Note: If leakage is the reason for removing the radiator of Fiat Punto, bear in mind that minor leaks cart often be cured using proprietary radiator sealing compound, with the radiator in situ.

Removal
1  Disconnect the battery negative terminal.
2  Drain the cooling system.
3  Remove the electric cooling fan assembly.
4  Undo the bolt securing the horn mounting bracket to the front body panel. Disconnect the wiring connectors and remove the horn.

Models with automatic transmission

5  Remove the front bumper.
6  Working through the bumper aperture, undo the bolts securing the automatic transmission fluid cooler pipes to the front of the radiator of Fiat Punto car (see illustrations).

... and left-hand sides of the radiator (shown with radiator removed)


7  Undo  the  bolt  securing  the  automatic transmission fluid heat exchanger to the left-hand side of the radiator (see illustration).
8 Lift the heat exchanger upward to disengage the lower mounting lug from the grommet on the crossmember. Move the heat exchanger and fluid cooler pipes forward just sufficiently to allow removal of the radiator.

Models with air conditioning

9  Remove the front bumper.
10  Working through the bumper aperture, undo the bolts securing the air conditioning condenser to the front of the radiator. Suitably tie or support the condenser to avoid straining the refrigerant pipes.

All models

11   Tip the top of the radiator of Fiat Punto car toward the engine and lift it upward to disengage the lower mounting lugs from the grommets on the crossmember. Carefully manoeuvre the radiator up and out of the engine compartment (see illustration). Recover the lower mounting grommets H they are loose.

Inspection

12   If the radiator has been removed due to suspected blockage, it may be flushed out. Clean dirt and debris from the radiator fins, using an air line (in which case, wear eye protection) or a soft brush. Be careful, as the fins are sharp, and can also be easily damaged.
13   If necessary, a radiator specialist can perform a flow test on the radiator, to establish whether an internal blockage exists.
14   A leaking radiator of Fiat Punto car must be referred to a specialist for permanent repair. Do not attempt to weld or solder a leaking radiator, as damage to the plastic components may result.
15   Inspect the radiator rubber mounting grommets, and renew them if necessary.

Refitting

16   Refitting is a reversal of removal, bearing in mind the following points:
a) Ensure that the radiator lower lugs engage correctly with the lower mounting grommets.
b) On completion, refill the cooling system.
