Removal and radiator installation

In the course of long operation of the car channels in a radiator can be narrowed as a result of adjournment of the lime containing in cooling liquid. Thereof efficiency of process of cooling and the engine sharply decreases overheats. In this case it is necessary to change a radiator.
If oil got to a radiator, for example, owing to defect of sealing laying of a head of cylinders, it is necessary to remove and wash out a radiator and a broad tank after repair by a cleaner. This purpose needs about 2 l of a cleaner. After installation of a radiator it is necessary to fill several times all system of cooling with hot water and to merge it. Water after washing of system should be utilized as appropriate.

 REMOVAL

1. Remove the fan, address to the Section Removal and installation of the fan and the fan coupling.
2. Merge cooling liquid and utilize it, address to the Section Replacement of liquid of system of cooling. Check of frost resistance of a cooler. Visual check of system of cooling.

3. Remove hoses of cooling liquid of big diameter from above and from below a radiator, previously having opened collars. Address to an accompanying illustration.

4. Disconnect a cable from the sensor of level (13) at the left below at a radiator. Address to an illustration before the table.
5. In the presence of the conditioner расстыкуйте shtekerny connection of the thermorelay (10) on the right at a radiator.

6. Remove hoses of an oil radiator (if it is available) AT for a radiator. Collect the flowed-out oil and utilize it. Hoses close, that dirt did not get to them. Address to an accompanying illustration.

Radiators of the power steering, the conditioner and, as a rule, AT are before an engine radiator in the holder. For removal of these radiators it is necessary to remove an engine radiator previously. It is necessary to open a contour of cooling of the conditioner only on HUNDRED with application of special means. There is a danger of accident.

7. Remove a sealing uvula (1) upward. Unscrew bolts (2) at the left and on the right. Remove both holders of a radiator (3). Address to an accompanying illustration.

8. Take out a radiator upward.

Plates of a radiator have sharp edges. Therefore for removal of a radiator it is recommended to use mittens.


 INSTALLATION

1. Check all hoses of cooling liquid on existence of cuts, cracks and other damages. If it is necessary, replace them. Check both rubber support of a radiator.

2. A radiator insert from above so that rubber support rose precisely into place. Address to an accompanying illustration.

3. Press a radiator and fix holders. Press on a sealing uvula.
4. Fix oil hoses of AT with new consolidations on a radiator. Moment of an inhaling of 20 Nanometers. Check AT oil level, address to the Section Check of level and replacement of oil of automatic transmission.
5. Put on hoses of cooling liquid and fix them collars.
6. Connect a cable at the thermorelay and the level sensor if they were disconnected.
7. Establish the fan, address to the Section Removal and installation of the fan and the fan coupling.
8. Fill system with liquid and remove from it air, address to the Section Replacement of liquid of system of cooling. Check of frost resistance of a cooler. Visual check of system of cooling.
9. Start and warm up the engine and check shlangovy connections on tightness.
10. Check level of cooling liquid, if necessary add.
