Removal
1. Disconnect the negative cable from the battery.
2. If present, disconnect the connector from the coolant level sensor located on the right side of the radiator.
3. If present, disconnect the connector from the radiator fan switch located on the left side of the radiator.
4. Drain the coolant from the cooling system.

5. Disconnect the mounting clamp (drawing on the left) air supply pipe and remove the air supply pipe located above the radiator (drawing on the right).
6. If available, disconnect the connector and vacuum hose from the MAP sensor located at the top of the radiator, then unscrew the two bolts securing the sensor mounting bracket and remove the sensor.
7. Disconnect the upper radiator hose from the left front end of the radiator.
8. Disconnect the lower radiator hose from the right side of the radiator. On some models, to access the lower radiator hoses (indicated by arrows) it is necessary to remove the radiator grille.
9. Remove the two brackets securing the top of the radiator and tilt the radiator back.
10. Carefully remove the radiator so as not to damage the radiator fins. Be careful not to lose the lower rubber support of the radiator.
Examination
1. If the radiator was removed due to a decrease in throughput, flush it with a stream of water in both directions. Blow the radiator out with compressed air from the outside.
2. If the radiator is leaking, do not try to weld or solder the leak, as this will damage the plastic parts of the radiator.
3. Minor radiator leaks can be repaired using radiator sealant.
4. Check the condition of the lower rubber radiator mounts and replace them if necessary.
Installation
Installation is carried out in the reverse order of removal, taking into account the following points:
- check that the lower tabs on the radiator are correctly installed in the front cross member;
- when connecting hoses to the radiator, use new O-rings in the connectors;
- finally, fill the cooling system.
