How to install fan assembly for pt cruiser

Hi;
The Ligths turns on? is the Battery ok? Honks the Horn?
How long is the car unused?
Can you test the battery charge?How many Volts of current (DC Volts)have?
Did you check the Fuses?sometimes the fuse is blown(There is a Fuse for starter and ignition)See fuses box and check.
If all is ok, check under the car the starter cables.
Other tip the battery clamps are rusted,dissasembly,wash with current water,use some sand paper to clean ans assembly again.

Turbo Radiator Fan

The radiator cooling fan is a variable speed electric motor driven fan. The radiator fan assembly includes an electric motor, fan blade, and a support shroud that is attached to the radiator. The radiator fan is serviced as an assembly (fan motor/fan/shroud).

The variable speed radiator fan is controlled by the Powertrain Control Module (PCM) by way of a Pulse Width Modulated (PWM) signal. The duty cycle ranges from 30% for low speed operation then ramps-up to 100% for high-speed operation. This fan control system provides infinitely variable fan speeds, allowing for improved fan noise, A/C performance, better engine cooling, and additional vehicle power.

To control radiator fan operation, the PCM looks at inputs from:

Engine coolant temperature
A/C pressure transducer
Ambient temperature
Vehicle speed
Transmission oil temperature (automatic transmission only

HENCE CHECK THE PCM

Needs to be same make of car, year, and engine size, to work.

Hope this helps!

Removal & Installation
NOTE The fan motor, fan, and the shroud are serviced as an assembly.



CAUTION Do not open the radiator draincock with the system hot and under pressure, because serious burns from coolant can occur.

1. Disconnect negative cable from battery.
   
2. Remove battery and battery tray.
   
3. Drain cooling system below upper radiator hose level.
   
4. Remove grille.
   
5. Remove upper radiator closure panel and center brace.
   
6. Disconnect upper radiator hose from radiator.
   
7. For turbocharger equipped vehicles: Remove radiator inlet neck.
   
8. Hoist vehicle.
   
9. Disconnect radiator fan electrical connector (.
   
10. Remove the two lower and left side radiator fan screws and.
    
11. Lower vehicle and remove the remaining radiator fan attaching screws.
    
    WARNING Care should be taken not to damage the radiator cooling fins and tubes during fan removal.
    
    
12. Remove radiator fan by lifting up from the engine compartment.
    

Radiator fan mounting points

To install:

1. Install the radiator fan into position on the radiator.
   
2. Hand-start all radiator fan fasteners.
   
3. Tighten all radiator fan retaining screws to 55 inch lbs. (6 Nm).
   
4. Connect the radiator fan electrical connector.
   
5. Carefully lower the vehicle.
   
6. For turbocharger equipped vehicles: Inspect radiator inlet neck O-ring. Replace if necessary. Install radiator inlet neck. Torque fasteners to 55 inch lbs. (6 Nm).
   
7. Connect the upper radiator hose to radiator. Align hose and position clamp so it will not interfere with the engine or the hood.
   
8. Install upper radiator closure panel and center brace.
   
9. Install grille.
   
10. Install battery tray and battery.
    
11. Connect cables to battery.
    
12. Fill cooling system.
    

Check the voltage output of your car with the engine running. It should read 13 to 14 volts. only. Higher than this will cause damage to the fan motor, and other 12v gadgets in your car. Is this happening? If not, then, check the aircon evaporator for grounded wiring connections. This is the line from the fuse box terminal to the line going to the aircon. Grounded line can cause a lower voltage reaching your fan motor, forcing it to run undervoltage, overheating it. Send us your e-mail so we can give you further
assistance.

all the fan assembly's were new.I finally got a good one that lasted:)You could try a junk yard new they are about $ 110

have you tryed the thormostat or flushing the radiator

If the fan is coming on, you don't need a new fan. Is the A/C compressor cycling off and on with the fan? If the compressor is running fine, and the fan is the only thing cycling, I would suspect a relay first.

fan relay bad...fan motor assembly bad or bad ac pressure switch
