We remove the radiator for replacement or for access to other units
Tools will be required: keys for 7; Torx T30; socket head for 10; pliers; screwdriver with a flat blade; container for the drained liquid.
We install the car on a viewing ditch or a lift.
We remove the front bumper (article - Removing and installing Renault Duster bumpers)
Removing the radiator fan (article - Removing the Renault Duster engine cooling radiator fan)
To access the radiator mounts, the plastic radiator and air conditioning condenser deflector must be removed.
The deflector is attached to each side of the car with three clips.
Using the TorxT30 wrench, unscrew the retainer of the right-hand deflector fastening clip to the upper cross member of the radiator frame.
Using the TorxT30 key, we unscrew the clamps of the two clips of the right fastening to the front bumper beam.
We also unscrew the latches of the three caps of the left deflector mount.
Removing the clips
And remove the radiator and condenser deflector.
We substitute a container for draining the coolant under the lower radiator pipe
With sliding pliers, we compress the ends of the clamp for fastening the radiator outlet hose and slide the clamp along the hose.
At the factory, the hoses are installed on the radiator pipes with sealant.
Therefore, if it is difficult to remove the hose from the radiator pipe, insert a flat screwdriver into the gap between the pipe and the hose.
Moving the screwdriver around the circumference of the pipe, pry off the hose and remove it from the lower radiator pipe, draining the coolant into the substituted container.
With sliding pliers, we compress the ends of the clamp for fastening the radiator inlet hose and slide the clamp along the hose.
Remove the radiator inlet hose from the upper radiator pipe.
If it was not possible to disconnect the hose from the nozzle (because the nozzle is in a hard-to-reach place), then you can disconnect the upper end of the hose from the nozzle of the thermostat cover.
With a head of 8, we unscrew the four screws securing the condenser system Air conditioning fittings to the radiator.
Without disconnecting the refrigerant inlet and outlet pipes from the condenser, lift it, removing its bracket from the holder on the radiator (arrow in the figure).
We also remove the bracket for the upper left mount of the capacitor from the holder on the radiator.
We tie the capacitor to the upper cross member of the radiator frame
Remove the radiator from the engine compartment
We check the tightness of the radiator in a bath of water.
Having plugged the radiator pipes with plugs, we supply compressed air to it through one of the plugs at a pressure of about 1 bar (1kgf / cm 2) and lower the radiator into a bath of water.
In this case, no air bubbles should be observed.
Install the radiator in reverse order.
Fill in the coolant (article - Checking and replacing the coolant of the Renault Duster engine).
