Removal and radiator installation As a result of long operation of the car thin channels in a radiator can get littered with the deposits containing in the cooling liquid, and limy adjournment. Thereof efficiency of cooling and the engine essentially decreases overheats. Unique way of correction of a situation is radiator replacement.
If oil gets to a cooling contour, for example, at defect of a sealing lining of a head of cylinders, after the spent repair it is necessary to remove a radiator and a broad tank and to wash out usual clearing means. Observe thus instructions of the manufacturer of clearing means. After radiator installation into place it is necessary to fill some times all system of cooling with hot water and to merge it.
| |
The liquid after washing cannot be poured out. Observe instructions of its manufacturer. Local authorities should give the information on places of possible recycling of similar liquids. |
| |
| 1 Remove a fan casing, address to Section Removal and installation of the fan/casing of the fan.
2 Merge cooling liquid and utilise it, address to Section Replacement of a cooling liquid.
3 Petrol engine: Remove a box of the air filter on всасывании, address to Section Removal and installation of the air filter of the engine.
4 Disconnect hoses of a cooling liquid from above and from below on a radiator. For this purpose by means of a small screw-driver remove upward clamps quick disconnect муфт, address to Section Connection and separation quick disconnect муфты.
5 Disconnect from below at the left at a radiator a cable of the gauge of level.
|
6 Turn out at the left above at a radiator the screw-1.
| |
The corresponding screw on the right at a radiator has been turned out already at removal of a casing of the fan. | | 7 Incline a radiator above back, then take out upwards from the bottom holders.
| |
Radiators of the hydraulic booster of a wheel and the conditioner are located before an engine radiator in the holder of the module. For removal of these radiators it is preliminary necessary to remove an engine radiator. It is authorised to open a contour of cooling of the conditioner only with the specialised workshop having corresponding equipment. There is a danger of accident, address to Section 11.
Radiator plates have sharp edges, therefore it is recommended to use for radiator removal mittens. | | |
| |
| 8 Check up all hoses of system of cooling on presence of cuts, cracks and other damages. If it is necessary, replace them. Check up a condition of both bottom rubber support of a radiator.
|
9 Insert a radiator from above so that rubber support have sat down precisely in overlays (black arrows on an illustration).
10 Incline a radiator forward and screw the top screw from outside a branch pipe for filling with water. | 11 Establish a fan casing, address to Section Removal and installation of the fan/casing of the fan.
12 Attach a cable to the level gauge at the left below at a radiator.
13 Check up visually sealing rings in quick disconnect муфтах. In the presence of deformations replace.
14 Press wire clamps on муфтах. Connect to a radiator hoses. Thus quick disconnect муфты should be latched distinctly, address to Section Connection and separation quick disconnect муфты.
15 Petrol engine: Establish a box of the air filter for soaked up air, address to Section Removal and installation of the air filter of the engine.
16 Fill system with a liquid and remove from it air, address to Section Replacement of a cooling liquid. | |
