1. Drain the cooling system (see "Replacing the coolant").
2, Remove the radiator electric fan (see "Removal and installation of the electric fan of the radiator of the engine cooling system").
3. Loosen the clamp securing the radiator outlet hose by squeezing its bent ears with pliers, slide the clamp along the hose and remove the hose from the radiator pipe.
4. Disconnect the radiator supply hose in the same way.
5. Remove the front bumper (see "Removal and installation bumpers").
6. Pry up the edges of the air intake holder...
7. ...and remove the holder, overcoming the resistance of the clamps.
8. Remove the bolt securing the air intake to the upper cross member of the radiator frame.
9. Remove the air intake.
10. Remove the bolt securing the right bracket of the upper radiator support to the upper cross member of the radiator frame.
11. Remove the top bracket.
12. Remove the bolt securing the right bracket...
13. ...and remove the upper support bracket.
14. Remove the four bolts securing the front bumper bracket to the upper cross member of the radiator frame.
15. Using a screwdriver, lift up the clips of the three pins securing the front bumper bracket to the upper cross member of the radiator frame...
16. ...and remove the pistons.
17. Remove the bracket.
18. Having pressed the clamps...
19. ... remove the condenser brackets on the left and right (air conditioner radiator) from the holders on the radiator tanks of the cooling system.
20. After lifting the radiator, remove the pins of the lower radiator supports from the rubber cushions and remove the radiator.
21. Remove the cushion from the upper support pin.
22. Remove the cushion from the lower support pin or remove it from the hole in the lower radiator frame bracket. Replace heavily compressed or hardened cushions.
23. Rinse the radiator from the outside with a stream of water and dry it. If cracks are found on the plastic radiator tanks, replace the radiator.
24. Check the radiator for leaks by plugging the radiator pipes, supplying air to it under a pressure of 0.1 MPa (1 kgf/cm²) and lowering it into a container with water for at least 30 s. Leaks in the radiator are determined by the air bubbles that come out. If the radiator does not fit into the container entirely, check it sequentially from all sides.
25. Install the radiator in the reverse order of removal.
To prevent future coolant leaks, lubricate the radiator pipes with a thin layer of silicone sealant before installing the hoses.
26. Fill the coolant and remove air locks from the cooling system.
