In a workshop with special equipment, the radiator can be checked and repaired.
WARNING: Remove the radiator only when the engine is cold.
NOTE: For clarity, the work is shown on a car with the front bumper removed.
1. Disconnect the wire from the negative terminal of the battery.
2. Drain the coolant (see Replacing the coolant).
3. Remove the mudguard and engine crankcase protection (see Removing and installing mudguard and engine crankcase protection).
4. Squeeze the clips of the electric fan control unit wiring harness connector and disconnect the connector from the terminals of the unit.
5. Disconnect the coolant outlet hose from the radiator.
6. Similarly, disconnect the upper supply hose from the radiator pipe.
7. Unscrew the upper radiator fasteners…
8….and take them off.
9. Unscrew the two front crossmember mounting bolts and remove the crossmember together with the radiator and electric fan. If necessary, remove the radiator from the crossmember.
NOTE: This is the location of the crossmember mounting bolts.
10. Rinse the radiator from the outside with a stream of water and dry it. If cracks appear on the plastic radiator tanks, replace the radiator.
11. Check the radiator for leaks by plugging its pipes, supplying air to the radiator 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.
12. Install the radiator and all removed parts in the reverse order of removal.
USEFUL TIP: To prevent future coolant leaks, lubricate the radiator pipes with a thin layer of silicone sealant before installing the hoses.
13. Fill the coolant and remove air locks from the cooling system (see Replacing the coolant).
