l is shown on иллюстр. |
|
Replacement of a maple belt is carried out as follows:
ENGINE OF 2.0 L
Replacement is carried out after weakening of fastening of the generator as it is described above. After replacement check a belt tension.
ENGINE OF 2.4 L
In the presence of the conditioner it is necessary to remove maple a belt of a drive of the compressor before to replace a belt of a drive of the pump of cooling liquid. It is necessary to remove a belt of a drive of the pump of the hydraulic booster also.
| PERFORMANCE ORDER |
|
|
1. Weaken both nuts shown on иллюстр. shooters, also unscrew tension screws so that to weaken and remove a belt. |
| 2. Put on new maple a belt and adjust its tension the tension screw as it was described above. Tighten nuts the moment of 25 Nanometers. |

THE ENGINE OF 2.0 L FROM THE MIDDLE OF 1995. RELEASE
| PERFORMANCE ORDER |
|
1a. The scheme of laying of a maple belt of the engine of 2.0 l since 1995 of release and the DOHC engine without the conditioner. |
|
1b. The scheme of laying of a maple belt of the engine of 2.0 l from the middle of 1995 of release and at the DOHC engine with the pump of the hydraulic booster of a steering and the conditioner. |
|
|
1c. On иллюстр. 1a and 1b the scheme of laying of a multicostal belt for the engine with and without the pump of the hydraulic booster of a steering is shown. The tension of a belt is supported by automatically tension roller. It is possible to check only the mobile tension lever that is shown on иллюстр. 1c. If the tension lever (1) is not between two emphasis (2), maple a belt and a tension roller replace. Replacement is made as follows: |
|
|
2. Establish a key, as is shown in иллюстр., on a tension roller also turn it in the arrow direction (clockwise). Thus the tension of a belt weakens and it can be removed. If the belt is established again, it is necessary paint or a felt-tip pen to put the direction of its rotation on a belt. For deduction of a tension roller it is possible to insert a pin in a place designated on an illustration (1).
|
3. Put on a belt all pulleys and again delay a roller and then press it to a belt. At the first start-up of the engine the belt tension is established again automatically.
In view of that a belt multicostal, it is important to lay correctly it in flutes of pulleys. After that take out a pin from a tension roller and again release a roller on a belt.
Sometimes it is necessary to replace or remove a tension roller of a belt. In this case after removal of a belt turn a roller in the direction shown on иллюстр. point 2 so that the pin (1) entered into the opening intended for it. Turn out both bolts of a tension roller and remove a roller.
At installation the roller is again fixed by a pin (1). Bolts tighten the moment of 18 Nanometers. The belt is put on, the pin is taken out and the tension roller nestles on a belt. |
