As a result of long-term operation of the car, the radiator channels can become clogged with limescale deposits. As a result, the efficiency of the radiator is sharply reduced, and the engine overheats. In this case, it is necessary to replace the radiator.
Removal
Disconnect the ground (-) cable from the battery.
Warning: This will erase the on-board computer records, in particular the fault records and the radio receiver code. Before disconnecting the battery, please read the section "Removal and installation the battery".
Drain the coolant.
Disconnect the upper and lower coolant hoses at the radiator, first opening and sliding the clamps back.
Disconnect the expansion tank hose from the radiator, having first opened the clamp.
Remove the expansion tank.
Disconnect the cable from the temperature sensor near the radiator.
Remove the upper radiator mounting bolt.
Tilt the radiator back and remove it together with the fan.
If this cannot be done, then the fan is removed first.
Caution: Radiator fins may have sharp edges. It is therefore recommended to use gloves when doing this.
Note: If the radiator is to be dismantled for more than 48 hours, it must be washed with clean water, blown with compressed air and closed with plugs. The radiator can be stored filled with coolant and with the holes closed. Otherwise, corrosion may occur and, as a result, the system may become leaky.
Installation
If necessary, move the temperature sensor and fan to the new radiator.
Check all coolant hoses for cracks, cuts, or other damage.

Replace the hoses if necessary. Check the condition of the rubber radiator mounting pads.
Install the radiator in place so that the radiator support pins fit into the rubber pads of the lower bracket.
Tilt the radiator forward, install the upper radiator mount and secure it.
Install the upper and lower coolant hoses and secure them with clamps.
Put on the expansion tank hose and secure it with a clamp.
Secure the electrical wires to the temperature sensor and fan.
Install the expansion tank.
Fill the system with coolant, see section "Maintenance".
Connect the ground (-) cable to the battery.
Set the time on the clock, if there is one, and enter the security code into the radio.
Start the engine and check the hose connections and radiator for leaks.
Check the coolant level. Top up with coolant if necessary.
