Can radiator fan be replaced without disassembling the unit?

Recommended Posts

Durametric says I have a problem with the passenger side radiator fan.  Using the Actions controls to turn on the radiator fans, the passenger side fan does not turn on in either low or high setting.  Previously while replacing brake pads I removed the wheel well liner and inspected the radiator unit.  The fan turns freely when manually pushed but does not turn under computer control.  So the fan motor appears to have failed.  Driver's side fan works fine.

 

The fan is mounted to the radiator as a unit and it appears impossible to remove just the fan without removing the whole unit, and given the tight space it appears necessary to disconnect the unit from the cooling hoses to do so.  I was hoping to avoid this and replace just the fan.  I have searched and there are numerous sources for replacing the whole unit but none (that I've found) that discuss whether the fan can somehow be removed and replaced by itself.  Does anybody know if this can be done?

Next time, try looking up the parts in the Porsche PET system.  Your passenger's side fan is available as a separate part, #99762412802, and retails for a tad under $450..

I would try to put 12v on the fan, to see if it runs.  There is a fan control module, which can fail.  Ask me how I know....

Thanks JFP; I was aware that the fan can be bought as a separate part but was asking if the replacement of the fan alone can be done without removing the whole unit from the car.  Sorry for confusion on the question.

You can access the fan and radiator by removing the front fascia and wheel well liner, and then moving a couple other items out of the way.  This is from a 996, but yours in not that different:

OK, thanks JFP.  I found the Pelican photos too but it is not obvious from the photos alone that the unit can be loosened enough to remove the fan without disconnecting the hoses and removing the whole assembly.

If you look at the exploded parts diagram above, you will see that the fan is mounted into a shroud, which is then held in by a couple of fasteners.  You do not need to drain and remove the radiators, or the AC heat exchangers, they remain in the car.

      Hi all,
      I have noticed that after my last service at the dealer the engine runs about 8 degrees warmer (about 220f) and the rear fan runs for extended periods after I shut the engine off. The oil pressure also seems to be lower than it was before the service, which included oil change, coolant flush, and coolant replacement. Any ideas on why this might be happening would be greatly appreciated. Thanks in advance.

      The radiator grills on the 986 sit very low and thus tend to collect quite a bit of debris and garbage faster than other cars.  The design of the radiators and front air intakes is such a way that any debris which enters the grill get jammed between the radiator and the inside of the front bumper body panel.  
      Cleaning out your radiators and the garbage stuck behind the front bumper should be done periodically as leaving anything in there can cause inefficiencies to your cooling (A/C and engine) and also rust your radiators once the debris gets wet.  
      By adding mesh to the standard grill, using gutter guards for rain gutters, you can reduce the amount of debris which can enter your grill.  This is a simple process and adds not only functional value, but I think it looks pretty great too.  For me it took roughly 4 hours to access, clean the radiators and air intakes, and add the mesh to my front grills(not including painting the grills).
      Parts you'll need:
      •    Gutter Guard (this is the same stuff you use for rain gutters on a house to keep leaves and junk from building up in the gutter) - Buy two sheets of this.
      •    High gloss, black spray paint
      •    Tiny black zip ties - nothing too thick, but don't go too wimpy either.  You'll need about 4 zip ties.
      Tools you'll need:
      •    Torx set
      •    Vacuum
      •    Aluminum shears
      •    Wet rag and soap to wipe down the air intake duct which is likely dirty.
      I won't cover how to remove the front bumper, as that's available widely across Youtube, Renntech, and other DIY sites.  Here's the Youtube video I used (https://www.youtube.com/watch?time_continue=280&v=X2q54XtupVo).  
      So we'll get started with this tutorial once you have the front bumper cover removed.

      1.    The first step is to remove the grills which are held in place with 4 plastic tabs and pull out from the inside of the front bumper cover.  This is fairly straight forward – just be sure to follow the general rule of not trying to force anything!  Use the images below to help.


       
      From this image, you can see 4 plastic tabs are used to secure the grill in place, while 3 tabs on top are flat and just used to align the grill.
      2.    With the grills out, it’s time to trace them on paper so you can cut your mesh correctly.  I used a big sheet of painters drop paper, which I’ll later use when painting the grills, to trace around the whole perimeter of the grill piece.  It’s important to trace around the whole piece rather than just the vent portion, because the grill is rounded and so the mesh will need to bend in order to make this a tight fit.  If your mesh is too small debris will be able to make it past your grill.
      3.     Now it’s time to cut your gutter guard.  Using the metal shears, cut the mesh to match the outline you traced in step 2.  I found it easy to use a box knife to score and transfer the tracing from the paper to the gutter guard (since the gutter is painted, you just use the box knife to score the paint).

      Your cuts don’t need to be perfect.  Mine aren’t rounded, but you’ll see that they still create a great seal for stopping junk.
      4.    This next step is optional, though it makes a big difference in terms of looks!  I painted by grills.  There’s nothing fancy you need to do when painting them.  I applied three coats of paint just to ensure it was solid.  Let them dry for at least a day or two or else the paint will easily chip.   
      5.    The next step is to cut a whole out for the outside temp sensor which is sticks through the left grill (when looking at the car head on).  Before cutting the hole for the sensor, be sure to test out your mesh by holding it against and fitting it (bending it to form) with the respective grill it’s for.  
       This doesn’t need to be an exact science, and in this case it’s always better to cut less and test it rather than cut too much.
      I determined where the hole needed to be cut by holding the fitted mesh against the grill and scoring the part of the mesh which aligned with the hole on the grill.  I cut a small rectangle that is about a half inch, or in my case three snips of the mesh.  I probably couldn’t gone a bit smaller, but you can’t really notice. 
       

      6.    Next step is to adhere the mesh to the grill.  I did this a bit differently than others have since I didn’t’ want the mesh to be permanently attached to the grill.  I used small black zip ties which aren’t visible when viewing the car but hold the mesh securely in place and allow it to be replaced if they become damaged or a future owner doesn’t want them.  In the picture below you can see I used 4 zip ties for each grill.  Two on the very bottom which help support the mesh from sliding down, and two at the very top which help the mesh from being pushed back into the intake duct. 

      7.    The most difficult part of reassembly is aligning the outside temp sensor with the hole you made.  Prior to having mesh installed this was simple because you could just put your fingers in the grill and guide it.  There’s no trick to this, just take your time aligning it as you put the bumper panel back on.  It doesn’t need to be aligned perfectly since you can use needle nose pliers to adjust it after the bumper panel is in place.

      List Mates, I have a 2002 996 c4. When my Air conditioner compressor is activated the volume of air coming out of the vents is decreased dramatically.  It still blows cold but just very very low volume or amount. I have had it recharged , checked leaks , replaced condensors etc but nothing changes. As soon as you switch the ac off ( snowflake button) the volume of air through the vents goes right back up.  Volume of air is fine on heat , defrost etc.  I have never had this issue with any other vehicle. Any ideas as to what the problem may be?

      Hello All,
      The car has been awesome 2006 987.1 30k miles. The other day i took it for a drive and stopped after about 150 miles for about 30miins when I came out, all my coolant was on the floor. I refilled the coolant and constantly checked the temperature, initially it edged up to 180F but then settled back down to 175F and stayed that way all the way home. I was driving gently and kept cheeking the coolant level. Since then I found that I needed to open the coolant needle valve and drive around for 3 or 4 days to bleed the cooling system. I'm on day 2 and the coolant level has gone down slightly. Whenever I stop I check the floor and there has been no coolant leak.
      I am baffled, anyone seen this before?
      Thanks.
