Withdrawal
Drain the coolant.
Remove the front bumper.
Disconnect the upper and lower hoses from the radiator. To do this, remove the fixing brackets (see fig. 3.3) on the side of the couplings, then disconnect the hoses.
Cars with automatic transmission. Clear places of connections of pipelines and disconnect pipelines from an oil cooler of cooling of a transmission. Wipe up spilled oil with a rag. At the same time, make sure that dirt does not get into the pipelines. Protect open pipelines from contamination with plastic plugs and rubber rings.
Unscrew Power Steering Hydraulic Oil Cooler (at the bottom of the radiator, fig. 3.25). Do not disconnect the pipelines, otherwise oil will leak out.
Cars with air conditioning
Safety instructions. Do not open the air conditioning circuit. Refrigerant may cause frostbite if it comes into contact with skin. The pipes and hoses of the air conditioning system must not be twisted, bent or bent.
Unscrew screws 4 on both sides of the radiator and remove the air guides (pic. 3.26).
Unscrew bolts 1 and 2 securing the condenser to the radiator and move it forward as far as possible (pic. 3.26).
Disconnect the electrical connector 3 of the air conditioner (pic. 3.26).
Suspend the condenser with a soft wire so that the hoses/pipes are relaxed.
Remove the top radiator mounts (see fig. 3.27).
Tilt the heatsink forward and remove it from the rubber mounts along with the fan shroud and fan.
Examination
If the radiator was removed due to a decrease in throughput, flush it with a jet of water in two directions. Blow out the radiator with compressed air.
If the radiator is leaking, do not attempt to weld or solder the leak. the plastic parts of the radiator will be damaged.
Minor radiator leaks can be repaired using radiator sealant.
Installation
Replace worn rubber radiator mounts.
Install the heatsink with fan from above.
Secure the top of the radiator with the clips.
Use new O-rings for the coolant hoses. Connect the coolant hoses to the radiator and secure with retaining clips.
Screw the power steering hydraulic oil cooler to the bottom of the radiator and tighten its fastening bolts to 10 Nm.
Cars with air conditioning. Screw the condenser and air guides to the radiator by tightening their fastening bolts to 10 Nm. Connect the electrical connector of the air conditioner (see fig. 3.26).
Cars with automatic transmission. Screw the transmission cooling lines with new O-rings to the radiator. Soak the O-rings in oil before installation. Top up the oil in the automatic transmission at a service station.
Connect the electrical connectors to the temperature sensor and radiator fan and secure their wires in the holders.
Install the front bumper.
Pour coolant into the cooling system and bleed air from the system.
Attention. When installing a new radiator, the coolant must be completely renewed.
After a test drive, check the tightness of all connections.
