In a workshop with special equipment, the radiator can be checked and repaired.
You will need: key "for 10" (a socket head is more convenient), phillips-head screwdriver, long-nose pliers.
1. Drain the coolant (see "Replacing the coolant").
2. Remove the radiator electric fan (see "Removing and installing the radiator electric fan with casing").
3. Remove the sound signal (see "Removal, installation and adjustment of the horn").
4. Loosen the clamp securing the supply hose to the radiator...
5. ...and remove the hose from the radiator pipe.
6. Similarly, disconnect the drain hose from the radiator.
7. Unscrew the two nuts securing the radiator to the body.
8. Remove the steam hose holder from the opening in the upper cross member of the engine compartment.
9. Tilt the radiator towards the engine. Loosen the steam hose band clamp…
10. ...and remove the hose from the radiator nipple.
Note. Tape clamps for attaching hoses are inconvenient to use, they are difficult to re-ensure the tightness of the connection. We recommend replacing the band clamps with commercially available worm-drive clamps when disconnecting the hoses for the first time.
11. Remove the radiator upwards.
12. Remove the two lower mounting pads from the radiator if they remain on the radiator mounting pins or remove them from the holes in the crossmember if they remain on the body. Replace torn or loose cushions.
13. Remove the rubber-metal bushings from the radiator brackets. Replace torn or loose rubber bushings.
14. Rinse the radiator from the outside with a stream of water and dry it. If there are cracks in the plastic radiator tanks, replace the radiator.
15. Check the radiator for leaks by plugging its pipes and lowering it into a container with water, supplying it with air under a pressure of 0.1 MPa (1 kgf/cm²). No air bubbles should appear from the radiator for at least 30 s. If the radiator does not fit completely into the container, check it sequentially from all sides.
16. Install the radiator in the reverse order of removal, after first placing the lower mounting cushions on the radiator pins and inserting the upper mounting bushings into the brackets.
Note: To prevent future coolant leaks, apply a thin layer of sealant to the radiator hoses before connecting them to the radiator.
17. Install the electric fan and all removed parts in the reverse order of removal.
18. Fill with coolant (see "Replacing the coolant").
